The purpose of this data collection was to identify and to date wars between major and minor powers. Data were collected and collated on initiation of wars, participation and termination date for each participant, outcome, and, whenever possible, total casualties suffered in the conflict. The individual battle was taken as the basic unit of analysis. If contestants were the same, but more than six months separated each individual battle, and battles met certain other criteria, each was treated as a separate war. If not, they were coded as part of one larger conflict. A total of 65 wars that involved one major and one minor power on opposing sides were identified for this collection.
