Balkan Wars

(1912–13) 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.

      (1912–13), two successive military conflicts that deprived the Ottoman Empire of almost all its remaining territory in Europe.

      The First Balkan War was fought between the members of the Balkan League—Serbia, Bulgaria, Greece, and Montenegro—and the Ottoman Empire. The Balkan League was formed under Russian auspices in the spring of 1912 to take Macedonia away from Turkey, which was already involved in a war with Italy. The league was able to field a combined force of 750,000 men. Montenegro opened hostilities by declaring war on Turkey on Oct. 8, 1912, and the other members of the league followed suit 10 days later.

      The Balkan allies were soon victorious. In Thrace, the Bulgarians defeated the main Ottoman forces, advancing to the outskirts of Constantinople (now Istanbul) and laying siege to Adrianople (Edirne). In Macedonia, the Serbian army achieved a great victory at Kumanovo that enabled it to capture Bitola and to join forces with the Montenegrins and enter Skopje. The Greeks, meanwhile, occupied Salonika (Thessaloníki) and advanced on Ioánnina. In Albania, the Montenegrins besieged Shkodër, and the Serbs entered Durrës.

      The Turkish collapse was so complete that all parties were willing to conclude an armistice on Dec. 3, 1912. A peace conference was begun in London, but after a coup d'état by the Young Turks in Constantinople in January 1913, war with the Ottomans was resumed. Again the allies were victorious: Ioánnina fell to the Greeks and Adrianople to the Bulgarians. Under a peace treaty signed in London on May 30, 1913, the Ottoman Empire lost almost all of its remaining European territory, including all of Macedonia and Albania. Albanian independence was insisted upon by the European powers, and Macedonia was to be divided among the Balkan allies.

      The Second Balkan War began when Serbia, Greece, and Romania quarreled with Bulgaria over the division of their joint conquests in Macedonia. On June 1, 1913, Serbia and Greece formed an alliance against Bulgaria, and the war began on the night of June 29/30, 1913, when King Ferdinand of Bulgaria ordered his troops to attack Serbian and Greek forces in Macedonia. The Bulgarians were defeated, however, and a peace treaty was signed between the combatants on Aug. 10, 1913. Under the terms of the treaty, Greece and Serbia divided up most of Macedonia between themselves, leaving Bulgaria with only a small part of the region.

      As a result of the Balkan Wars, Greece gained southern Macedonia as well as the island of Crete. Serbia gained the Kosovo region and extended into northern and central Macedonia. Albania was made an independent state under a German prince. The political consequences of the wars were considerable. Bulgaria, frustrated in Macedonia, looked to Austria for support, while Serbia, which had been forced by Austria to give up its Albanian conquests, regarded Vienna with greater hostility than ever. The heightened tensions in the Balkans reached their climax in World War I, which was sparked by the assassination of the Austrian heir-apparent by a Serb in Sarajevo, Bosnia, on June 28, 1914.
