A few years after the Nazis came to power in Germany, an alliance of states and nationalistic movements formed, revolving around the German axis. That alliance, the states involved, and the interplay between their territorial aims and those of Germany during the interwar period and World War II are at the core of this volume. This “territorial revisionism” came to include all manner of political and military measures that attempted to change existing borders. Taking into account not just interethnic relations but also the motivations of states and nationalizing ethnocratic ruling elites, this volume reconceptualizes the history of East Central Europe during World War II. In so doing, it presents a clearer understanding of some of the central topics in the history of the war itself and offers an alternative to standard German accounts of the period and East European national histories.
