The dissolution of Czechoslovakia, which took effect on 31 December 1992, was the self-determined partition of the federal republic of Czechoslovakia into the independent countries of the Czech Republic and Slovakia. Both mirrored the Czech Socialist Republic and the Slovak Socialist Republic, which had been created in 1969 as the constituent states of the Czechoslovak Socialist Republic until the end of 1989.
It is sometimes known as the Velvet Divorce, a reference to the bloodless Velvet Revolution of 1989, which had led to the end of the rule of the Communist Party of Czechoslovakia. The dissolution of Czechoslovakia is clearly linked to the end of the Cold War and the dissolution of other Eastern Bloc countries such as the Dissolution of the Soviet Union and the Breakup of Yugoslavia. Unlike Yugoslavia, which was also created in 1918 and disappeared in 1992, Czechoslovakia did not experience violent clashes due to nationalism, which in the case of Yugoslavia led to the Yugoslav Wars.
