World War I was ignited by a complex interplay of factors including militarism, alliances, imperialism, and nationalism. Militarism led to aggressive military preparations, culminating in massive army drafts. Europe was divided into the Triple Alliance and Triple Entente, escalating tensions. Imperialistic ambitions caused fierce competition for colonies, while nationalism fueled desires for independence, notably in Serbia. The assassination of Archduke Franz Ferdinand triggered the conflict. Austria-Hungary's declaration of war on Serbia in July 1914 set in motion a series of declarations that engulfed the world in war.
