Dissolution of Czechoslovakia
The Dissolution of Czechoslovakia (, ), which took effect on 1 January 1993, was an event that saw the self-determined split of the federal state of Czechoslovakia into the Czech Republic and Slovakia, entities that had arisen before as the "Czech Socialist Republic" and the "Slovak Socialist Republic" in 1969 within the framework of a federal republic.
Czech and Slovak Federative Republic
After the fall of communism in 1989, Czechoslovakia adopted the official name Czech and Slovak Federative Republic (, ; ČSFR) during the period from 23 April 1990 until 31 December 1992, when the country was dissolved into the Czech Republic and Slovakia. This period is also referred to as the Fifth Czechoslovak Republic.
