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.
WallachiaWallachia or Walachia (wɒ'leɪkiə; Țara Românească, ˈt͡sara romɨˈne̯askə; archaic: Țeara Rumânească, Romanian Cyrillic alphabet: Цѣра Рꙋмѫнѣскъ) is a historical and geographical region of Romania. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia is traditionally divided into two sections, Muntenia (Greater Wallachia) and Oltenia (Lesser Wallachia). Dobruja could sometimes be considered a third section due to its proximity and brief rule over it.
