The dissolution of the
Austro-Hungarian Empire at the close of World War I allowed the Slovaks
to join the closely related Czechs to form Czechoslovakia. Following
the chaos of World War II, Czechoslovakia became a Communist nation
within Soviet-ruled Eastern Europe. Soviet influence collapsed in 1989
and Czechoslovakia once more became free. The Slovaks and the Czechs
agreed to separate peacefully on 1 January 1993. Slovakia joined both
NATO and the EU in the spring of 2004. The primary language is
Slovak; Hungarian is also spoken.
