1991: Soviet Union Collapses – Cold War Ends
Riding the wave of unrest symbolized by the opening of the Berlin Wall, leaders of every Eastern European nation except Bulgaria were overthrown by popular uprisings by the end of 1989. The Soviet Union was in turmoil and there were several attempts to overthrow General Secretary Gorbachev.
Finally, on December 8, 1991, the Soviet Union collapsed. The president of the Russian Republic, Boris Yeltsin, formed the Commonwealth of Independent states. After 45 years, the Cold War, the longest war in US history, was over.
