An internationally distinguished team of historians of Nazism and Stalinism provide a summary of the most up-to-date research and offer new perspectives on issues linking the two most terrible dictatorships of modernity. Three selected themes are explored: the leadership cults of Hitler and Stalin; the "war machines" engaged in the deadly clash of 1941 to 1945; and the ways in which interpretations of the past have shifted in Germany and Russia since the demise of the dictatorships.
