Written in 1938, Trotsky’s Transitional Program is an impassioned call to action in the struggle against decaying capitalism. It highlights key themes and demands which retain all their relevance in the contemporary struggle for socialism. It also provides a method which relatively small revolutionary Marxist cadre parties can use to bridge the gap between their small size and influence and the mass forces required to win power and establish a socialist society. This transitional method consists in approaching the broad masses of working people at their existing level of consciousness and organisation and drawing them through progressive struggles and political explanations toward a higher level of thought and action. This new edition contains an extensive introduction, notes and an appendix.
