Treaty of Saint-Germain-en-Laye

The 1919 peace treaty between the Allied powers and the Republic of Austria that formally dissolved the Habsburg monarchy and set Austria’s postwar borders and obligations.

Dissolution of Austria-Hungary: The breakup of the Habsburg monarchy into successor states at the end of the First World War. The treaty gave legal form to the monarchy’s dissolution and recognized several successor states.
League of Nations: An international organization founded in 1920 to promote cooperation and prevent war. Its consent was required for Austria to alter the treaty’s restrictions on union with Germany.
Paris Peace Conference: The 1919–1920 negotiations that established postwar settlements after the First World War. The Allied powers negotiated Austria’s peace terms within this wider conference.
Treaty of Neuilly-sur-Seine: The 1919 peace treaty between the Allied powers and Bulgaria after the First World War. It was the contemporaneous settlement for another defeated state, with different territorial provisions.
Austria–Hungary border: The international boundary separating Austria and Hungary after the dissolution of the Habsburg monarchy. The treaty fixed Austria’s borders, including its eastern boundary with Hungary.
Austrian Armed Forces: The military forces maintained by the Republic of Austria. The treaty restricted Austria’s army to a small professional force and prohibited conscription.
Armistice of Villa Giusti: The 1918 armistice between Austria-Hungary and Italy that ended fighting on the Italian front. It preceded the treaty and left Austria seeking a formal peace settlement.
Treaty of Sèvres: The 1920 peace treaty between the Allied powers and the Ottoman Empire after the First World War. Its attempted partition of the Ottoman Empire contrasted with Austria’s territorial settlement.
Anschluss: The proposed or actual union of Austria with Germany, especially the 1938 annexation by Nazi Germany. The treaty prohibited Austria from uniting with Germany without League of Nations consent.
War reparations: Payments or other compensation demanded from a state for damage caused by war. The treaty established Austria’s liability for reparations, though its weakened economy limited payment.
