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.
Cinema of Slovakia
Given that in the periods from the invention of film in 1896 to 1938 and from 1945 to 1992 Slovakia did not exist as an independent country, there has been some controversy over the naming of certain films as specifically either Slovak or Czech. Although the Czech and Slovak halves of Czechoslovakia each had separate languages, they were close enough for film talent to move freely between the two republics. As a result, during the Czechoslovak period — and even after it — a number of Slovak directors made Czech-language films in Prague, including Juraj Herz and Juraj Jakubisko.
