World War I, often referred to as The Great War, occurred from 1914 to 1918 and involved many of the world's major powers. The conflict was primarily triggered by the assassination of Archduke Franz Ferdinand of Austria, leading to a complex web of alliances being activated. The war saw trench warfare, significant loss of life, and the introduction of new military technologies such as tanks and chemical weapons.
