Relating to Czechoslovakia, a former European country that existed from 1918 to 1992 before splitting into the Czech Republic and Slovakia.
From Czechoslovakia, a compound of 'Czech' (from Bohemia's native name) and 'Slovak' (from the Slovaks, a Slavic people). The country was formed after World War I from territories of the Austro-Hungarian Empire.
Czechoslovakia's split into two countries in 1993 (called the 'Velvet Divorce') was one of history's most peaceful national separations—so peaceful that Czechoslovakian is now mostly a historical term rather than something used to describe present-day people.
