We study the effects of war on bilateral trade with available data extending back to 1870. Using the gravity model, we estimate the contemporaneous and lagged effects of wars on the trade of belligerent nations and neutrals, controlling for other determinants of trade as well as the possible effects of reverse causality. We find large and persistent impacts of wars on trade, on national income, and on global economic welfare. We also conduct a general equilibrium comparative statics exercise that indicates costs associated with lost trade might be at least as large as the conventionally measured "direct" costs of war, such as lost human capital, as illustrated by case studies of World War I and World War II.
