Dissolution of Czechoslovakia
The Dissolution of Czechoslovakia (, ), which took effect on 1 January 1993, was an event that saw the self-determined split of the federal state of Czechoslovakia into the Czech Republic and Slovakia, entities that had arisen before as the "Czech Socialist Republic" and the "Slovak Socialist Republic" in 1969 within the framework of a federal republic.
Czech Republic
The remaining Czech territory was occupied by Germany, which transformed it into the so-called Protectorate of Bohemia and Moravia. The protectorate was proclaimed part of the Third Reich, and the president and prime minister were subordinated to the Nazi Germany's "Reichsprotektor". Subcarpathian Rus declared independence as the Republic of Carpatho-Ukraine on 15 March 1939 but was invaded by Hungary the same day and formally annexed the next day. Approximately 345,000 Czechoslovak citizens, including 277,000 Jews, were killed or executed while hundreds of thousands of others were sent to prisons and Nazi concentration camps or used as forced labor. Up to two-thirds of the citizens were in groups targeted by the Nazis for deportation or death. One concentration camp was located within the Czech territory at Terezín, north of Prague. The Nazi "Generalplan Ost" called for the extermination, expulsion, Germanization or enslavement of most or all Czechs for the purpose of providing more living space for the German people.
