Answers to this classic question are dominated by the lack of causality. We exploit the Vietnam Draft Lottery -- a natural experiment that drafted male U.S. citizens into military service during the Vietnam War -- to conclusively show that war increases religiosity. We measure religiosity via religious imagery on web-scraped photographs of hundreds of thousands of gravestones of deceased U.S. Americans using a tailor-made convolutional neural network. Our analysis provides compelling and robust evidence that war indeed increases religiosity: people who were randomly drafted into war are at least 20% more likely to have religious gravestones. This effect sets in almost immediately, persists even after 50 years, and generalizes across space and societal strata.
