When the Chinese communists took power in 1948, they brought with them
a new kind of Marxism that came to be called Maoism after their leader Mao Zedong.
(Encyclopedia Britannica)

Mao Zedong played a central role in leading the largest communist revolution in the world
outside the Soviet Union and in the ‘creative developments’ or ‘Sinification’ of Marxist-Leninist
orthodoxy to suit Chinese conditions. He combined the roles of Lenin and Stalin.
