- 1How Scholars Study ReligionThe academic study of religion tries to understand belief systems descriptively, explaining what followers believe and do without judging whether those beliefs are true. Scholars often look at several dimensions at once: beliefs and teachings, sacred stories, rituals, ethics, community institutions, and personal experience. The religious studies scholar Ninian Smart proposed a well-known seven-dimension model along these lines, which helps students compare traditions that look very different on the surface. A key skill is distinguishing insider perspectives, how believers describe their own faith, from outsider perspectives, how observers analyze it. Another is recognizing diversity inside every tradition, since no religion is practiced identically everywhere. Religions also change over time as they meet new cultures, rulers and ideas. Studying religion this way matters because religious ideas have shaped laws, art, wars, reforms and the daily lives of most people who have ever lived, and understanding them builds respect in diverse societies.
- 2Hindu Origins: The Indus Valley and the Vedic AgeHinduism has no single founder or founding date; it grew over thousands of years from many sources in South Asia. Some scholars see possible early links in the Indus Valley Civilization (c. 2600–1900 BCE), whose cities such as Harappa and Mohenjo-daro left seals showing animals and figures, though its script remains undeciphered and any religious meaning is debated. Clearer evidence comes from the Vedic period (c. 1500–500 BCE), when Sanskrit-speaking communities in northern India composed hymns to deities such as Agni (fire) and Indra, and priests performed elaborate fire sacrifices. Most historians link the Vedic culture to the arrival of Indo-Aryan speakers, while some Indian scholars argue for a more local origin, and this remains an active debate. Over time Vedic ritual blended with local practices and new philosophical ideas. Many Hindus call their tradition Sanatana Dharma, the 'eternal order', emphasizing timeless truth rather than a historical beginning.
- 3The Vedas and Upanishads: Hindu Sacred TextsHindu scriptures fall into two broad categories. Shruti ('what is heard') includes the four Vedas, believed by many Hindus to be eternal truths received by ancient seers, while smriti ('what is remembered') includes epics, law codes and Puranas composed by human authors. Each Veda contains hymns, ritual instructions and, at the end, philosophical texts called the Upanishads. The Upanishads shifted attention from outward sacrifice to inner knowledge, asking what the self is and how it relates to ultimate reality. Their famous teaching that the inner self (atman) is ultimately one with Brahman shaped later Hindu philosophy, especially the Vedanta schools. Because shruti was in Sanskrit and taught mainly to upper-caste men for centuries, access to it was restricted, which later reform movements challenged. The texts show how a ritual tradition developed a powerful philosophical side without abandoning its older practices.
- 4Brahman, Atman, Karma and MokshaSeveral connected ideas form the core vocabulary of most Hindu traditions. Brahman is ultimate reality, the source and ground of everything, while atman is the eternal self within each living being. Most Hindus believe the atman is reborn many times in a cycle called samsara, and that karma, the principle that actions have consequences, shapes the circumstances of future lives. The ultimate goal is moksha, liberation from the cycle of rebirth. Schools disagree about what liberation means: Advaita Vedanta holds that atman and Brahman are identical, so liberation is realizing that oneness, while devotional schools such as Ramanuja's teach that the soul remains distinct and lives eternally in loving relation to God. These ideas offered explanations for suffering and inequality, encouraged ethical conduct, and gave life a long-term purpose. Buddhism, Jainism and Sikhism share and reinterpret many of these concepts, showing how ideas move between related traditions.
- 5Dharma and the Four Aims of LifeDharma is one of the richest words in Hinduism, meaning duty, righteousness, law and the cosmic order that keeps the universe stable. Classical texts describe four legitimate aims of human life (purusharthas): dharma, artha (prosperity and success), kama (pleasure, love and beauty) and moksha (liberation). The scheme did not reject wealth or enjoyment; instead it placed them within ethical limits set by dharma. Texts also described four ideal life stages (ashramas): student, householder, forest dweller and renunciant, though historically only a minority followed the full sequence. Duties varied by age, gender and social group, so dharma was understood as context-dependent rather than one rule for all. Critics, both ancient and modern, have argued that tying duty to birth reinforced inequality, while defenders stress dharma's universal virtues such as non-violence, truthfulness and compassion. The concept explains how Hindu ethics balance worldly life with spiritual goals.
- 6Varna, Jati and the Challenge to CasteThe caste system is one of the most debated features of South Asian society. Ancient texts describe four varnas: Brahmins (priests and scholars), Kshatriyas (rulers and warriors), Vaishyas (merchants and farmers) and Shudras (laborers and servants). In practice, social life was organized by thousands of jatis, birth-based groups often tied to occupation, marriage rules and local status. Groups placed outside the varna order, historically called 'untouchables' and now often self-identified as Dalits, faced severe discrimination. Historians debate how rigid caste was before colonial rule, since British censuses classified and hardened categories. Many Hindu saints and reformers, from medieval bhakti poets to Gandhi, criticized caste prejudice, while B. R. Ambedkar argued that justice required rejecting the system entirely. India's 1950 constitution abolished untouchability and created reserved places in education and government for disadvantaged groups. Caste remains a significant social issue, discussed by Hindus and others alike.
- 7The Bhagavad Gita and the Three PathsThe Bhagavad Gita, a 700-verse dialogue within the epic Mahabharata, is one of the most widely read Hindu texts. On a battlefield, the warrior prince Arjuna hesitates to fight his own relatives, and his charioteer Krishna, revealed as a form of the divine, counsels him. Krishna teaches that Arjuna must do his duty without attachment to results, an idea called karma yoga. The Gita also presents jnana yoga, the path of knowledge, and bhakti yoga, loving devotion to God, which it describes with special warmth. By offering several paths to liberation, the text made spiritual goals accessible to householders and not only to renunciants. Readers have interpreted the battlefield in very different ways: Gandhi read it as an allegory of inner moral struggle and drew lessons of non-violence from it, while others read it more literally as a defense of righteous action. Its flexibility helps explain its enormous influence.
- 8The Ramayana and MahabharataIndia's two great Sanskrit epics are both sacred stories and shared cultural treasures. The Ramayana, attributed to the poet Valmiki, tells of Prince Rama's exile, the abduction of his wife Sita by Ravana, king of Lanka, and her rescue with the help of the monkey devotee Hanuman. The Mahabharata, traditionally attributed to Vyasa and traditionally reckoned at about 100,000 couplets, recounts a war between two branches of a royal family, the Pandavas and Kauravas. Both epics explore dharma through characters facing hard choices, and both are imperfect models: readers have long debated, for example, Rama's treatment of Sita. The stories spread across South and Southeast Asia, retold in Tamil, Hindi, Thai, Javanese and many other languages, and in dance, puppetry and film. Their reach shows how religious narrative can shape art, ethics and identity far beyond formal worship.
- 9Vishnu, Shiva, Devi and the Bhakti MovementMost Hindus focus their devotion on a chosen form of the divine, and three major traditions dominate. Vaishnavas worship Vishnu, the preserver, especially in his avatars Rama and Krishna; Shaivas worship Shiva, the ascetic and cosmic dancer who destroys in order to renew; and Shaktas worship the Goddess (Devi) in forms such as Durga and Kali. Many Hindus see these as aspects of one reality rather than competing gods. From about the 6th century CE, Tamil poet-saints such as the Alvars and Nayanars sparked the bhakti movement, which stressed personal, emotional love for God over ritual or caste status. Bhakti spread north through figures such as Kabir, Mirabai and Tulsidas, who wrote in local languages ordinary people understood. The movement opened religious expression to women and lower castes, though it did not dismantle caste altogether. Its songs remain central to Hindu worship.
- 10Puja, Temples and Home ShrinesHindu worship, called puja, often takes place at home as much as in temples. A family shrine may hold images (murti) of chosen deities, which worshippers greet, bathe, dress and offer flowers, food, light and incense to. Many Hindus understand the murti as a place where the divine is present, not merely a symbol, while some reform movements such as the Arya Samaj rejected image worship altogether. A central moment is darshan, seeing and being seen by the deity. Temples are designed as cosmic diagrams, with a dark inner sanctum (garbhagriha) beneath a towering spire, and regional styles differ: northern nagara temples have curved shikharas, while southern dravida temples have stepped vimanas and great gateway towers called gopurams. Priests perform rituals on behalf of worshippers, but there is no required weekly congregation. This flexibility helps explain how Hindu practice adapts to homes, villages and diaspora communities worldwide.
- 11Hindu Festivals and PilgrimageFestivals and pilgrimages give Hindu life its rhythm and bring communities together. Diwali, the festival of lights in autumn, celebrates the victory of light over darkness and is linked to stories such as Rama's return to Ayodhya and the goddess Lakshmi. Holi, in spring, is famous for throwing colored powder and celebrates renewal and the playful love of Krishna. Navaratri honors the Goddess over nine nights, and Durga Puja is a major celebration in Bengal. Pilgrimage (tirtha yatra) to sacred rivers, mountains and cities is believed to purify and bring merit. Varanasi, on the Ganges, is regarded as especially holy, and many Hindus hope to have their ashes immersed there. The Kumbh Mela, held in rotation at four river sites, draws vast crowds to bathe at auspicious times. Because the Hindu calendar is lunisolar, festival dates shift on the Gregorian calendar each year.
