What were the 4 reasons world war 1 became a world war?

Answer 1

World War I became a world war due to a combination of factors: the complex system of alliances that entangled major powers, including the Triple Entente and the Triple Alliance, which escalated regional conflicts into a global war. Nationalism heightened tensions as countries sought to assert their dominance, while militarism led to an arms race that prepared nations for large-scale conflict. Additionally, imperial ambitions fueled competition over colonies and resources. Finally, the assassination of Archduke Franz Ferdinand acted as the catalyst that triggered these underlying tensions into a full-scale war.
