In The Missionary Roots of Liberal Democracy, Robert D. Woodberry (2012) claims that conversionary Protestantism influenced the emergence of stable democracies around the world. While his historical analysis is exhaustive, the accompanying empirical evidence suffers from severe inconsistencies. This letter replicates Woodberry's analysis using twenty-six alternative democracy measures and extends the time period over which the democracy measures are averaged. These two simple modifications lead to the breakdown of Woodberry's results. We find no significant relationship between Protestant missions and the development of democracy, which raises concerns about the robustness and broader applicability of Woodberry's findings. The letter discusses some alternative explanations for Woodberry's results, which can inform future research on this topic.
