Deadly Communities: Local Political Milieus and the Persecution of Jews in Occupied Poland

Why, after the outbreak of World War II in Eastern Europe, did the inhabitants of some communities erupt in violence against their Jewish neighbors? The authors hypothesize that the greater the degree of preexisting intercommunal polarization between Jews and the titular majority group, the more likely a pogrom. They test this proposition using an original data set of matched census and electoral returns from interwar Poland. Where Jews supported ethnic parties that advocated minority cultural autonomy, the local populations perceived the Jews as an obstacle to the creation of a nation-state in which minorities acknowledged the right of the titular majority to impose its culture across a country's entire territory. These communities became toxic. Where determined state elites could politically integrate minorities, pogroms were far less likely to occur. The results point to the theoretical importance of political assimilation and are also consistent with research that extols the virtues of interethnic civic engagement.
