Catholics were much less likely to vote for the Nazis

A new paper was presented at the AEA meetings this January, “Religion, Economics, and the Rise of the Nazis,” by Philipp Tillman and Jörg Spenkuch, and the abstract for one version of the paper is this:

We investigate the role of religion in the electoral success of the Nazi Party in Weimar Germany. Among historians, it is a well known fact that Protestants were much more likely than Catholics to vote for Adolf Hitler. However, in spite of the historical importance of the Nazis’ rise to power, the question of whether this correlation reflects a causal effect of religion has so far remained unanswered. We use an instrumental variable approach by relying on geographic variation in religious beliefs dating back to a peace treaty in the sixteenth century. According to the principle “cuius regio, eius religio.” the Peace of Augsburg granted local rulers the right to determine the religion of their serfs. Using rulers’ choices in the aftermath of the peace as an instrumental variable for the religion of Germans living in the respective areas more than three hundred years later, we are able to document an economically large effect of Protestantism on Nazi vote shares— even after controlling for a wide range of region fixed effects and socioeconomic characteristics. Taken at face value, our estimates suggest that Catholics were about 50% less likely to vote for the Nazi Party than their Protestant counterparts. We are currently testing multiple hypotheses to explain this effect and are in the process of collecting additional data.

That is not a new claim but it is new to have serious econometrics to back it up and show the vote tallies were not caused by associated demographic factors.  You will find a related copy of the paper at the first link here.  Tillman’s home page is here.  Spenkuch is here.  Here is Spenkuch’s paper on immigration and crime.  Immigration is connected to higher rates of theft crime, although by small amounts, and not positively related to violent crime.

Addendum: Here is the most current version of the paper (pdf), with notable additions.
