Balkan Wars, 1912–13, two short wars, fought for the possession of the European territories of the Ottoman Empire. The outbreak of the Italo-Turkish War for the possession of Tripoli (1911) encouraged the Balkan states to increase their territory at Turkish expense. Serbia and Bulgaria accordingly concluded (1912), with the aid of Russian secret diplomacy, a treaty of alliance. In a secret annex, the treaty provided for joint military action and the division of prospective conquests. The outbreak of the war (Oct., 1912), in which Greece and Montenegro joined the original allies, was followed by the speedy expulsion of the Turks from all of European Turkey, except the Constantinople area. After the conclusion of hostilities Serbia showed intentions of annexing a large part of Albania, in order to gain an outlet on the Adriatic, but this step toward a
was opposed by Austria-Hungary and Italy and by the Albanians, who had proclaimed their independence. Conferences of the ambassadors of the Great Powers at London created (1913) an independent Albania of fair size, thus cutting Serbia off from the sea. Dissatisfied with these terms, Serbia demanded of Bulgaria a greater share of Macedonia. Bulgaria thereupon attacked (June, 1913) Serbia, only to be attacked by Romania, Greece, and Turkey. As a result of this Second Balkan War, Bulgaria lost territory to all her enemies by the Treaty of Bucharest (Aug., 1913). The Balkan Wars prepared the way for World War I by satisfying some of the aspirations of Serbia and thereby giving a great impetus to the Serbian desire to annex parts of Austria-Hungary; by alarming Austria and stiffening Austrian resolution to crush Serbia; and by giving causes of dissatisfaction to Bulgaria and Turkey.
