Revolutions of 1989
The Revolutions of 1989 or the Fall of Communism were a series of revolutions against communist and socialist governments around the world, especially in Europe. It caused the end of the Cold War, saw the end of most communist states and the United States becoming the world's only superpower. It also caused the end of the Soviet Union due to the 1991 Soviet coup d'état attempt and the fall of the Berlin Wall in 1989. After the revolutions, the only remaining communist countries were China, Cuba, Laos, North Korea and Vietnam, however people in these countries did hold protests against the government (like the 1989 Tiananmen Square protests in China) and there were many reforms after 1991 (like đổi mới in Vietnam, which was similar to Mikhail Gorbachev's reforms in the Soviet Union, glasnost and perestroika).
