The decline of the Ottoman Empire led the Balkan League - an alliance of Bulgaria, Serbia, and Greece - to declare war on Turkey in 1912 in an attempt to capture territory and force the Turks out of the region. The war ended a year later with the signing of the Treaty of London, which split Turkey's European holdings among the Balkan allies. Disputes over the division of territory soon led to the dissolution of the Balkan League and the Second Balkan War.
