Also worth recalling is Robert Robinson's formulation: ‘The central mechanisms of imperialism may be found in systems of collaboration set up in preindustrial societies which succeeded, or failed, in meshing the incoming processes of European expansion into indigenous social politics.’ (Robinson, R. E., ‘Non-European Foundations of European Imperialism’ in: Owen, R., Sutcliffe, B. eds, Studies in the Theory of Imperialism (London 1972) 120)Google Scholar. This formula could well be transferred to contexts of indigenous Asian, African or American imperialisms, where no European participation was involved.