- 12Modern Hinduism: Reform, Gandhi and a Global FaithFrom the 19th century, Hinduism was reshaped by encounters with colonial rule, Christian missions and modern ideas. Ram Mohan Roy founded the Brahmo Samaj in 1828 and campaigned against sati, the burning of widows, which the British banned in 1829. Swami Vivekananda electrified the 1893 World's Parliament of Religions in Chicago by presenting Vedanta as a universal, tolerant philosophy. Mohandas Gandhi drew on Hindu ideas such as ahimsa and satyagraha ('truth-force') to lead mass non-violent resistance. At the same time, Hindu identity became politically charged, and debates continue in India over the relationship between religion and the state, with some emphasizing secular pluralism and others a Hindu cultural nationalism. Migration has carried Hinduism across the globe, to the Caribbean, East Africa, Britain, North America and beyond. Hinduism is the world's third-largest religion, with more than a billion followers concentrated in India and Nepal.
- 13Mahavira and the Jain Path of Non-ViolenceJainism emerged in the same northern Indian world of the 6th and 5th centuries BCE that produced Buddhism, a time when wandering ascetics questioned the authority of Vedic priests and sacrifice. Jains believe their teachings were revealed by a series of 24 Tirthankaras, 'ford-makers' who crossed the river of rebirth; the last was Vardhamana, known as Mahavira ('great hero'), an older contemporary of the Buddha. Jains hold that every living thing, even plants and tiny organisms, has a soul (jiva) weighed down by karmic matter, and that liberation comes through strict ethics and self-discipline. The central principle is ahimsa, non-violence, which leads many Jains to strict vegetarianism and to avoid occupations that harm life. Jains also stress anekantavada, the idea that truth has many sides and no single viewpoint grasps it fully. A small community of a few million, Jains have had outsized influence on Indian ethics, commerce and, through Gandhi, on non-violent politics.
- 14Siddhartha Gautama: The Life of the BuddhaBuddhism began with Siddhartha Gautama, a prince of the Shakya clan born at Lumbini in what is now Nepal; scholars place his life roughly in the 5th century BCE, though dates vary. According to tradition, he was sheltered in luxury until he encountered an old man, a sick man, a corpse and a wandering ascetic, the 'four sights' that revealed suffering and a possible path beyond it. He left home, practiced extreme fasting, and then rejected it for a 'Middle Way' between indulgence and self-denial. Meditating under a tree at Bodh Gaya, he attained enlightenment and became the Buddha, 'the awakened one'. He gave his first teaching at Sarnath and taught for about 45 years before dying at Kushinagar. Buddhists do not regard him as a god but as a human teacher who discovered and showed the path to liberation. His story models the journey from comfort to insight that Buddhists seek to follow.
- 15The Four Noble Truths and the Eightfold PathThe Buddha's first sermon at Sarnath set out the Four Noble Truths, often compared to a doctor's diagnosis. First, life involves dukkha: suffering, dissatisfaction or unease. Second, suffering arises from tanha, craving or attachment. Third, suffering can end; this cessation is nirvana, the 'blowing out' of craving. Fourth, the way to end it is the Noble Eightfold Path: right view, intention, speech, action, livelihood, effort, mindfulness and concentration, usually grouped into wisdom, ethics and meditation. Buddhism also teaches anatta (no permanent self) and anicca (impermanence), which distinguish it from the Hindu idea of an eternal atman. Karma and rebirth remain, but liberation means ending the cycle by uprooting craving and ignorance. Critics sometimes called the teaching pessimistic, while Buddhists answer that it is realistic and ultimately hopeful, since it insists suffering can be overcome by human effort.
- 16The Sangha and the Buddhist ScripturesBuddhists speak of the Three Jewels, taking refuge in the Buddha, the Dharma (his teaching) and the Sangha (the community). The Buddha founded orders of monks and, according to tradition after initial hesitation, of nuns, who lived by detailed monastic rules called the Vinaya. Monastics depended on lay people for food and support, while laypeople earned merit through generosity, creating an exchange that still shapes Buddhist societies. After the Buddha's death, teachings were preserved orally and organized at councils. The Pali Canon, or Tripitaka ('three baskets'), was written down in Sri Lanka around the 1st century BCE and contains the Vinaya, the discourses (Suttas) and philosophical analysis (Abhidhamma). Mahayana traditions added many later sutras, such as the Lotus and Heart Sutras, in Sanskrit, Chinese and Tibetan. The variety of canons shows that Buddhism, like other religions, debated which texts carried authority.
- 17Ashoka and the Spread of BuddhismBuddhism might have remained a regional Indian movement without the patronage of Ashoka, the Mauryan emperor who ruled most of the subcontinent in the 3rd century BCE. According to his own rock inscriptions, Ashoka was horrified by the bloodshed of his conquest of Kalinga (c. 261 BCE) and turned to dhamma, a policy of moral rule stressing non-violence, tolerance of all sects, and care for people and animals. He built stupas, sent envoys abroad and, according to Sri Lankan tradition, sent his son Mahinda to bring Buddhism to Sri Lanka. Historians caution that the edicts are royal propaganda and that Ashoka did not abolish his army or the death penalty, yet they remain remarkable early statements of humane government. Later, merchants and monks carried Buddhism along the Silk Roads to Central Asia and China, and by sea to Southeast Asia. Royal patronage and trade networks together turned a local teaching into a world religion.
- 18Theravada Buddhism in South and Southeast AsiaTheravada, 'the teaching of the elders', is the form of Buddhism found mainly in Sri Lanka, Myanmar, Thailand, Laos and Cambodia. It relies on the Pali Canon and emphasizes the historical Buddha's teaching, monastic discipline and the ideal of the arhat, a person who attains nirvana through their own practice. Monks in saffron robes make morning alms rounds, and laypeople gain merit by giving food, keeping the Five Precepts and attending festivals such as Vesak, which marks the Buddha's birth, enlightenment and death. Theravada Buddhism became closely tied to kingship and national identity: kings sponsored monasteries, and the Sangha lent rulers legitimacy. In modern times, monks have played varied public roles, leading pro-democracy protests in Myanmar in 2007, but also, in some cases, promoting religious nationalism. This range shows how a religion focused on inner peace can still be deeply bound up with politics.
- 19Mahayana Buddhism: Bodhisattvas, Pure Land and ZenMahayana, 'the great vehicle', developed in India around the start of the common era and became the main form of Buddhism in China, Korea, Japan and Vietnam. Its central ideal is the bodhisattva, a being who seeks enlightenment in order to help all living beings, motivated by compassion; figures such as Avalokiteshvara (Guanyin in China) became beloved objects of devotion. Mahayana thinkers such as Nagarjuna developed the idea of emptiness (shunyata), teaching that nothing exists independently. In East Asia, distinct schools grew. Pure Land Buddhism taught that sincere faith in Amitabha Buddha, expressed by reciting his name, leads to rebirth in a paradise where enlightenment is easier, an approach accessible to ordinary people. Chan, known in Japan as Zen, stressed meditation and sudden insight, often using puzzling sayings called koans. These schools show how Buddhism adapted to Chinese and Japanese culture while keeping core teachings.
- 20Tibetan Buddhism and the Dalai LamaVajrayana, 'the diamond vehicle', is a form of Mahayana Buddhism that flourished in Tibet, Mongolia, Bhutan and the Himalayas. It uses ritual, chanting of mantras, visualization and sacred diagrams called mandalas, and it stresses the role of a qualified teacher, or lama. Buddhism reached Tibet from India from the 7th and 8th centuries, and the Indian master Padmasambhava is revered for helping establish it. Tibetan Buddhism developed several schools; the Gelug school's leader, the Dalai Lama, became the political and spiritual head of Tibet from the 17th century. Tibetans believe Dalai Lamas are reincarnations, so a successor is found as a child through signs and tests. After China took control of Tibet in 1950 and an uprising failed in 1959, the 14th Dalai Lama fled to India, and Dharamsala became the center of the Tibetan exile community. The question of who will choose his successor is politically sensitive between Tibetan exiles and the Chinese government.
- 21Guru Nanak and the Origins of SikhismSikhism began in the Punjab region of northern South Asia with Guru Nanak (1469–1539), born in Talwandi, now Nankana Sahib in Pakistan. Punjab was a meeting place of Hindu and Muslim traditions, and Nanak's teaching responded to both. According to Sikh tradition, after a spiritual experience while bathing in a river, he declared, 'There is no Hindu, there is no Muslim,' meaning that God is beyond religious labels. He taught devotion to one formless God, remembered through meditation on the divine name (nam simran), and rejected caste distinctions, idol worship and empty ritual. Nanak traveled widely and later founded a community at Kartarpur, where followers worked, prayed and ate together. He set out a practical ethic summed up as nam japna (remembering God), kirat karni (honest work) and vand chhakna (sharing with others). Sikhism is not a blend of Hinduism and Islam, Sikhs stress, but a distinct revelation.
