This study of the structure of the international system and its consequences for national war behavior is composed of three distinct types of data: Member Characteristic Data, Subsystem Data, and War Data, consisting of Richardson's Deadly Quarrel Data, Wright's War Data, Singer and Small's War Data, and Sorokins' Disturbance Data. In the Member Characteristic Data, each member of each subsystem is the unit of observation and the national characteristics of each member are reported. In the Subsystem Data, 21 subsystems constitute the unit of observation, with variables recording the number of members, wars, alliances, and polarity of each subsystem. The War Data report the war behavior of each of the 21 subsystems, with one record for each war as reported in the four major studies of war from which they were compiled.
