Pre-Modern Institutions and Later Support for Autocrats in Democratic Elections

A history of local inclusive institutions is correlated with higher levels of democracy today. However, it is unclear whether this reflects the effect of historical institutions on democracy or a prior common cause. Using a geographic natural experiment, this letter demonstrates that historical experience with inclusive institutions is related to less support for autocratic parties in nineteenth- and twentieth-century Germany. This suggests that electoral support for political parties that seek to subvert democracy can be influenced by pre-modern institutions even when they were destroyed prior to the introduction of democracy.
