After the fall of the Berlin Wall, which nation broke up into many independent states?

Communism was abandoned in Albania and Yugoslavia between 1990 and 1992, the latter country having split into five successor states by 1992: Bosnia and Herzegovina, Croatia, Macedonia, Slovenia, and the Federal Republic of Yugoslavia. Serbia was then further split with the breakaway of the partially recognized state of Kosovo. Czechoslovakia too was dissolved three years after the end of communist rule, splitting peacefully into the Czech Republic and Slovakia in 1992
