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.
Hungary–Slovakia relations
Hungary and Slovakia are two neighboring countries in Central Europe. There are two major periods of official foreign relations between them in contemporary history. The first period included relations between the Kingdom of Hungary and the first Slovak Republic in 1939-1945. The second period has started in 1993, when the countries again established diplomatic relations, the year when Slovakia became independent of Czechoslovakia. Hungary has an embassy in Bratislava and a general consulate in Košice ("Hungarian": Kassa), and Slovakia has an embassy in Budapest and a general consulate in Békéscsaba.
