Yugoslavia occupied a significant portion of the Balkan peninsula, including a strip of land on the east coast of the Adriatic Sea, stretching southward from the Bay of Trieste in Central Europe to the mouth of Bojana as well as Lake Prespa inland, and eastward as far as the Iron Gates on the Danube and Midžor in the Balkan Mountains, thus including a large part of Southeast Europe, a region with a history of ethnic conflict.
