The Inca Empire

The Inca Empire, which thrived in the Andean region of South America from the early 15th century until the Spanish conquest in the 1530s, was known for its sophisticated political system, extensive road networks, and remarkable architectural achievements, including Machu Picchu. The Incas utilized advanced agricultural techniques such as terrace farming and irrigation to adapt to their mountainous environment. Their society was organized into a highly structured hierarchy, with the Sapa Inca at the top, believed to be a descendant of the sun god. The empire's fall came swiftly with the arrival of Spanish Conquistadors, leading to dramatic cultural and demographic changes.
