Why is there so much alleged electoral fraud in new democracies? Most scholarship focuses on the proximate cause of electoral competition. This article proposes a different answer by constructing and analyzing an original dataset drawn from the German parliament’s own voluminous record of election disputes for every parliamentary election in the life of Imperial Germany (1871-1912) after its adoption of universal male suffrage in 1871. The article analyzes the election of over 5,000 parliamentary seats to identify where and why elections were disputed as a result of “election misconduct.” The empirical analysis demonstrates that electoral fraud’s incidence is significantly related to a society’s level of inequality in landholding, a major source of wealth, power, and prestige in this period. After weighing the importance of two different causal mechanisms, the article concludes that socio-economic inequality, by making new democratic institutions endogenous to preexisting social power, can be a major and underappreciated barrier to democratization even after the adoption of formally democratic rules.
