The article examines the links suggested by certain historians between the German experience of colonial rule in Africa before the First World War, with the massacre of the Herero, and the genocide carried out by the Nazis in Central and Eastern Europe between 1939 and 1945. While it concedes many of the points made by these historians in relation to the importance of the German colonial experience in forming ideas of racial hierarchy, it questions the assertion of a too-direct link with the Shoah and insists on the essential role played by First World War itself in catalyzing German attitudes towards expansion within Europe and in generating a culture of violence. It concludes by arguing that Nazi attitudes towards the peoples of Eastern Europe were conditioned essentially by defensive thinking, based on fears of encirclement, thus providing a justification for mass murder which, as a consequence, was not perceived as such by many ordinary Germans.
