What does Marxism really mean?
How did one man's ideas have such an influence on the world?
Why should we read him today?

Karl Marx remains the most influential and controversial political thinker in history. The movements associated with his name have lent hope to many victims of tyranny and aggression but have also proven disastrous in practice and resulted in the unnecessary deaths of millions. If after the collapse of the Soviet Union his reputation seemed utterly eclipsed, a new generation is reading and discovering Marx in the wake of the recurrent financial crises, growing social inequality and an increasing sense of the injustice and destructiveness of capitalism. Both his critique of capitalism and his vision of the future speak across the centuries to our times, even if the questions he poses are more difficult to answer than ever.

In this wide-ranging account, Gregory Claeys, one of Britain's leading historians of socialism, considers Marx's ideas and their development through the Russian Revolution to the present, showing why Marx and Marxism still matter today.
