context_section_description: 1918–1923: different systems based on former Austrian territories (Kingdom of Bohemia, Margraviate of Moravia, and Duchy of Upper and Lower Silesia) and former Hungarian counties in the north (later forming Slovakia (21 counties) and Subcarpathian Ruthenia (4 counties)) were reorganized into three provinces (Czech: země, Slovak: krajiny – literally "lands") of Bohemia-Moravia-Silesia, 21 counties (župy) of Slovakia, and 4 counties of Subcarpathian Ruthenia (today's Zakarpattia Oblast in Ukraine); all provinces and counties were further divided into districts (okresy)
  1923–1927: like above, except that the above counties were replaced by 6 (grand) counties ((veľ)župy) in Slovakia and 1 (grand) county in Subcarpathian Ruthenia, and the number and frontiers of districts were changed on these two territories
  1928–1938: 4 provinces: Bohemia, Moravia-Silesia, Slovakia and Subcarpathian Ruthenia; divided into districts
  late 1938–March 1939: like above, but Slovakia and Subcarpathian Ruthenia were promoted to "autonomous lands", while the border regions were ceded to Germany (so-called Sudetenland) and Hungary (southern parts of Slovakia and Subcarpathian Ruthenia)
  1939–1945: Bohemia and Moravia became the protectorate Germany, the remainder of Subcarpathian Ruthenia annexed by Hungary, while Slovakia was nominally independent
  1945–1948: like 1928–1938, except that Subcarpathian Ruthenia became part of the Soviet Union in 1945
  1949–1960: 19 regions divided in 270 districts; Czech historical provinces/lands abolished
  1960–1992: see above
