Czechoslovakia was a country in Eastern Europe that existed from 1918-1992. While Czechoslovakia existed the country suffered decades of oppression after a brief period of freedom between World War I and World War II.
Czechoslovakia was formed after the Austro-Hungarian Empire broke up at the end of World War I and succeeded in staying democratic when many other newly formed European countries became Dictatorships. This lasted until it was annexed by Germany in 1938. In 1948 Czechoslovakia became a Socialist Republic.
The people of Czechoslovakia voted to divide into two separate nations in 1992. They are now the Czech Republic and Slovakia. Both parts of former Czechoslovakia are now democratic, both are members of the European Union and their economies are developing successfully.
