The Militarized Interstate Dispute (MID) (v3.10) data, compiled by the Correlates of War Project, provides information about conflicts in which one or more states threaten, display, or use force against one or more other states between 1816 and 2001. Five datasets are included with this collection. The first dataset comprises essential attributes of each militarized interstate dispute from January 1, 1816, through December 31, 2001, while the second dataset includes participants in each of these disputes. The third dataset comprises essential elements of each militarized interstate incident from January 1, 1993, through December 31, 2001, including incidents that belong to disputes that began in 1992 and continued into 1993, while the fourth dataset includes participants in each of these incidents. The fifth dataset contains dyadic militarized interstate disputes, of which each dyadic MID has exactly two states involved, on opposite sides of the MID. Generated from the incident-level data, these data are from the years 1993 through 2001, and additionally are provided for MIDs that were ongoing as of December 31, 1992.
