Armed conflicts, 1946–2014


  • Therése Pettersson

In 2014, the Uppsala Conflict Data Program (UCDP) recorded 40 armed conflicts with a minimum of 25 battle-related deaths, up by six from 2013. This is the highest number of conflicts reported since 1999, and 11 of these conflicts were defined as wars, that is, conflicts generating 1,000 or more battle-related deaths in one calendar year. Further, an escalation of several conflicts, coupled with the extreme violence in Syria, resulted in the highest number of battle-related deaths in the post-1989 period. Yet, compared to the large-scale interstate wars of the 20th century, the number of fatalities caused by armed conflicts in 2014 was relatively low. Additionally, seven conflicts identified in 2013 were no longer active in 2014. However, four new conflicts erupted in 2014, all of them in Ukraine, and three previously registered conflicts were restarted by new actors. Furthermore, six conflicts reoccurred with previously registered actors. A positive development, however, is the increase to ten of the number of peace agreements concluded and signed in 2014, which represents a further four compared with 2013. And although this increase is part of a positive trend since 2011, it is worth noting that several peace processes remained fragile by the end of the year.