- 22The Ten Gurus and the Guru Granth SahibAfter Nanak, nine more human Gurus led the Sikh community from 1539 to 1708, each building its institutions. Guru Angad standardized the Gurmukhi script, Guru Amar Das strengthened the langar (communal kitchen), and Guru Ram Das founded the city of Amritsar. Guru Arjan compiled the Adi Granth, the first Sikh scripture, in 1604 and built the Harmandir Sahib; he was executed under the Mughal emperor Jahangir in 1606, becoming the first Sikh martyr. Rising tension with Mughal authorities shaped later Sikh history, and Guru Tegh Bahadur was executed in Delhi in 1675. Before his death in 1708, the tenth Guru, Gobind Singh, declared that there would be no more human Gurus: authority would rest in the scripture, now called the Guru Granth Sahib, and in the community. Sikhs treat the scripture as a living Guru, which is why it is installed with great respect in every gurdwara.
- 23The Khalsa and the Five KsIn 1699, at the spring festival of Vaisakhi in Anandpur, Guru Gobind Singh founded the Khalsa, the community of initiated Sikhs. According to Sikh tradition, he asked for volunteers willing to give their heads, and the five men who stepped forward, from different castes and regions, became the Panj Pyare, 'the five beloved'. They were initiated with amrit, sweetened water stirred with a double-edged sword, and the Guru then asked them to initiate him in turn, symbolizing equality. Initiated men took the name Singh ('lion') and women Kaur ('princess'), names that also challenged caste-based surnames. Khalsa members keep the Five Ks: kesh (uncut hair, usually covered by a turban), kara (steel bracelet), kanga (wooden comb), kachera (cotton undergarment) and kirpan (a small sword symbolizing the duty to protect the weak). The Khalsa gave Sikhs a visible identity and a commitment to defend justice at a time of conflict.
- 24The Gurdwara, Langar and the Golden TempleThe gurdwara, meaning 'door of the Guru', is the Sikh place of worship and community life. It houses the Guru Granth Sahib, and worshippers cover their heads, remove their shoes and sit on the floor, a sign of equality. Services include kirtan, the singing of scriptural hymns, and end with karah prashad, a sweet offering shared by all. Every gurdwara runs a langar, a free communal kitchen where anyone, regardless of religion, caste or status, may eat, usually seated together in rows on the floor. Langar turned the ideal of equality into daily practice in a society where caste rules often governed who could eat with whom. The most famous gurdwara is the Harmandir Sahib, the Golden Temple, in Amritsar, which has four entrances as a symbol of openness to all. Its history includes trauma: in 1984 the Indian army's Operation Blue Star against armed militants inside the complex caused many deaths and lasting grief.
- 25Heaven, Ancestors and Early Chinese ReligionLong before Confucius or Laozi, Chinese religious life centered on ancestors, spirits and Heaven. Under the Shang dynasty (c. 1600–1046 BCE), kings consulted ancestors and the high god Di by heating cattle shoulder blades and turtle shells and reading the cracks; questions and answers were carved on these 'oracle bones', the earliest substantial Chinese writing. The Zhou dynasty, which overthrew the Shang in 1046 BCE, justified its rule through the Mandate of Heaven (Tian), the idea that Heaven grants power to virtuous rulers and withdraws it from corrupt ones. Families honored their ancestors with offerings, believing the living and dead remained bound by mutual obligation. These ideas did not form a separate organized religion but ran through family, politics and daily life. They became the shared foundation on which Confucianism, Daoism and Chinese Buddhism later built, which is why Chinese religion is often described as a blended, rather than exclusive, tradition.
- 26Confucius and the AnalectsKong Fuzi, known in the West as Confucius (551–479 BCE), lived in the state of Lu during a time of disorder, as the Zhou kings' authority collapsed and rival states fought. He saw himself not as an innovator but as a transmitter of the wisdom of earlier sage-kings. He held only modest official posts, traveled seeking a ruler who would adopt his ideas, and spent much of his life teaching students from varied backgrounds. His conversations and sayings were collected by disciples after his death in the Analects (Lunyu). Confucius argued that social order depends on moral cultivation: if rulers and individuals practiced virtue and proper conduct, society would become harmonious without heavy reliance on punishments. Scholars debate whether Confucianism is a religion, a philosophy or an ethical tradition, since it says little about gods or the afterlife yet includes rituals, reverence for Heaven and temples to Confucius himself.
- 27Ren, Li and Filial Piety: Confucian VirtuesConfucian ethics revolves around a few key ideas. Ren, often translated as humaneness or benevolence, is the inner quality of caring for others; Confucius summed up one aspect of it as 'Do not impose on others what you do not wish for yourself'. Li means ritual propriety, the proper conduct, manners and ceremonies that express respect and hold relationships together. Xiao, filial piety, is respect and care for parents and ancestors, seen as the root of all virtue. Later Confucians described five relationships: ruler and subject, father and son, husband and wife, elder and younger brother, and friend and friend. Each carried mutual obligations, though four were hierarchical. Supporters see this as a recipe for stability, responsibility and respect for elders; critics, including Chinese reformers in the early 20th century, argued it reinforced authoritarian rule and the subordination of women and the young. The junzi, or exemplary person, embodies these virtues through lifelong learning.
- 28Mencius, Xunzi and the Debate over Human NatureConfucius's followers disagreed sharply about whether people are naturally good. Mencius (c. 372–289 BCE) argued that human nature is good: everyone has 'sprouts' of virtue, such as the instinct to rescue a child about to fall into a well, which education should nourish. He also taught that a ruler who oppressed the people lost the Mandate of Heaven, and that the people could rightly overthrow a tyrant. Xunzi (c. 310–235 BCE) argued the opposite: human nature is selfish, and goodness is the result of deliberate effort, ritual and teaching, much as a craftsman straightens warped wood. Both agreed that learning and ritual were essential, but for different reasons. Their debate parallels later Western arguments about human nature and has political consequences: a harsher view influenced Xunzi's students who became Legalists, advocates of strict laws. Mencius's optimism eventually won out as Confucian orthodoxy.
- 29Confucianism, the State and the Civil Service ExamsConfucianism became state orthodoxy under the Han dynasty, when Emperor Wu (r. 141–87 BCE) favored Confucian scholars and founded an imperial academy in 124 BCE. Over centuries, government service came to depend on mastering Confucian classics. The imperial examination system, expanded under the Sui and Tang and fully developed in the Song, selected officials through demanding tests, creating a scholar-official class. In theory, any man could rise through merit; in practice, wealthy families had more time and money for study, and women were excluded. Under the Song, Zhu Xi (1130–1200) created Neo-Confucianism, combining Confucian ethics with metaphysical ideas partly in response to Buddhism, and his commentaries became the official exam curriculum from 1313. Confucian ideas also spread to Korea, Vietnam and Japan, shaping governments and family law. The examinations were abolished in 1905, but the link between education, merit and public service remains influential.
- 30Laozi and the DaodejingDaoism takes its name from the Dao, 'the Way', the source and pattern of the universe, which cannot be fully captured in words. Its foundational text, the Daodejing, is traditionally attributed to Laozi, said to be an older contemporary of Confucius; many historians doubt he was a single historical person and date the text to around the 4th century BCE. Its 81 short chapters teach wu wei, often translated as 'effortless action' or 'non-forcing', acting in harmony with nature rather than struggling against it. The text praises softness and humility, using images such as water, which yields yet wears away rock. For rulers, it recommends governing lightly, warning that more laws can produce more disorder. Daoism offered a counterpoint to Confucian emphasis on ritual and social duty, and many Chinese drew on both: Confucian ideals for public life, Daoist ideals for private reflection and harmony with nature.
- 31Zhuangzi and Daoist PhilosophyAfter the Daodejing, the most important Daoist text is the Zhuangzi, named after a thinker who lived around the 4th century BCE. Unlike Laozi's brief verses, the Zhuangzi uses humorous stories, paradoxes and imaginary conversations to unsettle fixed ideas. In its most famous passage, Zhuangzi dreams he is a butterfly and, on waking, wonders whether he is a man who dreamed of being a butterfly or a butterfly dreaming he is a man. The book questions whether human labels such as useful and useless, right and wrong, are absolute; a gnarled tree survives precisely because it is useless for timber. It describes skilled people, such as a cook whose knife never dulls because he follows the natural joints of an ox, as models of effortless harmony with the Dao. Zhuangzi's relativism and humor influenced Chinese art, poetry and, later, Chan Buddhism, offering freedom from rigid social expectations.
- 32Religious Daoism: Immortals, Temples and RitualsDaoism is not only philosophy. From the 2nd century CE, organized religious Daoism developed with priests, scriptures, deities and communities. In 142 CE, according to tradition, Zhang Daoling received revelations from the deified Laozi and founded the Way of the Celestial Masters, which offered healing and moral rules to followers. Religious Daoists sought harmony with the Dao and long life, even immortality, through meditation, breathing exercises, diet, and, for some, alchemy. A pantheon of deities developed, including the Three Pure Ones and the popular Eight Immortals. Daoist priests performed rituals to purify communities and honor the dead, and temples became centers of local life. Daoism and Buddhism competed and borrowed from each other, and the Daoist canon (Daozang) grew to well over a thousand texts. Daoist influence reaches into Chinese medicine and practices such as tai chi and qigong, though their exact origins mix many traditions.
