according to its proponents is based in Marxism and Leninism. The term describes the specific political ideology which Stalin implemented in the Soviet Union and in a global scale in the Comintern. There is no definite agreement between historians of about whether Stalin actually followed the principles of Marx and Lenin. It also contains aspects which according to some are deviations from Marxism such as socialism in one country. Marxism–Leninism was the ideology of the most clearly visible communist movement and is the most prominent ideology associated with communism. It refers to the socioeconomic system and political ideology implemented by Stalin in the Soviet Union and later copied by other states based on the Soviet model (central planning, collectivization of agriculture, communist party-led state, rapid industrialization, nationalization of the commanding heights of the economy and the theory of socialism in one country) whereas Stalinism refers to Stalin's style of governance (cult of personality and a totalitarian state).

First, Khrushchev denounced the cult of personality that had developed around Stalin, although Khrushchev himself had a pivotal role in fostering decades earlier. Khrushchev rejected the heretofore orthodox Marxist–Leninist tenet that class struggle continues even under socialism, but rather the state ought to rule in the name of all classes. A related principle that flowed from the former was the notion of peaceful coexistence, or that the newly emergent socialist bloc could peacefully compete with the capitalist world, solely by developing the productive forces of society. Anti-revisionism is a faction within Marxist–Leninism that rejects Khrushchev's theses. This school of thought holds that Khrushchev was unacceptably altering or revising the fundamental tenets of Marxism–Leninism, a stance from which the label anti-revisionist is derived. Maoism takes its name from Mao Zedong, the former leader of the People's Republic of China. It is the variety of anti-revisionism that took inspiration and in some cases received material support from China, especially during the Mao period. There are
