I am often asked by friends and comrades to explain what exactly Marxism-Leninism-Maoism is, or how it developed, when each “ism” was produced etc. Instead of repeating myself by answering the questions I get about this on Reddit, Facebook, and in person, I decided to upload the beginner’s guide that I wrote a while back that traces the development of Marxism through the qualitative leaps of theory/practice provided by Leninism and Maoism. It was written specifically to be used as a tool for advancing the collective political development of the members of Progressive Youth Organization through group study. Hopefully, this document will serve as a compact and easy to understand guide that answers some of those frequently asked questions. I have also included the set of study questions that we used, which go along with the guide, that can be used to stimulate group discussion.
