SlavoniaSlavonia (sləˈvoʊniə; Slavonija) 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 or 22.2% of Croatia, inhabited by 806,192—18.8% of Croatia's population.
