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.
Martin Declaration
The Martin Declaration () is the name usually given to the "Declaration of the Slovak Nation" () that was proclaimed in the town of Turčiansky Svätý Martin (now Martin, Slovakia) on 30 October 1918. The declaration was effectively a declaration of independence from the Kingdom of Hungary (within the Austro-Hungarian Empire) and presaged Slovakia's unification with the Czech lands as part of the new state of Czechoslovakia.
