1918–1923: Different systems in former Austrian territory (Bohemia, Moravia, a small part of Silesia) compared to former Hungarian territory (Slovakia and Ruthenia): three lands (země) (also called district units (kraje)): Bohemia, Moravia, Silesia, plus 21 counties (župy) in today's Slovakia and three counties in today's Ruthenia; both lands and counties were divided into districts (okresy). 1923–1927: As above, except that the Slovak and Ruthenian counties were replaced by six (grand) counties ((veľ)župy) in Slovakia and one (grand) county in Ruthenia, and the numbers and boundaries of the okresy were changed in those two territories. 1928–1938: Four lands (Czech: země, Slovak: krajiny): Bohemia, Moravia-Silesia, Slovakia and Sub-Carpathian Ruthenia, divided into districts (okresy). Late 1938 – March 1939: As above, but Slovakia and Ruthenia gained the status of "autonomous lands". Slovakia was called Slovenský štát, with its own currency and government. 1945–1948: As in 1928–1938, except that Ruthenia became part of the Soviet Union. 1949–1960: 19 regions (kraje) divided into 270 okresy. 1960–1992: 10 kraje, Prague, and (from 1970) Bratislava (capital of Slovakia); these were divided into 109–114 okresy; the kraje were abolished temporarily in Slovakia in 1969–1970 and for many purposes from 1991 in Czechoslovakia; in addition, the Czech Socialist Republic and the Slovak Socialist Republic were established in 1969 (without the word Socialist from 1990).
