Communism, is a religion that is now failing due to its sinful nature. The followers of this cult were called Communists or Reds. The Communist Manifesto and also their beliefs contradicts the beliefs of others by inserting an atheist regime.
A man named Karl Barx invented the idea for this world to follow when they were bored. Unfortunately his beliefs were bullshit and others twisted around the manifesto and of the Communist Party of Germany and Russia.
