Dangerous Outsiders to the Volksgemeinschaft ? Adjudicating Accusations against German Citizens of Polish Descent in the WWII-Era Ruhr

This article examines the negotiation of ethnopolitical categories in wartime Nazi Germany by analyzing Gestapo investigations into accusations of “friendliness to Poland” against German citizens of Polish descent in the industrial Ruhr conurbation. By relying heavily on denunciations and informing, the Gestapo incentivized ordinary Germans in the Ruhr to identify perceived “dangerous outsiders” to the Volksgemeinschaft . Some therefore relied on longstanding anti-Polish tropes to frame accusations in the racial categories of the Nazi state. But while many such accusations alerted the Gestapo’s attention, they frequently masked a pursuit of personal issues and presented officers with significant investigatory difficulties. Unlike the generally brutal treatment of ethnolinguistic minorities in Nazi Germany, Gestapo officers often did not simply employ blanket repression in these cases. They frequently considered accused individuals’ socioeconomic productivity and “commitment” to Germany, characteristics that defendants stressed, thus highlighting the often contingent, unstable process of ethnic boundary formation in Nazi Germany.