- 33The Three Teachings and Chinese BuddhismBuddhism arrived in China along the Silk Roads in the 1st century CE and gradually became one of China's major traditions. It faced resistance at first: critics called it foreign, and its monastic celibacy seemed to violate filial duties to produce heirs. Translators such as Kumarajiva (344–413) rendered Indian texts into fluent Chinese, sometimes using Daoist vocabulary, and pilgrims such as Xuanzang traveled to India for scriptures. Under the Tang, Buddhism flourished, though in 845 Emperor Wuzong ordered the closure of thousands of monasteries, partly to seize their wealth. Over time Chinese people spoke of the 'Three Teachings', Confucianism, Daoism and Buddhism, as complementary: a saying described them as three streams flowing into one river. Popular religion mixed them freely, so a family might honor ancestors in Confucian style, consult a Daoist priest and hire Buddhist monks for funerals. This blending contrasts with traditions that require exclusive membership.
- 34Shinto: The Way of the KamiShinto, 'the way of the kami', is the indigenous religious tradition of Japan. Kami are sacred powers or spirits found in nature, such as mountains, waterfalls, trees and rocks, as well as in ancestors and remarkable people. Shinto has no founder and no single scripture; its earliest written mythology appears in the Kojiki (712) and Nihon Shoki (720), compiled at the imperial court. These texts tell how the kami Izanagi and Izanami created the Japanese islands, and how the sun goddess Amaterasu became ancestor of the imperial line, an idea later used to support imperial authority. Shinto emphasizes purity, gratitude and harmony with nature, and treats impurity, not sin, as the main problem to be cleansed through ritual. Many Japanese people participate in Shinto rituals without considering themselves members of a religion, which makes counting followers difficult and shows that practice can matter more than doctrine.
- 35Shrines, Ise and MatsuriShinto worship centers on shrines (jinja), which number in the tens of thousands across Japan. A torii gate marks the boundary between the everyday world and sacred space, and visitors purify their hands and mouth with water before approaching. At the shrine, people may bow, clap and pray, buy amulets (omamori) for protection, or write wishes on wooden plaques called ema. The most sacred shrine is Ise, dedicated to Amaterasu, whose main buildings are rebuilt every 20 years in a ritual called Shikinen Sengu, renewing both the structures and the craft skills needed to build them. Communities celebrate matsuri, festivals in which kami are carried through streets in portable shrines (mikoshi), with music, dance and food. Life events are also marked at shrines, such as a baby's first visit and the Shichi-Go-San celebration for children. Shrine life shows how Shinto binds religion to community, nature and seasonal rhythm.
- 36Shinto, Buddhism and the State in JapanWhen Buddhism reached Japan from Korea in the 6th century, it did not replace Shinto. Instead, the two blended for over a thousand years in a system called shinbutsu-shugo, in which kami were often understood as local manifestations of buddhas and bodhisattvas, and temples and shrines shared grounds. After the Meiji Restoration of 1868, the new government ordered the separation of Shinto and Buddhism and promoted 'State Shinto', which presented reverence for the emperor and shrines as a patriotic civic duty rather than a religion. This system supported nationalism and militarism up to 1945. After Japan's defeat, the Allied occupation's Shinto Directive of December 1945 ended state support, Emperor Hirohito's 1946 rescript renounced the idea of his divinity, and the 1947 constitution separated religion and state. Visits by politicians to the Yasukuni Shrine, which honors Japan's war dead, including convicted war criminals, remain controversial with China and South Korea. This history shows how religious ideas can be used by states.
- 37Abraham and the CovenantJudaism traces its origins to Abraham, who, according to the Hebrew Bible, left Mesopotamia at God's call and settled in Canaan. Central to the story is the covenant (brit), a binding agreement in which God promises Abraham descendants and a land, and Abraham's family commits to worship God alone; circumcision became its sign. The narratives continue through Isaac, Jacob (renamed Israel) and Jacob's twelve sons, ancestors of the twelve tribes. Historians cannot confirm the patriarchs' lives with archaeological evidence, and they debate when the stories were written down, while many Jews read them as sacred history and others as foundational teaching narratives. Either way, the covenant idea shaped Jewish identity as a people bound to God by mutual obligation. Abraham is also honored in Christianity and Islam, which is why the three are sometimes called the Abrahamic religions. Understanding the covenant is key to understanding how Judaism links faith, law, peoplehood and land.
- 38Moses, the Exodus and the TorahThe central story of the Hebrew Bible is the Exodus: according to the narrative, the Israelites were enslaved in Egypt until God, through Moses, freed them, and at Mount Sinai gave them the Torah, including the Ten Commandments. The Torah ('teaching' or 'instruction') refers most narrowly to the first five books of the Bible, Genesis, Exodus, Leviticus, Numbers and Deuteronomy, and more broadly to all Jewish teaching. Tradition counts 613 commandments (mitzvot) in it, covering worship, ethics, diet, justice and care for the poor and strangers. Archaeologists have found no direct evidence of the Exodus as described, and scholars debate whether it reflects a smaller historical event, collective memory or later theological reflection. For Jews, its meaning is less about archaeology than identity: freedom from slavery, received law and the duty to remember. The phrase 'you were strangers in the land of Egypt' grounds repeated biblical commands to treat outsiders justly.
- 39Kingdom, Temple and ExileAccording to the Hebrew Bible, the Israelite tribes became a kingdom under Saul, David and Solomon, and Solomon built the First Temple in Jerusalem. After Solomon, the kingdom split into Israel in the north and Judah in the south. Assyria destroyed the northern kingdom in 722 BCE, and in 586 BCE the Babylonians under Nebuchadnezzar II captured Jerusalem, destroyed the Temple and deported many Judeans to Babylon. The exile was a crisis that could have ended the religion; instead, scholars believe it deepened it. Without Temple or king, exiles emphasized scripture, Sabbath, dietary laws and communal prayer, and prophets interpreted disaster as part of a covenant relationship rather than proof of God's defeat. When Cyrus the Great of Persia conquered Babylon in 539 BCE, he allowed exiles to return, and the Second Temple was completed around 516 BCE. This pattern of loss and renewal became a lasting theme in Jewish history.
- 40The Tanakh: Law, Prophets and WritingsThe Jewish Bible is called the Tanakh, an acronym of its three parts: Torah (Teaching), Nevi'im (Prophets) and Ketuvim (Writings). The Prophets include historical books such as Samuel and Kings and the words of prophets such as Isaiah, Jeremiah and Amos, who criticized injustice and called kings and people back to the covenant; Amos's line 'let justice roll down like waters' became famous worldwide. The Writings include Psalms, Proverbs, Job, Ruth, Esther and other works of poetry, wisdom and history. Christians later adopted these books as the Old Testament, though in a different order and, for Catholic and Orthodox Christians, with additional books. The Tanakh was written mostly in Hebrew, with parts in Aramaic, over many centuries; scholars date its canon's final closing to roughly the 2nd century BCE to the 2nd century CE. Its prophetic emphasis on social justice has influenced reform movements far beyond Judaism.
- 41From Temple to Rabbis: The Mishnah and TalmudIn 70 CE, Roman forces crushed a Judean revolt and destroyed the Second Temple, ending the system of priests and sacrifices. A second revolt led by Bar Kokhba (132–135 CE) ended in further devastation. Judaism survived by transforming: leadership shifted to rabbis, teachers learned in the Torah, and the synagogue and study house replaced the Temple as centers of religious life. Rabbis believed God had given Moses an Oral Torah alongside the written one, and they compiled its teachings in the Mishnah, edited by Rabbi Judah the Prince around 200 CE. Later generations' discussions of the Mishnah formed the Gemara; together they make the Talmud, of which the Babylonian Talmud (c. 500–600 CE) became most authoritative. The Talmud records debates, including minority opinions, showing a culture of argument and interpretation. This rabbinic Judaism is the basis of almost all Jewish practice today.
- 42Shabbat, Kashrut and a Life of MitzvotJewish practice weaves religion into everyday life through mitzvot, commandments. The Sabbath (Shabbat), from sunset Friday to nightfall Saturday, commemorates God resting after creation and the freedom from slavery; it begins with candles, blessings over wine and bread (challah), and family meals. Observant Jews refrain from work on Shabbat, which rabbinic law defines through 39 categories of creative labor, such as lighting fires or writing. Kashrut, the dietary laws, permits certain animals, forbids pork and shellfish, requires a particular method of slaughter, and separates meat and dairy. Supporters describe these practices as holiness in daily life and a 'palace in time', while others observe them partly or adapt them, reflecting differences among Jewish movements. Practices like the mezuzah on doorposts and prayer three times daily keep scripture present in ordinary spaces and hours, showing how Judaism emphasizes action as well as belief.
