 The traditional division of the country into counties was abolished in the 1920s, when the Kingdom of Serbs, Croats and Slovenes and the subsequent Kingdom of Yugoslavia introduced oblasts and banovinas respectively.Communist-ruled Croatia, as a constituent part of post-WWII Yugoslavia, abolished earlier divisions and introduced (mostly rural) municipalities, subdividing Croatia into approximately one hundred municipalities.Counties were reintroduced in 1992 by legislation, significantly altered in terms of territory relative to the pre-1920s subdivisions—for instance, in 1918 the Transleithanian part of Croatia was divided into eight counties with their seats in Bjelovar, Gospić, Ogulin, Požega, Vukovar, Varaždin, Osijek and Zagreb, while the 1992 legislation established 14 counties in the same territory.
