This paper addresses the silence about the Haitian revolution in the oeuvre of Karl Marx. He, who regarded revolutions as “locomotives of world history,” ignored the history of the revolution in Haiti and remained silent about its protagonists. In a brief approach to this paradox, I argue that the main reason for this blank space was Marx’s deficient analysis of contemporary racism. This is made clear in relation to 1) his acceptance of the biological meaning of race, 2) his involvement (...) in two main racisms of the time, antisemitism and colonial racism, and 3) his differentiation and gradation of historical subjects. The consequences were dramatic not because of Marx’s involvement in the racist zeitgeist but insofar as his learning process with regard to the relevance of anti-colonial movements and his awareness of negative societalization as well as its significance were not reflected in a theory of racism. This was to prove a debacle for subsequent attempts at a Marxist analysis of racism and has had effects that are still evident today. (shrink)
