Over the course of the twentieth century and into the new millennium, critical analysis of imperialism has been a feature of Marxist thought. One of the salient concerns of Marxist theorising of imperialism has been the uncovering of the connections between the capitalist accumulation process and the political and economic domination of the world by advanced capitalist countries. The conceptualising and theorising of imperialism by Marxists has evolved in response to developments in the global capitalist economy and in international politics.
