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.
Tanks of Czechoslovakia
After the first World War, Slovakia and the regions of Bohemia, Moravia, Silesia and Carpathian Ruthenia formed a common state, Czechoslovakia, with the borders confirmed by the Treaty of Saint Germain and Treaty of Trianon. In 1919, during the chaos following the breakup of Austria-Hungary, Czechoslovakia was formed with numerous Germans and Hungarians within the newly set borders. A Slovak patriot Milan Rastislav Štefánik (1880–1919), who helped organize Czechoslovak regiments against Austria-Hungary during the First World War, died in a plane crash. In the peace following the World War, Czechoslovakia emerged as a sovereign European state. It provided what were at the time rather extensive rights to its minorities and remained the only democracy in this part of Europe in the interwar period.
