(191213) Two military conflicts that deprived the Ottoman Empire of almost all its remaining territory in Europe.
In the First Balkan War, the Balkan League defeated the Ottoman Empire, which, under the terms of the peace treaty (1913), lost Macedonia and Albania. The Second Balkan War broke out after Serbia, Greece, and Romania quarreled with Bulgaria over the division of their joint conquests in Macedonia. Bulgaria was defeated, and Greece and Serbia divided up most of Macedonia between themselves. The wars heightened tensions in the Balkans and helped spark World War I.
