Introducing the Civil Wars Mediation (CWM) dataset

Mediation is one of the few mechanisms the international community can deploy that will affect civil wars. This article introduces the dataset on mediation in civil wars – termed the Civil War Mediation (CWM) dataset. This is the first dataset to focus solely on civil war mediation. These data contribute to the present state of quantitative research on mediation in three important respects: the data are collected for the period of 1946–2004, are organized by mediation cases and by civil war episode, and provide detailed information about mediation incidences. The article first presents a few variables included in the dataset that are motivated by theoretical arguments from the literature. After a presentation of summary statistics, attention is turned to using the CWM data to explore the determinants of mediation. Mediation is shown to be a function of war type (territorial and internationalized wars are more likely to be mediated), war duration (the longer the war the higher the probability of mediation), supply-side factors (the number of democracies in the world and the global polity average), and stratum (subsequent wars are less likely to be mediated). Battle-related deaths also seem to increase the chances of mediation, though the relationship is only weakly significant. The article concludes with suggestions for future research that can benefit from the dataset.
