Mao Zedong suffer the same conflict with Marxism as Lenin did. China at this time was far from industrialized, the ideal revolutionary society according to Marx, but had a much more rural peasant population. Like Lenin, Mao disagreed with Marx on the issue that a communist revolution could only be achieved in developed industrialized countries. Mao's variation of communism focused mainly on the gathering of rural farmers as opposed to urban industrial workers as Mao himself was originally a peasant pig farmer. Mao describes his version of communism as "Marxism adapted for Chinese circumstances."
Leninism and Maoism both utilizes the theories of Marxism, however fit such in the reality of their society.
