This review provides an overview and critique of recent scholarship on German National Socialism. It focuses on four problems through which historians have recently challenged the Marxist scholarship that played a significant role in shaping debates on Nazism in the sixties and seventies : the composition of the Nazi electorate, the Nazi ‘racial state’, Nazi social policy, and the Holocaust. Although acknowledging the importance of such themes in recent work as the Nazi regime's racism, anti-Semitism, and modernity, the review maintains that the key issue in Marxist scholarship, the polarization between left and right during the interwar period in Europe, provides the essential context for understanding the Nazi regime's ideological extremes and racial practices. To make its case, it explores four examples of the left's influence, the German left's relative cohesion as political and social movements, its place in the discourse of ‘racial hygiene’, its role in debates on the ‘standard of living’, and finally, its relevance to Nazi expansionism and the ‘Final Solution’.
