The author places MAS in its international national, and historical contexts in order to determine the extent to which it is a unique communist party, as it claims to be. He traces the theory of "national democratic revolution, " which MAS rejects, back to Lenin, and discusses the Latin American left's reevaluation of that thesis. Ellner examines the guerrilla movement in Venezuela, the student movement of the late 1960s, and the emergence of the "New Left" in other countries, especially noting their influence on the formation of MAS. He also discusses the group's role in Venezuelan elections and it's relations with the other parties.