- 43The Synagogue and the Jewish Life CycleThe synagogue serves as a house of prayer, study and community. Its focus is the ark (aron kodesh), which holds the Torah scrolls and traditionally faces toward Jerusalem; an eternal light hangs before it. Communal prayer traditionally requires a minyan of ten adults, men in Orthodox practice and men and women in most other movements. Life-cycle rituals mark key moments. A boy's circumcision (brit milah) on the eighth day and naming ceremonies for girls welcome children into the covenant. At 13 for boys and 12 or 13 for girls, a bar or bat mitzvah marks religious adulthood, often by reading from the Torah in public; the bat mitzvah became widespread in the 20th century. Weddings take place under a canopy (chuppah) and end with breaking a glass, recalling the Temple's destruction even in joy. Mourners sit shiva for seven days and recite the Kaddish, a prayer praising God.
- 44The Jewish Year: Passover, the High Holy Days and HanukkahThe Jewish calendar is lunisolar, so festivals fall on different secular dates each year. Passover (Pesach), in spring, recalls the Exodus with a Seder meal at which families retell the story using the Haggadah, eat matzah (unleavened bread) and bitter herbs, and ask the Four Questions, traditionally voiced by the youngest child. Rosh Hashanah, the Jewish New Year in autumn, is marked by the blowing of the shofar (ram's horn), and ten days later comes Yom Kippur, the Day of Atonement, a 25-hour fast devoted to repentance and prayer. Sukkot follows, when families eat in temporary huts recalling the desert journey. Hanukkah, in winter, commemorates the rededication of the Temple after the Maccabean revolt against the Seleucid king Antiochus IV in the 2nd century BCE; its eight nights of candles recall a tradition about oil that burned for eight days. Hanukkah is a minor festival religiously, though it gained prominence in some countries alongside Christmas.
- 45Diaspora Worlds: Sephardic and Ashkenazi JewsAfter the Roman era, most Jews lived in the diaspora, scattered communities across the Middle East, North Africa and Europe. Two major cultural branches emerged. Sephardic Jews developed in Spain and Portugal, where under Muslim rule in the 10th–12th centuries Jewish poetry, philosophy and science flourished; the philosopher and legal scholar Maimonides (1138–1204), born in Córdoba, later served as a physician in Cairo. Ashkenazi Jews developed in the Rhineland and later Central and Eastern Europe, speaking Yiddish, a Germanic language with Hebrew elements. Mizrahi Jews lived continuously in Iraq, Iran, Yemen and elsewhere in the Middle East. Each community developed its own customs, music and prayer styles while sharing Torah, Talmud and core practice. Diaspora life depended on rulers' tolerance, which varied greatly: periods of prosperity alternated with restrictions and expulsions. This pattern explains both the remarkable diversity of Jewish culture and its vulnerability.
- 46Antisemitism and Persecution Through HistoryJewish history includes long periods of persecution, and studying it helps explain both Jewish experience and the nature of prejudice. In medieval Christian Europe, Jews were often blamed for Jesus's death, falsely accused of ritual murder in the 'blood libel', and blamed for the Black Death; massacres accompanied the First Crusade in 1096. Rulers frequently restricted Jews to certain professions such as moneylending and then expelled them, as in England in 1290 and Spain in 1492. Some communities in the Islamic world faced restrictions under dhimmi status, though experiences there varied widely over time and place. In the 19th century, religious prejudice was joined by racial antisemitism, which claimed Jews were a separate, dangerous race regardless of belief, and by violent pogroms in the Russian Empire. Historians stress that antisemitism repeatedly relied on conspiracy theories and scapegoating in times of crisis, a pattern that culminated in the Holocaust.
- 47Modern Jewish Movements: Reform, Orthodox and HasidicFrom the 18th century, Jews faced new choices as European states granted civil rights (emancipation) and Enlightenment ideas spread. The Haskalah, or Jewish Enlightenment, associated with Moses Mendelssohn (1729–1786), encouraged secular learning alongside Torah. In Germany, Reform Judaism emerged in the early 19th century, adapting worship to modern life with vernacular prayers and, later, mixed seating, and treating many ritual laws as non-binding. In response, Orthodox Judaism, articulated by figures such as Samson Raphael Hirsch, insisted on the binding authority of traditional law while engaging with modern society. Conservative (Masorti) Judaism sought a middle path. Separately, in Eastern Europe, Hasidism, founded by the Baal Shem Tov (d. 1760), emphasized joyful, mystical devotion and the leadership of charismatic rebbes. These movements reflect different answers to the same question: how to remain faithful to tradition in a changing world.
- 48The Holocaust, Israel and Jewish Life TodayThe 20th century transformed Jewish life. Between 1941 and 1945, Nazi Germany and its collaborators murdered about six million Jews, roughly two-thirds of Europe's Jews, in the Holocaust (Shoah), through mass shootings, ghettos and death camps such as Auschwitz-Birkenau. Whole communities and centuries-old cultures, especially Yiddish-speaking Eastern Europe, were destroyed. Survivors, scholars and religious thinkers struggled with how to remember and respond, and Holocaust memory became central to Jewish identity and to international human rights. In 1948 the State of Israel was established, a fulfillment of the Zionist movement's goals for many Jews, while the war that followed displaced hundreds of thousands of Palestinian Arabs, a history remembered very differently by Israelis and Palestinians. Jews today number roughly 15 to 16 million by recent demographic estimates, most living in Israel and the United States, and range from secular to ultra-Orthodox. Debates about identity, religion and the state continue within Jewish communities.
- 49Jesus of Nazareth in His Historical SettingChristianity centers on Jesus of Nazareth, a Jewish teacher from Galilee who lived in Roman-ruled Judea and was crucified in Jerusalem around 30–33 CE under the Roman governor Pontius Pilate. Most historians, whatever their beliefs, agree that he existed, was baptized by John the Baptist, taught about the coming 'kingdom of God', gathered disciples and was executed by Roman authorities. His teaching, recorded in the Gospels, used parables such as the Good Samaritan and the Prodigal Son and stressed love of God and neighbor, forgiveness and concern for the poor and outcasts. His context matters: Judea was tense under Roman occupation, and Jewish groups such as the Pharisees, Sadducees and Essenes disagreed about how to live faithfully. Christians believe Jesus rose from the dead and is the Messiah (Christ) and Son of God, beliefs that historians cannot test but that explain the movement's rapid growth among his followers. Jesus is also honored as a prophet in Islam.
- 50Core Christian Beliefs: Trinity, Incarnation and SalvationMost Christians share a set of core beliefs, though they express and interpret them in different ways. Christianity is monotheistic, but most churches teach that the one God exists as a Trinity: Father, Son and Holy Spirit. The incarnation is the belief that God became human in Jesus, who was fully divine and fully human. Christians believe Jesus's death and resurrection reconcile humanity with God, offering forgiveness of sin and eternal life, though churches have long debated how salvation is received: through faith, sacraments, good works, or a combination. Grace, God's freely given love, is central. Ethics flow from Jesus's command to love God and neighbor, including enemies. These doctrines were defined over centuries in creeds, especially the Nicene Creed, through debates that also divided churches. A small number of groups, such as Unitarians and Jehovah's Witnesses, reject the Trinity, showing that belief has never been entirely uniform.
- 51The New Testament: Gospels, Letters and RevelationThe Christian Bible adds the New Testament, 27 books written in Greek, to the Hebrew scriptures, which Christians call the Old Testament. The four Gospels, Matthew, Mark, Luke and John, tell the life, teaching, death and resurrection of Jesus; most scholars date them to about 65–100 CE and see Mark as the earliest. The Acts of the Apostles describes the early church's spread. The letters (epistles), many by the apostle Paul, were written to young congregations in the 50s CE and are the earliest Christian writings that survive. The book of Revelation uses vivid symbolic visions to encourage persecuted believers. The Gospels differ in emphasis and detail, which believers explain as complementary perspectives and historians analyze to understand how traditions developed. The list of accepted books was settled gradually; a list matching today's 27 appears in a letter by Bishop Athanasius of Alexandria in 367 CE.
- 52From Persecution to Empire: Paul, Constantine and NicaeaChristianity spread quickly through the Roman Empire, aided by Roman roads, the common Greek language and the missionary journeys of Paul, who argued that non-Jews could join without adopting Jewish law. This decision helped turn a Jewish movement into a separate religion with a largely Gentile membership. Romans often viewed Christians with suspicion for refusing to worship the emperor and traditional gods, and persecution occurred at intervals, most severely under Diocletian from 303. Everything changed with Constantine, who attributed his victory at the Milvian Bridge in 312 to the Christian God; the Edict of Milan (313) granted toleration, and in 325 he summoned the Council of Nicaea to settle disputes over Christ's divinity. In 380, under Theodosius I, Nicene Christianity became the empire's official religion. Historians debate whether this alliance with power strengthened the church or compromised it, and how sincere Constantine's conversion was.
- 53Monks, Nuns and the Monastic TraditionAs Christianity became powerful and comfortable, some believers sought a more demanding path by withdrawing from ordinary society. In the Egyptian desert, Anthony (c. 251–356) became a famous hermit, while Pachomius organized the first communities of monks living under a shared rule. In the West, Benedict of Nursia wrote his Rule around 530, balancing prayer, work and study under the motto often summarized as 'ora et labora' (pray and work). Benedictine monasteries preserved classical and Christian texts by copying manuscripts, ran schools and hospitals, and developed agriculture. Women's communities offered educated women opportunities rarely available elsewhere; the abbess Hildegard of Bingen (1098–1179) wrote on theology, medicine and music. Later orders, such as the Franciscans and Dominicans in the 13th century, lived among people in towns, preaching and serving the poor. Monasticism shows how religious ideals can shape education, economy and culture.
