1912 – 1913
Two successive wars fought across the Balkan Peninsula that ended five centuries of Ottoman rule in Europe and reshaped the region's borders in less than a year. In the First Balkan War (October 1912–May 1913), Bulgaria, Serbia, Greece, and Montenegro united as the Balkan League and routed the Ottoman Empire from nearly all its European territories. In the Second Balkan War (June–August 1913), Bulgaria turned on its former allies in a dispute over the division of Macedonia, was defeated by Serbia, Greece, Romania, and a resurgent Ottoman force, and suffered what Bulgarians called the 'Second National Catastrophe.' The wars created Albania, redrew the map of southeastern Europe, sowed the seeds of Bulgarian revanchism that would pull Sofia into the Central Powers in WWI, and set the stage for the assassination in Sarajevo that ignited the Great War.
