In this book, Pierre Frank explains how the Fourth International, founded in 1938 by Revolutionary Marxist militants, nuclei, currents and organizations, answered the problem of the construction of anti-capitalist, revolutionary political formations. As Ernest Mandel's biographical essay explains, Frank was secretary to Leon Trotsky in 1932-1933. This book draws on Frank's experience as a central leader of the Fourth International through to 1979.
Daniel Bensaïd's appendix explains the following 30 years of the Fourth International life. Two contributions develop its perspective of establishing a new independent political representation of the working class that takes into account the diversity of the working class in defending a resolutely class-based programme: a statement by founders of the French LCR explaining its decision to dissolve into the NPA; and the key resolution adopted by the Fourth International's 2009 world congress.
