Some reasons:
Communism had finally outlived its credibility as a political/economic system vs the capitalist one. People in eastern Europe as well as in the Soviet Union, could see for themselves by the 1980's, that their governments were incapable of enhancing the people's standard of living and preventing consumer shortages that appeared everywhere! Poland was the first to defy the Soviets and the Polish leadership. The election of Pope John Paul 2 was to prove to be the catylist along with the Solidarity Movement, to force changes. Other Soviet bloc countries could see what was happening and found encouragement. The other monumental change was the appointment of Michail Gorbechov of the Soveit Union in 1985. He knew that the status quo could no longer save not only his country but other countries under Soviet control. He opened up the press and the economy and tried his best to reform the Communist system without replacing it. The end came when he told the East German President, Erich Honneker in 1989, that the Soviets would not rescue the East German government and that they had to make sweeping reforms if they wanted to stay in power. Soon after, the Berlin Wall fell and by the end of the year, every country overthrew its communist dictatorships, except the Soviet Union and Rumania. Had these countries opened up like the Chinese did around the same time, the consequences might have been different-assuming the people would be fine with few political rights but a far better economic system. I doubt it.
The Chinese communists made the right reforms and were much more pragmatic in maintaining control over its people.
The Soviet Union Collapsed because of several reasons, in fact, to many to name them all. However the key point is that during the Cold war/arms race with the USA, The Soviet Union's economy collapsed. It's people began to question the communist Ideal, and much reform began to be suggested. Without Money, you have nothing.
The Communist regimes in Eastern Europe collapsed and the Cold War came to an end.
they bitterly resented it ☺☻
Tracey F. Judson has written: 'Civil society, second society and the breakdown of communist regimes in Central and Eastern Europe'
There are actually five communist regimes located on the continent of Asia. They are North Korea, China, Malaysia, Singapore, and East Timor.
During World War II, Eastern Europe was primarily under the control of three types of government: fascist, communist, and collaborationist regimes. Fascist governments, such as Nazi Germany and fascist Italy, occupied and controlled countries like Poland, Hungary, and Romania. Communist governments, led by the Soviet Union, emerged in Eastern European countries like Poland, Czechoslovakia, and Bulgaria. Collaborationist regimes were also established in countries like Croatia and Slovakia, which cooperated with the Axis powers.

Gorbachev's two major policies were glasnost and perestroika, which means openness and restructuring. He welcomed criticism of the government, which was never before allowed in the U.S.S.R. He wanted to reform or restructure the economy and especially the communist party within U.S.S.R. He allowed freedom of press and released political prisoners. He encouraged the rulers of the eastern European countries to adopt the same policies. The people of eastern Europe stood up against the oppressive regimes (although some eastern European rulers did follow in Gorbachev's footsteps and allowed free elections). The people initially feared that the Soviet army would suppress the uprisings like it had before, but Gorbachev did not provide help to the Communist regimes. Hence by 1991, communism was rejected by the eastern Europe.
The collapse of communism in the Soviet Union and Eastern Europe was a series of events that led to the dissolution of communist regimes in the late 1980s and early 1990s. This collapse was spurred by a combination of factors, including economic stagnation, political repression, and popular discontent. The fall of the Berlin Wall in 1989 symbolized the end of communist rule in Eastern Europe, while the dissolution of the Soviet Union in 1991 marked the final collapse of communism in the region.
The Revolutions of 1989 were the revolutions which overthrew the communist regimes in various Central and Eastern European countries.The events began in Poland in 1989, and continued in Hungary, East Germany, Bulgaria, Czechoslovakia and Romania. Romania was the only Eastern Bloc country to overthrow the regime violently. The Berlin wall also came down in Germany.
The Cold War developed from the conflict between the US and the USSR, which sought to become the dominant world power. The US opposed all communist governments, while the USSR supported many, and established puppet regimes in Eastern Europe.
Most of Eastern Europe was occupied by Soviet Russia after the Second World War. They then set up puppet governments in those countries. (You can argue about if the Soviets in the 1940's-1990's were actually Communists or not else where)
American politicians supported corrupt regimes in Latin America during the Cold War as part of their strategy to prevent the spread of communism in the region. They saw these regimes as bulwarks against leftist movements, even if they were authoritarian and engaged in corrupt practices. Additionally, there were economic interests and geopolitical considerations that influenced their support for these regimes.
