Republic was proclaimed. It included northern parts of Baranya and Ba?ka regions, which were assigned to Hungary by the treaty. On August 21�25, 1921, the Republic was abolished and its territory was included into Hungary, as was previously decided by the Treaty of Trianon. The northern part of Baranya in Hungary was included into Baranya county.
The southern (Yugoslav) part of the region was part of Novi Sad county between 1918 and 1922, part of Ba?ka Oblast between 1922 and 1929, and in 1929 it was included into the Danube Banovina, a province of the Kingdom of Yugoslavia. In 1941, the Yugoslav Baranya was occupied by Hungary, but it was returned to Yugoslavia in 1944. In 1944-1945, Yugoslav Baranya was part of the Autonomous Province of Vojvodina, while in 1945 it was assigned to the People's Republic of Croatia.
During the War in Croatia in 1991 it came under control of the SAO Eastern Slavonia, Baranja and Western Srem, which became part of the Republic of Serbian Krajina. After the war ended (in 1995), it was peacefully integrated into Croatia in 1998, by the Erdut Agreement. According to the agreement, it was administered by the administration of the United Nations from 1996 to 1998, when it was returned to full sovereignty of Croatia. Today, it is part of that republic's Osijek-Baranja county
