Czechoslovakia

Czechoslovakia, or Czecho-Slovakia (Czech and Slovak: Československo, Česko-Slovensko), was a sovereign state in Central Europe that existed from October 1918, when it declared its independence from the Austro-Hungarian Empire, until its peaceful dissolution into the Czech Republic and Slovakia on 1 January 1993. From 1939 to 1945, following its forced division and partial incorporation into Nazi Germany, the state did not de facto exist but its government-in-exile continued to operate. From 1948 to 1990, Czechoslovakia was part of the Eastern Bloc. https://en.wikipedia.org/wiki/Czechoslovakia
