The dissolution of Austria-Hungary was a major geopolitical event that occurred as a result of the growth of internal social contradictions and the separation of different parts of Austria-Hungary. The more immediate reasons for the collapse of the state were World War I, the 1918 crop failure, general starvation and the economic crisis.[citation needed] The Austro-Hungarian Empire had additionally been weakened over time by a widening gap between Hungarian and Austrian interests.[2] Furthermore, a history of chronic overcommitment rooted in the 1815 Congress of Vienna in which Metternich pledged Austria to fulfill a role that necessitated unwavering Austrian strength and resulted in overextension.[2] Upon this weakened foundation, additional stressors during World War I catalyzed the collapse of the empire. The 1917 October Revolution and the Wilsonian peace pronouncements from January 1918 onward encouraged socialism on the one hand, and nationalism on the other, or alternatively a combination of both tendencies, among all peoples of the Habsburg monarchy.[3]
The remaining territories inhabited by divided peoples fell into the composition of existing or newly formed states. Legally, the collapse of the empire was formalized in the September 1919 Treaty of Saint-Germain-en-Laye with Austria, which also acted as a peace treaty after the First World War, and in the June 1920 Treaty of Trianon with Hungary. Later on, a lot of Austrian and Hungarian lands were ceded to other countries.
