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, with the Slovak Socialist Republic renamed as Slovak Republic. On 17 July 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 31 December 1992.
