Wages of War, 1816-1965

The Wages of War is part of the Correlates of War (COW) Project at the University of Michigan under the guidance of J. David Singer and Melvin Small. The data are meant to be a statistical handbook of war from 1816-1965. It includes mainly bivariate data on every war fought in the time period. War data described cover all international wars that began and ended between 1816 and 1965, and those that satisfied the theoretical criteria: political status of the belligerents and the severity of the armed conflict in terms of battle-connected fatalities. These criteria are applied to a chronological list of all deadly quarrels between 1816 and 1965. Note: It is believed these data contain serious errors and should not be used. However, since the replacement data for International Disputes was never provided to ICPSR by the principal investigator, these files may be the only source for parts of those data.