- 54East and West: The Great Schism and Eastern OrthodoxyOver centuries, Christianity in the Greek-speaking East and Latin-speaking West grew apart. Disagreements included the authority of the pope, whom Western Christians saw as head of the whole church while Eastern Christians saw him as first among equal patriarchs; the 'filioque' phrase added in the West to the Nicene Creed; and differences in practice such as leavened or unleavened bread. In 1054 papal legates and the Patriarch of Constantinople excommunicated each other, an event remembered as the Great Schism, though the split hardened gradually. The Fourth Crusade's sack of Constantinople in 1204 deepened Eastern bitterness. Eastern Orthodoxy developed a distinctive tradition centered on the liturgy, icons, the monasteries of Mount Athos and self-governing national churches in Greece, Russia, Serbia and elsewhere. In 1965 Pope Paul VI and Patriarch Athenagoras lifted the mutual excommunications, though the churches remain separate.
- 55The Medieval Church: Papacy, Sacraments and CathedralsIn medieval Western Europe, the Catholic Church shaped almost every part of life. The parish church marked baptism, marriage and death, and the seven sacraments, including the Eucharist (Mass) and confession, were understood as channels of God's grace. The church owned vast lands, ran schools and the first universities, and kept records. Popes claimed authority over kings: in 1077 Emperor Henry IV stood in the snow at Canossa to seek Pope Gregory VII's forgiveness during the Investiture Controversy over who could appoint bishops. The church also launched the Crusades from 1095 and established inquisitions against heresy, actions that historians assess critically. Gothic cathedrals such as Chartres and Notre-Dame de Paris, with soaring vaults and stained glass, expressed theology in stone and light and took generations to build. The medieval church was both a source of learning, charity and art and a powerful institution whose wealth and corruption provoked criticism.
- 56The Protestant ReformationIn 1517 Martin Luther, a German monk and professor, circulated his 95 Theses criticizing the sale of indulgences, certificates said to reduce punishment for sin. Luther came to argue that salvation comes by grace through faith alone, that scripture alone is the final authority, and that all believers share a priesthood. The printing press spread his ideas rapidly, and German princes protected him for religious and political reasons, including resentment of papal taxes. Other reformers followed: Ulrich Zwingli in Zurich, John Calvin in Geneva, who stressed God's sovereignty and predestination, and Anabaptists, who rejected infant baptism. In England, Henry VIII broke with Rome in 1534, initially over his marriage, founding the Church of England. The Reformation split Western Christianity permanently and led to religious wars, but also to translations of the Bible into everyday languages, wider literacy and, eventually, arguments for religious toleration.
- 57The Catholic Reformation and the JesuitsThe Catholic Church responded to the Protestant challenge with its own wave of reform and renewal, often called the Catholic Reformation or Counter-Reformation. The Council of Trent (1545–1563) reaffirmed Catholic doctrines that Protestants rejected, such as the seven sacraments and the role of tradition alongside scripture, while also tackling abuses: it banned the sale of indulgences and required seminaries to train priests. New religious orders emerged, most famously the Society of Jesus (Jesuits), founded by Ignatius of Loyola and approved in 1540, which emphasized education, disciplined spiritual exercises and missions. Jesuit schools spread across Europe, and missionaries such as Francis Xavier traveled to India and Japan. Baroque art and architecture expressed renewed Catholic confidence. The movement also used coercive tools, such as the Index of Forbidden Books and inquisitions, which historians weigh against its achievements in education and spirituality.
- 58Christian Missions and Global SpreadChristianity spread far beyond Europe, both before and during the age of European empires. The Church of the East reached China by 635, as recorded on the Xi'an Stele, and Christianity in Ethiopia dates to the 4th century, when King Ezana adopted it. From the 16th century, Spanish and Portuguese colonization brought Catholic missions to the Americas, Africa and Asia, while Protestant missions expanded greatly in the 19th century. The relationship between mission and empire was complex. Missionaries often accompanied conquest and suppressed Indigenous religions, and some forced conversions occurred; yet missionaries such as Bartolomé de las Casas condemned abuses of Indigenous people, and many mission schools and hospitals were valued. Local Christians, translators and evangelists did most of the work of spreading the faith, adapting it to their cultures. As a result, Christianity became a truly global religion, not merely a European export.
- 59Christian Worship, Sacraments and the Church YearChristian worship varies widely but shares common elements. Most churches practice baptism, a ritual of washing with water that marks entry into the faith, and the Eucharist (also called Holy Communion or the Lord's Supper), in which bread and wine recall Jesus's Last Supper. Churches differ on their meaning: Catholics and Orthodox believe the bread and wine become Christ's body and blood, while many Protestants see the act as a memorial or spiritual presence. Worship styles range from the incense, icons and chanted liturgy of Orthodox churches, to the Catholic Mass, to simple Quaker meetings held largely in silence. The church year structures time: Advent prepares for Christmas, Lent is 40 days of fasting and reflection before Easter, and Pentecost celebrates the coming of the Holy Spirit. Many Orthodox churches use the Julian calendar, so their Christmas usually falls on January 7. These variations show how one faith takes many forms.
- 60Global Christianity Today: Vatican II, Pentecostalism and the Global SouthChristianity is the world's largest religion, with roughly 2.3 to 2.4 billion followers, and its center of gravity has shifted dramatically. In 1900 most Christians lived in Europe and North America; today the majority live in Africa, Latin America and Asia. The Second Vatican Council (1962–1965) modernized the Catholic Church, allowing Mass in local languages, encouraging dialogue with other religions and affirming religious freedom. Pentecostalism, born in early 20th-century revivals such as the Azusa Street Revival in Los Angeles in 1906, emphasizes the Holy Spirit, healing and emotional worship, and it has grown enormously, especially in Africa and Latin America. Meanwhile, church attendance has declined in much of Europe. Christians today disagree on many social issues, and churches range from traditional to progressive. Studying these shifts reveals how a religion can change its geography, style and leadership while keeping core beliefs.
- 61Arabia Before Islam and the Life of MuhammadIslam emerged in 7th-century Arabia, a region of trading towns, oases and nomadic tribes. Mecca was a commercial center and home of the Kaaba, a shrine that then housed images of many deities and drew pilgrims; Jewish and Christian communities also lived in Arabia. Muhammad was born in Mecca around 570 into the Quraysh tribe, orphaned young and later worked as a trader, earning a reputation for honesty. According to Islamic tradition, in 610, while meditating in a cave on Mount Hira, he received the first revelation from God (Allah, the Arabic word for God) through the angel Gabriel (Jibril). Muslims regard him as the final prophet in a line including Abraham, Moses and Jesus. His message of one God, social justice and care for the poor challenged Mecca's powerful merchants, whose wealth was tied to pilgrimage to the Kaaba's many idols, and early Muslims faced hostility. His first wife, Khadija, was the first to accept his message.
- 62The Hijra and the Community at MedinaFacing growing persecution in Mecca, Muhammad and his followers migrated in 622 to the oasis town of Yathrib, later called Medina ('the city of the Prophet'). This migration, the Hijra, is so important that it marks year 1 of the Islamic calendar. In Medina, Muhammad became both religious and political leader, mediating among tribes; an agreement known as the Constitution of Medina set out rights and duties of Muslims, Jews and others in the community. Conflict with Mecca followed, including the battles of Badr (624) and Uhud (625), and tensions also arose with some Jewish tribes in Medina, episodes that historians reconstruct from Muslim sources written later. In 630, Muhammad entered Mecca with little fighting, removed the idols from the Kaaba and rededicated it to the worship of one God. He died in 632. The Medina period established the idea of the umma, a community bound by faith rather than tribe, and a model of religion and governance closely linked.
- 63The Quran: Revelation, Recitation and LanguageThe Quran ('recitation') is Islam's holy book, believed by Muslims to be the literal word of God revealed to Muhammad over about 23 years. It contains 114 chapters (surahs) arranged roughly by length, not chronology, and covers belief in one God, prophets, moral guidance, law, the afterlife and stories shared with Jewish and Christian scripture, such as those of Abraham, Moses and Mary. According to Islamic tradition, the text was memorized and written on various materials during Muhammad's life and compiled into a standard written copy under the third caliph, Uthman, around 650. Because Muslims believe its Arabic wording is divine, translations are regarded as interpretations, not the Quran itself. Recitation is an art form, and people who memorize the entire text are honored with the title hafiz. The Quran's style helped standardize classical Arabic, and its verses decorate mosques, making it central to Islamic art as well as faith.
- 64The Five Pillars of IslamThe Five Pillars are the core acts of worship that unite Muslims across cultures. The first, shahada, is the declaration of faith: 'There is no god but God, and Muhammad is the messenger of God.' The second, salat, is prayer five times a day facing Mecca, at times called by the adhan. The third, zakat, is obligatory almsgiving, usually 2.5 percent of savings above a minimum, given to the poor and needy. The fourth, sawm, is fasting from dawn to sunset during the month of Ramadan, building self-discipline and empathy for the hungry. The fifth, hajj, is pilgrimage to Mecca, required once in a lifetime for those physically and financially able. Together the pillars combine belief, personal devotion, social responsibility and global community. Exemptions, such as from fasting for the sick, travelers and pregnant women, show that the pillars are designed to be practicable rather than harmful.
