For the young folk, copied directly from Ms Wiki of course, just like you should not write your term papers:
“Czechoslovakia was a sovereign state in Central Europe which existed from October 1918, when it declared its independence from the Austro-Hungarian Empire (at the end of World War I and as part of the Treaty of St. Germain), until 1992.
“From 1939 to 1945, the state did not de facto exist because of its forced division and partial incorporation into Nazi Germany, but the Czechoslovak government-in-exile operated independently during this period. In 1945, the eastern part of Carpathian Ruthenia was taken over by the Soviet Union.
“On 1 January 1993, Czechoslovakia peacefully split into the Czech Republic and Slovakia.”
