Аннотация:Abstract. In postcommunist politics many of the ‘new national right’ political formations in Eastern Europe and the former Soviet Union have joined forces with the communist successor parties. Such a combination is, on the surface, a baffling mixture; how is it possible that two fundamentally different ideological approaches (nationalism and internationalist socialism) can coexist and actively cooperate to form such a potent political force? What are the conditions under which such political cooperation emerges? This article attempts to answer the above questions by, first, empirically testing the effects of several factors which might explain postcommunist–nationalist political cooperation. Second, the quantitative analysis is buttressed with a comparison of the Hungarian and Russian cases. The analysis indicates that the most important variable associated with the emergence of postcommunist–nationalist political cooperation is the effect of previous regime type.
