Militant Group Alliances and Relationships (MGAR)

The MGAR dataset -- a collaborative effort with Erica Chenoweth, Michael C. Horowitz, Evan Perkoski, and Philip B.K. Potter -- offers an original coding of cooperative and conflictual relationships between militant groups. MGAR includes data on the type and content of relationships between 2,613 militant groups from 1950 to 2016. In total, the data record 7,409 dyad-years in which a relationship exists between groups, significantly expanding the total number of relationships identified in other work. MGAR also captures when each relationship began and ended, and what it entailed. We provide a categorization of the nature of the relationship between groups, ranging from allies (the strongest form of cooperation) to associates, supporters, fans (verbal but not material support), hosts (primarily states), rivals, and competitors (the strongest form of conflict). For each cooperative dyad-year we further code whether the relationship included operational (e.g., shared membership, joint operations, tactical advising), material (i.e., arms transfers), territorial (e.g., shared bases), training, or financial support (i.e., cash transfers).
