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 Socialist Republic
The Czech Socialist Republic ("Česká socialistická republika" in Czech; abbreviated ČSR) was a republic within the Czechoslovak Socialist Republic that is now the independent Czech Republic. The name was used from 1 January 1969 to March 1990.
