Communism
Since 1989, when the Berlin Wall was torn down, most countries that used to be communist have returned to capitalism. Communism now has much less influence around the world. In 1991, the Soviet Union broke up. However, around a fifth of the world's people still live in states controlled by a communist party. Most of these people are in China. The other countries include Cuba, Vietnam, Laos, and North Korea. There are also communist movements in Latin America and South Africa.
