Authoritarian Repression and Electoral Opposition: Mobilization under Germany’s Antisocialist Law

Abstract

We know little about repression’s effects on opposition party mobilization under electoral authoritarianism. I argue that targeted repression of opposition leaders has both direct negative effects on mobilization and indirect effects on activist and voter support. However, party organizations and ideological leadership can adapt to mitigate targeted repression’s effects. In Germany, from 1878–1890 the social democratic party was banned and its leaders were expelled from their home districts. I estimate difference-in-differences models that leverage variation in expulsion timing and frequency to estimate their effects on electoral outcomes. Expulsions caused declines in social democrats’ electoral support. However, their effects diminished with each additional expulsion and after the first election post-expulsions, as local party organizations adapted to maintain mobilization in electoral districts despite targeted repression.
