Although modern racism was fully developed by their time, Marx (and Engels) did not engage in a theoretical discussion of its essential features. This analytical silence is investigated in the chapter Marx and Haiti: Notes on a Blank Space. At the same time, the chapters of this volume demonstrate that and why the principles of a historical materialist analysis of society present links for a critical theory of racism. In the chapter Dehumanization and Social Death: Fundamentals of Racism, this is shown concerning the various historical shapes of racisms caused by different forms of class relations. The chapter Racismflq: Birth of a Concept connects the conceptual history of racism with the socio-historical conflicts of differently affected social groups. Finally, the chapter A Historical Materialist Theory of Racism: Introduction addresses basic elements of a Marxist analysis of racism. It elucidates the necessity of a theoretical conjunction of classist and racist discrimination as well as the historical differentiation of racisms.
