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 Czechoslovakia
On 14 March 1939, the Slovak State declared its independence as a satellite state under Jozef Tiso. Hitler forced Hácha to surrender what remained of Bohemia and Moravia to German control on 15 March 1939, establishing the German Protectorate of Bohemia and Moravia. On the same day, the Carpatho-Ukraine (Subcarpathian Ruthenia) declared its independence and was immediately invaded and annexed by Hungary. Finally, on 23 March, Hungary invaded and occupied some further parts of eastern Slovakia from Carpatho-Ukraine.
