Bucharest, Treaty of (1913), was the peace agreement ending the Second Balkan War. The Second Balkan War began with a Bulgarian attack on the Greeks and Serbians on the night of June 29-30, 1913. In July, Romania and the Ottoman Empire joined the Greeks, Montenegrins, and Serbians. On July 21, Bulgaria asked for a truce. The Treaty of Bucharest was signed on Aug. 10, 1913.
Under the treaty, Bulgaria lost much of the territory that it had taken from the Ottoman Empire in the First Balkan War (1912-1913), in which Bulgaria, Greece, Montenegro, and Serbia had joined forces to drive the Ottomans out of Europe. The Ottoman Empire had lost nearly all of its territory in Europe, but the victorious countries argued over the division of the lands they had won.
Bulgaria kept only western Thrace and a small corner of eastern Macedonia. The rest of Macedonia was divided among Serbia and Greece. The Ottomans seized Adrianople, with all of eastern Thrace.
The peace settlement left Europe with new problems and a general uneasiness regarding the Balkans. Serbia’s increased prestige encouraged the Slavs of Austria-Hungary to renew their efforts for independence.
