evidence: Early History: The Ottomans ruled Kosovo for more than four centuries, until Serbia acquired the territory during the First Balkan War in 1912-13. The 20th Century: First partitioned in 1913 between Serbia and Montenegro, Kosovo was then incorporated into the Kingdom of the Serbs, Croats, and Slovenes (later named Yugoslavia) after World War I. During World War II, parts of Kosovo were absorbed into Italian-occupied Albania. After the Italian capitulation, Nazi Germany assumed control over Kosovo until Tito’s Yugoslav Partisans entered at the end of the war. After World War II, Kosovo became an autonomous province of Serbia in the Socialist Federal Republic of Yugoslavia (S.F.R.Y.). The 1974 Yugoslav Constitution gave Kosovo (along with Vojvodina) the status of a Socialist Autonomous Province within Serbia. As such, it possessed nearly equal rights as the six constituent Socialist Republics of the S.F.R.Y.
