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.
History of Slovakia
The victorious Powers restored Czechoslovakia in 1945 in the wake of World War II, albeit without the province of Ruthenia, which Prague ceded to the Soviet Union. The Beneš decrees, adopted as a result of the events of the war, led to disenfranchisement and persecution of the Hungarian minority in southern Slovakia. (The affected Hungarians regained Czechoslovak citizenship in 1948.)
