question: How long did the Ottomans control the Balkans?
article: Balkan Wars
candidates: The Balkan Wars were two conflicts that took place in the Balkan Peninsula in south-eastern Europe in 1912 and 1913. Four Balkan states defeated the Ottoman Empire in the first war; one of the four, Bulgaria, was defeated in the second war. The Ottoman Empire lost nearly all of its holdings in Europe. Austria-Hungary, although not a combatant, was weakened as a much enlarged Serbia pushed for union of the South Slavic peoples. The war set the stage for the Balkan crisis of 1914 and thus was a "prelude to the First World War. "By the early 20th century, Bulgaria, Greece, Montenegro and Serbia had achieved independence from the Ottoman Empire, but large elements of their ethnic populations remained under Ottoman rule. In 1912, these countries formed the Balkan League. There were three main causes of the First Balkan War. The Ottoman Empire was unable to reform itself, govern satisfactorily, or deal with the rising ethnic nationalism of its diverse peoples. Secondly the Great Powers quarreled amongst themselves and failed to ensure that the Ottomans would carry out the needed reforms. This led the Balkan states to impose their own solution. Most important, the Balkan League had been formed, and its members were confident that it could defeat the Turks. The Ottoman Empire lost almost all its European territories to the west of the River Maritsa, drawing present day Turkey's western border. A large influx of Turks started to flee into the Ottoman heartland as a result of the lost lands. By 1914, the remaining core region of the Ottoman Empire had experienced a population increase of around 2.5 million because of the flood of immigration from the Balkans. In Turkey, it is considered a major disaster ("Balkan harbi faciası") in the nation's history. The unexpected fall and sudden relinquishing of Turkish-dominated European territories created a psycho-traumatic event amongst the Turks that is said to have triggered the ultimate collapse of the empire itself within five years. Nazım Pasha, the chief of staff of the Ottoman army has been held responsible of the failure and was assassinated in 1913 by Young Turks. The First Balkan War broke out when the League attacked the Ottoman Empire on 8 October 1912 and was ended seven months later by the Treaty of London. After five centuries, the Ottoman Empire lost virtually all of its possessions in the Balkans. The Second Balkan War broke out on 16 June 1913. Bulgaria was dissatisfied over the division of the spoils in Macedonia, made in secret by its former allies, Serbia and Greece, and attacked them. The Serbian and Greek armies repulsed the Bulgarian offensive and counter-attacked into Bulgaria, while Romania and the Ottoman Empire also attacked Bulgaria and gained (or regained) territory. In the resulting Treaty of Bucharest, Bulgaria lost most of the territories it had gained in the First Balkan War.
