Gerhard Hauck (1939–) wrote that Karl Marx never devoted to the topic of colonialism a ‘theoretical-systematic’ treatment, and he ‘always dealt with colonialism aphoristically and in marginal notes’. Such an assessment of Marx’s engagement with colonialism reflects more the scant interest and substantial marginalization of the topic in Western Marxism than the reality of the diverse sites of Marx’s deliberations of colonialism, and the diverse occasions when Marx had to engage with colonialism in the course of his theoretical, political, and historical writings. It is well known that Capital, volume I, ends with a chapter on ‘The modern theory of colonization’ and colonialism plays an important role in Marx’s investigation of the ‘so-called primitive accumulation’ in part VIII of the book. In his journalistic writings, in particular in the articles he wrote in the 1850s in the New-York Tribune, the question of colonialism in India and China figured prominently. In the following decade a specific manifestation of modern colonialism (Atlantic slavery) and an important instance of internal colonization in Europe (British rule in Ireland) became for Marx important terrains of political intervention. Moreover, in his late years, Marx became increasingly interested in the study of non-European societies, and particularly forms of property prevailing before the colonial encounter.
