Podrinje (Serbian Cyrillic: Подриње) is the Slavic name of the Drina river basin, known in English as the Drina Valley. The Drina basin is shared between Bosnia and Herzegovina and Serbia, with majority of its territory being located in Eastern Bosnia, entire Upper Drina course and majority of the Middle course, while the Lower Drina course is shared between two countries,with the river representing border. The part of the Drina basin located in Bosnia and Herzegovina is also called Eastern Bosnia. History Between 1918 and 1922, Podrinje District, with its seat in Šabac, was one of the districts of the Kingdom of Serbs, Croats and Slovenes. The district comprised the north-western part of present-day Šumadija and Western Serbia. Between 1922 and 1929, Podrinje Oblast existed in roughly the same area also with its seat in Šabac. In 1929, a large province of the Kingdom of Yugoslavia known as the Drina Banovina was formed with its capital in Sarajevo. Drina Banovina included western parts of present-day Serbia and eastern parts of present-day Bosnia and Herzegovina. Following World War II Axis occupation in 1941, the province was abolished and its territory was divided between the Independent State of Croatia and the area governed by the Nazi Germany Military Administration in Serbia.

The Republic of Užice was short-lived. German troops occupied the territory again, while the majority of Partisan forces escaped towards Bosnia. During the WWII Genocide of Serbs by the Croatian fascist Ustaše regime, many Serbs were executed along the Drina Valley for months, especially near Višegrad. Jure Francetić's Black Legion killed thousands of defenceless Bosnian Serb civilians and threw their bodies into the Drina river. When the Bosnian War broke out in 1992, the Drina Valley became the focus of a bitter campaign of ethnic cleansing by Army of Republika Srpska forces which eventually culminated in the Srebrenica massacres in July 1995. According to the Sarajevo Research and Documentation Centre (RDC/IDC) Bosnian Atlas of the Dead Project, the Podrinje was the area of Bosnia which suffered the highest number of casualties. In 2007, Mirsad Tokaca, the RDC/IDC's director, reported that 28,666 deaths of a
