In which year did the First World War started?

The correct answer is 1914.

World War I, commonly referred to as the Great War, was a devastating worldwide conflict that engulfed the world from 1914 to 1918, sparked by the assassination of Archduke Franz Ferdinand of Austria. The war's origins can be traced back to the rising tide of imperialism, nationalism, and militarism that gripped Europe in the late 19th century. Ethnic tensions escalated as colonial powers fought for dominance over the world, drawing nations into the conflict through a complex web of alliances. The First World War began in Europe but quickly escalated, drawing in countries from around the world into a devastating conflict that would claim millions of lives and reshape the global political landscape.
