context_page_description: Slavonia is, with Dalmatia, Croatia proper and Istria, one of the four historical regions of Croatia. Taking up the east of the country, it roughly corresponds with five Croatian counties: Brod-Posavina, Osijek-Baranja, Požega-Slavonia, Virovitica-Podravina and Vukovar-Syrmia, although the territory of the counties includes Baranya, and the definition of the western extent of Slavonia as a region varies. The counties cover 12,556 square kilometres or 22.2% of Croatia, inhabited by 806,192—18.8% of Croatia's population. The largest city in the region is Osijek, followed by Slavonski Brod and Vinkovci.
  Slavonia is located in the Pannonian Basin, largely bordered by the Danube, Drava and Sava rivers. In the west, the region consists of the Sava and Drava valleys and the mountains surrounding the Požega Valley, and plains in the east. Slavonia enjoys a moderate continental climate with relatively low precipitation.
  After the fall of the Western Roman Empire, which ruled the area of modern-day Slavonia until the 5th century, Ostrogoths and Lombards controlled the area before the arrival of Avars and Slavs, when the Principality of Lower Pannonia was established in the 7th century.
context_section_description: The Croatian counties were re-established in 1992, but their borders changed in some instances, with the latest revision taking place in 2006. Slavonia consists of five counties—Brod-Posavina, Osijek-Baranja, Požega-Slavonia, Virovitica-Podravina and Vukovar-Srijem counties—which largely cover the territory historically associated with Slavonia. The western borders of the five-county territory lie in the area where the western boundary of Slavonia generally has been located since the Ottoman conquest, with the remaining borders being at the international borders of Croatia. This places the Croatian part of Baranya into the Slavonian counties, constituting the Eastern Croatia macroregion. Terms Eastern Croatia and Slavonia are increasingly used as synonyms. The Brod-Posavina County comprises two cities—Slavonski Brod and Nova Gradiška—and 26 Municipalities of Croatia. The Osijek-Baranja County consists of seven cities—Beli Manastir, Belišće, Donji Miholjac, Đakovo, Našice, Osijek and Valpovo—and 35 municipalities. The Požega-Slavonia County comprises five cities—Kutjevo, Lipik, Pakrac, Pleternica and Požega—and five municipalities. The Virovitica-Podravina County covers three cities—Orahovica, Slatina and Virovitica—and 13 municipalities. The Vukovar-Srijem County encompasses five cities—Ilok, Otok, Vinkovci, Vukovar and Županja—and 26 municipalities. The whole of Slavonia is the eastern half of Central and Eastern (Pannonian) Croatia NUTS-2 statistical unit of Croatia, together with further areas of Central Croatia. Other statistical units correspond to the counties, cities and municipalities. The five counties combined cover area size of 12,556 square kilometres (4,848 square miles), representing 22.2% of territory of Croatia.
