Walter Rodney, in his 1972 classic How Europe Underdeveloped Africa, proposes the idea that imperialism is a phase of capitalism "in which Western European capitalist countries, the US, and Japan established political, economic, military and cultural hegemony over other parts of the world which were initially at a lower level and therefore could not resist domination." As a result, Imperialism "for many years embraced the whole world – one part being the exploiters and the other the exploited, one part being dominated and the other acting as overlords, one part making policy and the other being dependent."