- 65Hadith, Sharia and Islamic LawAlongside the Quran, Muslims look to the Sunnah, the example of Muhammad's words and actions, recorded in reports called hadith. Scholars developed careful methods to judge hadith reliability by examining chains of transmitters (isnad); collections such as those of al-Bukhari and Muslim are especially respected by Sunni Muslims. Sharia, often translated as Islamic law, literally means 'the path' and refers to God's guidance for life, while fiqh is the human effort to understand and apply it. Sharia covers far more than criminal law: most of it concerns worship, family life, business ethics, diet and charity. Sunni Islam developed four major schools of law, the Hanafi, Maliki, Shafi'i and Hanbali, and Shia Muslims follow the Ja'fari school; differences among them show that interpretation has always been plural. How sharia relates to modern state law is debated among Muslims, and countries vary from secular legal systems to ones that apply Islamic law in family matters or more broadly.
- 66Sunni and Shia: Origins and DifferencesThe division between Sunni and Shia Muslims began with a question of leadership after Muhammad's death in 632. The majority accepted Abu Bakr, a close companion, as caliph, and their descendants in faith became known as Sunnis, from 'people of the Sunnah'. A minority believed leadership belonged to Muhammad's family, specifically his cousin and son-in-law Ali, and became the Shia, from 'Shi'at Ali', the party of Ali. Ali became the fourth caliph but was assassinated in 661. In 680 his son Husayn and a small group of companions were killed by Umayyad forces at Karbala, an event Shia Muslims mourn each year on Ashura. Over time, differences developed in law, prayer details and religious authority; Twelver Shia, the largest branch, believe in twelve Imams, the last of whom is in hiding and will return. Sunnis make up roughly 85–90 percent of Muslims. Both share the Quran, the Five Pillars and core beliefs, and modern conflicts often owe as much to politics as to theology.
- 67Caliphates and the Expansion of the Islamic WorldWithin a century of Muhammad's death, Muslim rule stretched from Spain to Central Asia. The first four 'rightly guided' caliphs conquered much of the Byzantine and Sasanian Persian empires, which had exhausted each other in war. The Umayyad dynasty (661–750), based in Damascus, expanded into North Africa, Spain and Sind; the Abbasids (750–1258), who founded Baghdad in 762, presided over a flourishing commercial and intellectual civilization. Historians distinguish conquest from conversion: conquered peoples were not generally forced to convert, and Jews and Christians often lived as protected dhimmis, paying a poll tax (jizya) with restrictions but considerable communal autonomy. Conversion happened gradually over centuries, and many regions did not have Muslim majorities until long after conquest. Later, Islam spread to West Africa, the Indian Ocean and Southeast Asia mainly through traders and Sufi teachers rather than armies. The Mongol sack of Baghdad in 1258 ended the Abbasid caliphate in its classic form.
- 68The Mosque, Friday Prayer and Community LifeThe mosque (masjid, 'place of prostration') is the center of Muslim communal worship. Its key features reflect the needs of prayer: a mihrab, a niche showing the qibla, the direction of Mecca; a minbar, a pulpit from which the Friday sermon (khutba) is given; a large open prayer hall, often carpeted, where worshippers stand in rows shoulder to shoulder; and facilities for ablutions, ritual washing before prayer. Many mosques have a minaret, from which the call to prayer is made. Islam has no ordained priesthood; an imam is a prayer leader chosen for knowledge and character. The Friday noon prayer (jumu'ah) is the main weekly congregational prayer. Because Islam traditionally avoids images of God and prophets in worship, mosque decoration uses calligraphy, geometric patterns and plant motifs. Mosques also serve as schools, community centers and places of charity, and their styles vary from the Great Mosque of Djenné's mud brick to Ottoman domes.
- 69Sufism: The Mystical PathSufism is the mystical dimension of Islam, emphasizing direct, loving experience of God and purification of the heart. Early Sufis such as Rabia al-Adawiyya of Basra (d. 801) taught that God should be loved for God's own sake, not from fear of hell or hope of paradise. Over time Sufis organized into orders (tariqas), each following a chain of teachers traced back to Muhammad and practicing dhikr, the repeated remembrance of God's names, sometimes with music or movement. The poet Jalal al-Din Rumi (1207–1273), whose followers founded the Mevlevi order known for the 'whirling' sema ceremony, wrote verse that remains widely read. Sufis played a major role in spreading Islam to South Asia, Central Asia, Africa and Southeast Asia, often adapting to local cultures, and their shrines became pilgrimage centers. Some Muslim reformers have criticized certain Sufi practices, such as shrine veneration, as innovations, showing ongoing debate within Islam about mysticism.
- 70Islam in Africa and Asia: Mali, the Mughals and IndonesiaIslam's spread beyond the Middle East took many local forms. In West Africa, Muslim merchants crossing the Sahara brought Islam to the courts of Ghana, Mali and Songhai. Mansa Musa of Mali made a famous hajj in 1324, spending so much gold in Cairo that he reportedly depressed its value, and Timbuktu became a center of Islamic scholarship with libraries of manuscripts. In South Asia, Muslim rule culminated in the Mughal Empire (1526–1857); the emperor Akbar (r. 1556–1605) abolished the jizya on non-Muslims and hosted debates among scholars of different faiths, while later rulers such as Aurangzeb pursued more orthodox policies, a contrast historians debate. In Southeast Asia, Islam spread through Indian Ocean trade and Sufi teachers, especially from the 13th century, blending with local traditions in Java and Malaysia. These cases show that Islam became a world civilization by interacting with many cultures, not by a single model.
- 71Ramadan, Eid and the HajjThe Islamic year, based on a 354-day lunar calendar, is marked by major observances. Ramadan, the ninth month, commemorates the beginning of the Quran's revelation; Muslims fast from dawn to sunset, break the fast each evening with a meal called iftar, often beginning with dates and water, and attend extra night prayers. Laylat al-Qadr, the 'Night of Power' in the last ten nights, is considered the holiest night of the year. Ramadan ends with Eid al-Fitr, a festival of prayer, new clothes, family visits and charity (zakat al-fitr) so that the poor can celebrate too. During the hajj in the month of Dhu al-Hijjah, pilgrims wear simple white garments, circle the Kaaba, stand in prayer on the plain of Arafat and recall the story of Abraham, Hagar and Ishmael. Eid al-Adha, the 'Festival of Sacrifice', is celebrated worldwide at the end of the hajj, with meat from sacrificed animals shared with the poor.
- 72Islam in the Modern World: Diversity and DebateIslam is the world's second-largest religion, with roughly 1.9 to 2 billion followers, and the majority live in Asia and Africa rather than the Arab world; the countries with the largest Muslim populations include Indonesia, Pakistan, India and Bangladesh. Since the 19th century, Muslims have debated how to respond to colonialism and modernity. Reformers such as Muhammad Abduh argued that Islam was compatible with reason and science; others emphasized a return to early sources; and the 20th century saw secular nationalism, Islamist political movements, and Iran's 1979 revolution. A small minority of extremist groups have used violence in Islam's name, and their actions have been condemned by most Muslim scholars and organizations. Muslim communities also live as minorities in Europe and the Americas, debating identity, education and religious practice in plural societies. Studying modern Islam requires avoiding stereotypes and recognizing a huge diversity of cultures, sects and views.
- 73Understanding Indigenous ReligionsIndigenous religions are the traditions of peoples rooted in particular lands, from the Arctic to the Amazon, Australia and Africa. There are thousands of them, and scholars warn against lumping them together; yet some common features help outsiders understand them. Many are tied to specific places, such as mountains, rivers and burial grounds, so the land itself is sacred and cannot simply be moved or sold. Knowledge is usually passed on orally, through stories, songs, dances and ceremonies, rather than in written scriptures. Relationships with ancestors, animals and spirits are often central, and religious life is woven into kinship, healing, hunting and farming rather than separated into a distinct sphere. Historically, colonizers and missionaries often labeled these traditions 'primitive', banned ceremonies and removed children to boarding schools. Many communities today are revitalizing languages and rituals, and international law, such as the 2007 UN Declaration on the Rights of Indigenous Peoples, recognizes their right to practice them.
- 74African Traditional Religions: Orisha, Ancestors and CommunityAfrica's traditional religions are diverse, but many share key features. Most recognize a supreme creator, such as Olodumare among the Yoruba or Nyame among the Akan, who is often seen as distant, with everyday religious life focused on intermediary spirits and ancestors. In Yoruba religion of Nigeria and Benin, the orisha, divine beings such as Ogun (iron and technology), Shango (thunder) and Oshun (rivers, love and fertility), are honored through offerings, drumming, dance and possession trance. Ancestors remain part of the community, guiding and protecting descendants who honor them. Diviners, such as Yoruba babalawo using the Ifa system, help people understand problems and choose actions. Religion is closely linked to community, morality and healing rather than individual belief alone. Colonial-era observers often misdescribed these traditions; today they coexist with Christianity and Islam, and many Africans combine elements of both.
