The Cold War ended in the late 20th century as reform in the Soviet Union under Gorbachev and the collapse of Communist regimes in Eastern Europe weakened the Eastern Bloc. Gorbachev's policies of perestroika and glasnost failed to solve economic problems and led to increased dissent. Popular protests emerged demanding democratic change. The USSR dissolved in 1991 and split into independent states, bringing an end to the Cold War. However, Communist rule remained in China and a few other nations, although they adopted some capitalist economic reforms.
