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.
Origins of Czechoslovakia
On May 31, 1918, Czech and Slovak representatives in the United States signed the Pittsburgh Agreement endorsing a plan for a unified Czecho-Slovak state in which Slovakia would have its own assembly. In early October 1918, Germany and Austria proposed peace negotiations. On October 18, while in the United States, Masaryk issued a declaration of Czechoslovak independence. Masaryk insisted that the new Czechoslovak state include the historic Bohemian Kingdom, containing the German-populated borderland. On October 21, however, German deputies from Bohemia joined other German and Austrian deputies in the Austrian parliament in declaring an independent German-Austrian state. Following the abdication of Charles I on November 11, Czech troops took control of borderlands.
