Dissolution of Czechoslovakia
Since the federalization in 1968, Czechoslovakia had divided citizenship, either of the Czech Socialist Republic or of the Slovak Socialist Republic (the word 'Socialist' was dropped from both names shortly after the Velvet Revolution). This distinction, however, had little effect on the citizen's life. On January 1, 1993, all Czechoslovak citizens automatically became citizens either of the Czech Republic or the Slovak Republic, based on their previous citizenship, permanent residence address, birthplace, family ties, job, and other criteria. Additionally, people had one year's time to claim the other citizenship under certain conditions.
Czech and Slovak Federative Republic
After the fall of communism in 1989, Czechoslovakia adopted the official name Czech and Slovak Federative Republic (, ; ČSFR) during the period from 23 April 1990 until 31 December 1992, when the country was dissolved into the Czech Republic and Slovakia. This period is also referred to as the Fifth Czechoslovak Republic.
