WWI: Causes
Nationalism · Imperialism · Militarism · Alliance System · Balkan Tensions
The Architecture of Catastrophe
The outbreak of the First World War in 1914 was not an accident; it was the inevitable detonation of a continent primed for destruction. Decades of unbridled **Militarism**, fierce **Imperial** competition, aggressive **Nationalism**, and a rigid, secret **Alliance system** had transformed Europe into an interconnected powder keg. When a nationalist assassin's bullet struck in the volatile **Balkans**, the diplomatic dominoes fell in exactly 37 days, dragging the world's most advanced empires into an industrial slaughterhouse.

Core Distinctions
The assassination of Archduke Franz Ferdinand was merely the Spark. The Powder Keg was the decades of systemic militarism, imperial rivalry, and rigid alliances (the M.A.I.N. causes) that ensured any local spark would cause a global explosion.
Mobilization vs. Declaration of WarIn 1914, Mobilization (calling up reserves and moving them via trains) was so logistically complex that once ordered, it could not be stopped without throwing the country into chaos. Therefore, mobilization was effectively an act of war, forcing rivals to preemptively strike.
Triple Alliance vs. Triple EntenteThe Triple Alliance (Central Powers base) was Germany, Austria-Hungary, and Italy (though Italy defected in 1915). The Triple Entente (Allied base) was Britain, France, and Russia—a reactionary bloc formed specifically to contain German expansion.
