Dyadic Dimensions of Armed Conflict, 1946—2007

Abstract In 2007, 34 armed conflicts were active worldwide, up by one from 2006 and by five from 2003, the year with the lowest number of active armed conflicts since the 1970s. While the number of conflicts increased, the number of wars, i.e. conflicts with over 1,000 battle-related deaths in a year, dropped by one to four. Five of the conflicts from 2006 were no longer active in 2007, but during the year, two previously recorded conflicts (in Mali and Pakistan) were restarted by new actors and two (in Angola and Peru) by previously recorded rebel groups. For the first time since 2004, two new conflicts were recorded: a conflict over governmental power in Niger and a territorial conflict in DRC. A conflict may involve one or more dyads or pairs of warring parties. In the 236 conflicts active since 1946, 487 dyads have been recorded in the new UCDP Dyadic Dataset. While most intrastate conflicts involve a single rebel group fighting the government, in 30 of the conflicts two or more dyads were active simultaneously. In 2002 and 2003, over 30% of the active conflicts involved more than one rebel group. The number of active rebel groups and changes in the set of groups are important elements of the complexity of any armed conflict, and the study of these aspects should be greatly facilitated with the new dataset. By adding the dyadic dimension to the study of conflicts, the analysis of a range of phenomena that have hardly been captured by previously available data is made possible.
