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.
Martin Declaration
The Martin Declaration () is the name usually given to the "Declaration of the Slovak Nation" () that was proclaimed in the town of Turčiansky Svätý Martin (now Martin, Slovakia) on 30 October 1918. The declaration was effectively a declaration of independence from the Kingdom of Hungary (within the Austro-Hungarian Empire) and presaged Slovakia's unification with the Czech lands as part of the new state of Czechoslovakia.
