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.
Slovakia during World War II
The desire for autonomy was one of the great issues of Slovaks in Czechoslovakia. Josef Tiso and nationalists of the Slovak People's Party pushed for Slovak independence and aligned themselves with the National Socialist Party in Germany. On March 13, 1939 Hitler invited Tiso to Berlin. Hitler would support him if he separated Slovakia from Czechoslovakia or the Slovakia territory will be divided under Hungary, Czech Republic and Poland. On March 14, 1939 Slovakia declared independence, calling itself the Slovak Republic. German troops soon occupied Bohemia and Moravia.
