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.
Regions of Slovakia
In 1928–1939 (and formally also 1945–1948) Slovakia as a whole formed the administrative unit "Slovak land" ("Krajina slovenská") within Czechoslovakia.Each kraj was named after its principal city.Note: The "kraje" were abolished from July 1, 1969 to December 28, 1970 and reintroduced then.
