Trotsky's Stalin is unique in Marxist literature in that it attempts to explain some of the most decisive events of the 20th century, not just in terms of epoch-making economic and social transformations, but in the individual psychology of one of the protagonists in a great historical drama. It is a fascinating study of the way in which the peculiar character of an individual, his personal traits and psychology, interacts with great events.

How did it come about that Stalin, who began his political life as a revolutionary and a Bolshevik, ended as a tyrant and a monster? Was this something pre-ordained by genetic factors or childhood upbringing? Drawing on a mass of carefully assembled material from his personal archives and many other sources, Trotsky provides the answer to these questions.

In the present edition we have brought together all the material that was available from the Trotsky archives in English and supplemented it with additional material translated from Russian. It is the most complete version of the book that has ever been published. On the eve of the centenary of the October Revolution, we believe that Trotsky's Stalin is relevant and inspiring as never before.
