On this page, you can explore the origins and findings of the investigation through interviews and lectures, a timeline, and read some of its major documents.

This is the preliminary report on the investigation into Security and the Fourth International. Many more pamphlets and books were published in the years to come.

The International Committee of the Fourth International published transcripts of the key briefs, depositions an court hearings in the Gelfand case in a two-volume edition. The documents are a devastating exposure of the US government’s infiltration of the Socialist Workers Party.

Based on extensive archival evidence, this book sheds new light on how the governments of the United States and the Soviet Union spied on and infiltrated the world Trotskyist movement from the 1930s through the 1980s.

In 1936, writing as an isolated political exile in Norway, Trotsky warned that the policies of the Stalinist regime, far from having assured the triumph of socialism in the USSR, were actually preparing the ground for the restoration of capitalism.

With an introduction by David North.

This volume examines the bloodiest period of the Stalinist repression of political opposition in the Soviet Union, debunking the myth that the Great Purges were merely the product of Stalin’s paranoia and had no overriding political logic.

Four articles by David North, originally published in 1982 on the fifth anniversary of the assassination of Workers League member Tom Henehan, provide a remarkably concise introduction to Trotskyism, the Marxism of today.
