A more thorough explanation:

Communism is a political and social doctrine that aims to abolish capitalism and establish a society where everyone contributes according to their ability and receives according to their needs. It is based on the ideas of Karl Marx and Friedrich Engels.

Under communism, there is no private ownership of property or means of production. Instead, everything is owned collectively by the people. The government controls the economy and distributes resources and goods equally among the population.

However, communism has often been associated with totalitarianism, where the government has complete control over all aspects of people's lives. This has led to human rights abuses and lack of individual freedoms.

Examples of communist countries include the former Soviet Union, China, Cuba, and North Korea. In these countries, the government controls all aspects of the economy and society, and individual freedoms are severely restricted.

Overall, communism is a political and social doctrine that seeks to create a classless society where everyone is equal and resources are distributed fairly. However, its implementation has often led to totalitarianism and human rights abuses.
