Diplomatic interventions and civil war: A new dataset^*

Recent research in the civil war literature has focused on how and when external actors intervene. However, to date, systematic data have not existed on diplomatic efforts in conflict management. This article fills this gap and introduces a dataset on 438 diplomatic interventions in 68 conflicts stretching from 1945 to 1999. The authors briefly outline previous research on third-party interventions in civil wars, describe the dataset in some detail, including some initial patterns in the data, and describe how this dataset contributes to research into conflict processes. The authors also demonstrate how diplomatic interventions can be incorporated into other research agendas by merging this dataset with Doyle & Sambanis's peacekeeping data and replicating their analysis to examine the role of external diplomacy on peacebuilding success. These data on interventions, moreover, can be merged with commonly used datasets on intrastate conflicts, which promises a wide range of application in civil war studies. Developing a greater understanding of when and how civil wars end, scholarship needs to take into account efforts to arrive at diplomatic solutions. And if, as the results demonstrate, externally driven diplomacy facilitates the termination of civil wars, then the policy implications are quite important.
