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.
Slovakia
The end of Communist rule in Czechoslovakia in 1989, during the peaceful Velvet Revolution, was followed once again by the country's dissolution, this time into two successor states. The word "socialist" was dropped in the names of the two republics, i.e. the Slovak Socialist Republic was renamed Slovak Republic. In July 17, 1992 Slovakia, led by Prime Minister Vladimír Mečiar, declared itself a sovereign state, meaning that its laws took precedence over those of the federal government. Throughout the autumn of 1992, Mečiar and Czech Prime Minister Václav Klaus negotiated the details for disbanding the federation. In November the federal parliament voted to dissolve the country officially on December 31, 1992.
