The horrors of 20th century capitalism threw up numerous challenges by workers and peasants, who rose up in their millions to fight the system. Inspired by the successful 1917 Russian Revolution, they repeatedly created their own institutions of collective power and in doing so demonstrated not just how to organise their struggles in the present but also how to build a world free of capitalists, landlords and generals.

But these revolutionary movements quickly confronted counter-revolutionary forces, both in the repressive machinery of the state and in the workers' movement itself - trade union and political leaders with no interest in seeing workers take power. Defeating such forces required that at least the leading militants be organised in revolutionary parties dedicated to seeing the struggle through. The victorious Russian revolution brought hundreds of thousands of working class militants together in new Communist parties dedicated to working class emancipation, but tragically the revolution's defeat at the hands of the dictator Joseph Stalin turned these parties into vehicles for betrayal.

From Britain to China, from Hungary to Australia, this book tells the story of these inspiring working class struggles and uprisings and recounts the fights within the workers movement over strategies and tactics to take the struggles forward
