How did the war start because of the rise of the nations?

Answer 1

The war was largely ignited by the rise of nationalism, as various ethnic groups sought self-determination and independence from empires. This surge in national pride created tensions, particularly in regions like the Balkans, where competing national interests clashed. Additionally, the formation of alliances and militarization among European powers further escalated these conflicts, ultimately leading to a wider war. The assassination of Archduke Franz Ferdinand in 1914 acted as a catalyst, triggering these underlying nationalistic tensions into open conflict.
