The Dissolution of Czechoslovakia (Czech: Rozdělení Československa, Slovak: Rozdelenie Česko-Slovenska), 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.
It is sometimes known as the Velvet Divorce, a reference to the bloodless Velvet Revolution of 1989 that led to the end of the rule of the Communist Party of Czechoslovakia and the restoration of a capitalist state in the country.My italics. Fascinating stuff. It is strange that it sounds almost eccentric for two peoples to be able to split amicably without feeling the need to bomb or shoot each other.
Czechoslovakia is the only former socialist state to have an entirely peaceful breakup.
