Communism was a form of government in which individuals were not allowed to express religious freedom, own land or speak freely. This worried non-communist countries because they were afraid to lose these basic freedoms.
Karl Marx founded communism in the 1840s when he and Friedrich Engels realized they had the same political goals. Although their intentions at the time seemed noble, they wanted to end the exploitations of workers, they developed a system to strip people of their basic rights. The two spoke of communism as if it was a good thing, and it didn't take long for people in Asia, Europe and other countries to back the leaders. Communism still flourishes in parts of the world today.
