But what is relevant here is to understand why a Shaka was possible in Africa in the nineteenth century, before the coming of colonial rule. Had Shak… - Walter Rodney

Political divisions in Africa were no evidence of innate inferiority or backwardness. That was the state in which the continent then found itself—a point along a long road that others had traversed and along which Africa was moving. Commercial impact of Europe slowed down the process of political amalgamation and expansion, in contrast to the way trade with Africa strengthened Europe’s nation-states. When European capitalism took the form of imperialism and started to subjugate Africa politically, the normal political conflicts of the pre-capitalist African situation were transformed into weakness which allowed the Europeans to set up their colonial domination.

What was called was nothing but the extension overseas of European interests. The strategy behind international trade and the production that supported it was firmly in European hands, and specifically in the hands of the sea-going nations from the North Sea to the Mediterranean. They owned and directed the great majority of the world’s sea-going vessels, and they controlled the financing of the trade between four continents. Africans had little clue as to the tri-continental links between Africa, Europe, and the Americas. Europe had a monopoly of knowledge about the international exchange system seen as a whole, for was the only sector capable of viewing the system as a whole. Europeans used the superiority of their ships and cannon to gain control of all the world’s waterways, starting with the western Mediterranean and the Atlantic coast of North Africa. [...] Therefore, by control of the seas, Europe took the first steps towards transforming the several parts of Africa and Asia into economic satellites.

That is a profound revelation of the difference between capitalist and pre-capitalist societies; and when capitalism came into contact with the still largely communal African societies, it introduced money relations at the expense of kinship ties.
