This data collection comprises one of four companion datasets produced by the Correlates of War Project at the University of Michigan. It consists of information on annual symmetric matrices of international alliance bonds for 157 nations in the period 1815-1965. For each alliance bond, data are coded for the type of alliance, such as defense, neutrality, or entente, according to explicit national commitments.
