This article deals with historic administrative divisions of Czechoslovakia up to 1992, when the country was split into the Czech Republic and Slovakia and the divisions were changed.
For the current divisions of those two countries, see their main articles and the articles Regions of Slovakia and Regions of the Czech Republic.
The country consisted of 10 Regions ('kraje'), Prague, and (since 1970) Bratislava; further divided in 109–114 districts ('okresy').
The kraje were abolished temporarily in Slovakia in 1969–1970 and since late 1990 in whole Czechoslovakia. In addition, the two republics Czech Socialist Republic and Slovak Socialist Republic were established in 1969 (without the word Socialist since 1990).
Since many regions changed significantly after the split in 1993, here is list of their original names and current regions they approximately correspond to:
