Here is a good summary:
Maoism only emerged as Maoism proper at the end of the 1980s and beginning of the 1990s when capitalism was declaring communism extinct: first with the people’s war carried out by the Communist Party of Peru (PCP), and the emergence of the Revolutionary Internationalist Movement (RIM) with its 1993 statement Long Live Marxism- Leninism-Maoism!. It was in this context that the experience of the Chinese Revolution––its successes and failures––was systematically examined and “Maoism” was declared the third stage of revolutionary science. For the first time, then, “Maoism” was theorized as an actual ideology rather than just a “thought” that had replaced Stalin’s thought as the interlocuter of Marxism-Leninism; the PCP and the RIM argued for Maoism-qua-Maoism rather than Maoism-qua-Mao Zedong Thought, claiming that what they called “Maoism” was a theoretical development of scientific communism, a continuity and rupture from Marxism-Leninism, because it possessed tenets that were universally applicable. Hence, the RIM would argue that Maoism is the latest encapsulation of Marxism and Leninism, and Marxism-Leninism as it was is no longer sufficient.
The RIM document Long Live Marxism-Leninism-Maoism! would proclaim that all communisms that argued for a communism pre-Mao, pre-Lenin, or even pre-Marx were “revisionist”, much like arguing for a theory of physics pre-Einstein was theoretically backwards.
JMP, Trotskyism or Maoism?
P.S. I was also unaware that you are a supporter of the on-going Peoples Wars. Did you join this group to ask this question or are you a genuine supporter?
P.P.S. If I didn't make it clear enough, I'd just like to emphasize that this is a question of Marxism-Leninism-Maoism, or MLM, versus Mao Zedong Thought, or MZT (which is shorthand for ML-MZT).
You mixed these up a bit
