The striking affinities that have developed between radical-conservative movements in Western Europe and Russia since the end of the Cold War have been widely noted. This essay considers these affinities through the example of the Soviet historian and geographer Lev Nikolaevich Gumilev (1912–1992). It argues that Gumilev and the European New Right developed perspectives that were highly comparable, founded on similar principles, and articulated through similar images and allusions. Yet despite the powerful resonances in terms of basic concepts and theoretical orientation, there were nonetheless deep differences in terms of the conclusions regarding the practical implications for their respective societies that Gumilev and the Europeans deduced from these principles.
