The Historical Materialism Book Series is a major publishing initiative of the radical left. The capitalist crisis of the twenty-first century has been met by a resurgence of interest in critical Marxist theory. At the same time, the publishing institutions committed to Marxism have contracted markedly since the high point of the 1970s. The Historical Materialism Book Series is dedicated to addressing this situation by making available important works of Marxist theory. The aim of the series is to publish important theoretical contributions as the basis for vigorous intellectual debate and exchange on the left. We are convinced that a project of this kind can make an important contribution to the revitalisation of critical politics and intellectual culture.
