World War I: The Great War

World War I, also known as The Great War, took place from 1914 to 1918 and involved many of the world's great powers at the time. The war was ignited by the assassination of Archduke Franz Ferdinand of Austria-Hungary, which led to a complex web of alliances being activated.

The conflict was characterized by trench warfare and the use of new military technologies, leading to unprecedented levels of destruction and loss of life. The war concluded with the Treaty of Versailles in 1919, which imposed heavy reparations on Germany and redrew national boundaries in Europe.