- 75African Diaspora Religions: Candomblé, Vodou and SanteríaThe transatlantic slave trade forcibly carried millions of Africans to the Americas, and with them came their religious traditions. Under slavery, Africans were often forced to adopt Christianity and their own practices were banned, yet many preserved them by blending them with Catholicism. In Brazil, Candomblé honors the orixás of Yoruba origin; in Cuba, Santería (also called Regla de Ocha or Lucumí) links orishas with Catholic saints, so that Shango, for example, is associated with Saint Barbara; and in Haiti, Vodou combines West and Central African spirits (lwa) with Catholic elements. Scholars describe this blending as syncretism, though practitioners debate whether it was disguise, genuine fusion or both. Haitian Vodou played a role in the Haitian Revolution, which tradition traces to the Bois Caïman ceremony of 1791. These religions were long stigmatized, and Hollywood stereotypes about 'voodoo' distorted them, but they are now recognized as legitimate living traditions.
- 76Native American Spiritual Traditions and Religious FreedomThe hundreds of Native nations of North America have distinct spiritual traditions, though many share themes of relationship with land, animals and spirit beings, and of balance and reciprocity. The Lakota, for example, practice the Sun Dance and the sweat lodge and speak of Wakan Tanka, the Great Mystery. Pueblo peoples of the Southwest honor katsinam (kachinas), spirit beings represented in ceremonial dances. Many traditions teach that humans have obligations to the natural world. From the late 19th century, US and Canadian governments banned many ceremonies and forced Native children into boarding schools designed to erase languages and religions. Native activists fought for change, and the American Indian Religious Freedom Act of 1978 declared a policy of protecting traditional religions, though it initially lacked enforcement. Later laws addressed the return of sacred objects and ancestral remains (NAGPRA, 1990) and the ceremonial use of peyote. Disputes over sacred sites on federal land continue.
- 77Aboriginal Australian Dreaming and Māori TraditionsAboriginal and Torres Strait Islander peoples have lived in Australia for at least 50,000 to 65,000 years, giving them some of the oldest continuing cultures on Earth. Their spiritual worldview is often called the Dreaming (or Dreamtime in older usage), an English term for concepts expressed differently in hundreds of languages. It refers to the creative era when ancestral beings shaped the land, laws and life, and to the ongoing presence of those beings in country today. Songlines, sung routes that map ancestral journeys across the land, serve as both sacred stories and navigation knowledge, and ceremonies maintain the bond between people and country. In Aotearoa New Zealand, Māori tradition centers on genealogy (whakapapa) linking people to ancestors, gods such as Tāne and Tangaroa, and the land; key concepts include mana (spiritual authority), tapu (sacredness) and the marae as a community meeting place. Both traditions endured colonization and are now strengthened by legal recognition and cultural revival.
- 78Zoroastrianism and the Baha'i FaithTwo smaller traditions show how religions can be ancient or very new, and influential beyond their size. Zoroastrianism, founded by the Iranian prophet Zarathustra (Zoroaster), possibly between about 1500 and 1000 BCE though dates are much debated, teaches worship of one wise creator, Ahura Mazda, and a cosmic struggle between truth (asha) and the lie (druj). Followers pursue 'good thoughts, good words, good deeds', revere fire as a symbol of purity, and believe in judgment after death. It was the faith of Persian empires, and some scholars argue its ideas of a final judgment and heaven and hell influenced Judaism, Christianity and Islam, though this remains debated. After the Arab conquest of Persia, many Zoroastrians migrated to India, where they are known as Parsis. The Baha'i Faith arose in 19th-century Iran with the Bab and Baha'u'llah (1817–1892), teaching the unity of God, of religions and of humanity, including equality of women and men. Baha'is have faced persecution in Iran.
- 79Religion, Law and the Rise of Religious FreedomFor most of history, rulers expected subjects to share their religion, and dissenters could face fines, exile or death. Religious wars after the Reformation pushed Europeans toward compromise: the Edict of Nantes (1598) granted French Protestants limited toleration, and the Peace of Westphalia (1648) ended the Thirty Years' War partly by recognizing the religious choices of rulers. Thinkers such as Roger Williams in colonial Rhode Island and John Locke argued that forced belief was both wrong and impossible. Over time, states developed different models: established churches, as in England; strict separation, as in the US First Amendment; and France's laïcité, set by the 1905 law separating churches and state. Some states today have an official religion or base law partly on religious sources. Article 18 of the Universal Declaration of Human Rights (1948) affirms freedom of thought, conscience and religion, including the right to change religion. Debates continue about how to balance religious freedom with other rights.
- 80Sacred Art and Symbols Across TraditionsReligious art does more than decorate; it teaches, inspires devotion and expresses beliefs that words struggle to capture. Traditions differ in their attitudes to images. Hindu temples overflow with sculpted deities, and Buddhist art developed images of the Buddha and bodhisattvas, often with symbolic hand gestures (mudras). Eastern Orthodox icons are understood as 'windows to heaven', painted according to strict conventions; the Byzantine Iconoclasm controversy (726–843) fought over whether such images were legitimate. Judaism and Islam have generally avoided images of God in worship, so Islamic art developed calligraphy, geometric patterns and arabesques, while Jewish art flourished in illuminated manuscripts and ritual objects. Tibetan mandalas map the cosmos for meditation, and Sikh art centers on the scripture and the Gurus. Studying sacred art as a historical source reveals beliefs, patronage, trade and cultural exchange. Debates over images, from iconoclasm to the Protestant Reformation, show how art itself can become religiously contested.
- 81Faith and Social Reform: Abolition, Civil Rights and Liberation TheologyReligious belief has often motivated movements for social change, though religion has also been used to defend the status quo. Quakers were among the first organized groups to condemn slavery, and evangelical Christians such as William Wilberforce helped lead Britain's abolition campaign, while enslaved people drew on the Exodus story to imagine freedom; at the same time, some churches and theologians defended slavery using scripture. In India, Gandhi combined Hindu ideas with influences from Jainism, Christianity and Tolstoy to develop non-violent resistance. In the United States, Martin Luther King Jr., a Baptist minister, framed the civil rights movement in biblical and Gandhian terms, and Black churches were its organizing hubs. In Latin America, Catholic liberation theology, articulated by Gustavo Gutiérrez in 1971, argued that the church must take a 'preferential option for the poor'. Archbishop Óscar Romero was killed in El Salvador in 1980 after speaking out against repression. These cases show religion's power to inspire reform and the conflicts that follow.
- 82Interfaith Dialogue and Religious ConflictReligious difference has been linked to both conflict and cooperation. Historians note that conflicts labeled 'religious', such as the Thirty Years' War or the Troubles in Northern Ireland, usually also involved politics, land, ethnicity and power, so religion is one factor among several. At the same time, modern movements have built bridges. The 1893 World's Parliament of Religions in Chicago is often seen as the start of organized interfaith dialogue. In 1965 the Catholic Church's declaration Nostra Aetate expressed respect for other religions and rejected blaming Jews collectively for Jesus's death, transforming Catholic–Jewish relations. In 1986 Pope John Paul II invited leaders of many faiths to pray for peace at Assisi, and in 2007 Muslim scholars issued 'A Common Word Between Us and You', inviting Christians to dialogue based on love of God and neighbor. Interfaith work today ranges from theological discussion to joint service projects, showing how communities can cooperate while keeping distinct beliefs.
- 83Secularization and the NonreligiousIn the 20th century, many sociologists predicted that modernization would steadily reduce religion's importance, a theory known as secularization. Evidence is mixed. In Western Europe, Canada, Australia and East Asia, church attendance and religious identification have declined substantially, and in several countries the nonreligious ('nones') form a large share of the population. Yet religion has grown or remained strong in much of Africa, Latin America, South Asia and the Middle East, and higher birth rates in religious communities affect global trends. Some scholars, including Peter Berger, who once championed secularization theory, later argued the world remained 'furiously religious'. The nonreligious are themselves diverse: atheists deny that God exists, agnostics hold that the question cannot be known, and many 'nones' are simply unaffiliated while holding some spiritual beliefs. Understanding these trends helps explain debates over religion in schools, politics and public life.
- 84Comparing World Religions: Shared Questions, Different AnswersComparing religions reveals that they often ask similar questions while answering them differently. All address the nature of ultimate reality: Judaism, Christianity, Islam, Sikhism and Baha'i are monotheistic; many Hindus see one reality in many divine forms; Buddhism and Jainism focus less on a creator; and Confucianism emphasizes ethics and social harmony. Views of time differ, from linear histories moving toward judgment to cycles of rebirth. Goals vary: salvation, moksha, nirvana, harmony with the Dao, or right relationships with ancestors and land. Yet many share ethical principles, such as versions of the Golden Rule found in Confucian, Jewish, Christian, Islamic and Hindu texts, and practices such as prayer, fasting, pilgrimage and rites of passage. Comparison must avoid two errors: claiming all religions are secretly the same, which ignores real differences, or treating them as entirely alien. Respectful comparison builds understanding in a world where people of many faiths and none live side by side.
