Case study evidence suggests that inequality between regions in federations affects the risk of secessionist conflict. However, the conventional quantitative literature on civil war has found little support for a link between economic inequality and civil war. We argue that this seeming...

Whether qualitative or quantitative, contemporary civil-war studies have a tendency to over-aggregate empirical evidence. In order to open the black box of the state, it is necessary to pinpoint the location of key conflict parties. As a contribution to this task, this article describes a data...

The hypothesis that democratization triggers political violence has been proposed repeatedly in the quantitative literature, but it remains controversial with respect to both interstate and civil wars. Current empirical research continues to be afflicted by methodological and data problems...

Established in 1964, the Journal of Peace Research (JPR) celebrates 50 years. This anniversary special issue of the journal offers broad reviews of research areas that have been central both to the journal and to the field of peace and conflict research generally. An opening article co-authored...

When all else fails, aggrieved groups of society often resort to violence to redress their grievance - either by seeking to overthrow the ruling government or by attempting to secede. The strength of the rebel group relative to the state determines what direction the conflict will take. In...

Geographical factors play a critical role in determining how a civil war is fought and who will prevail. Drawing on the PRIO/Uppsala Armed Conflict dataset covering the period 1946-2000, the authors have determined the location of all battle-zones for all civil wars in this time period, thereby...

While climate change scenarios for the Sahel vary and are uncertain, the most popularized prediction says there will progressively be drier conditions with more erratic rainfall. According to some, an increase in violent conflicts over scarce resources should also be expected. This article...

Contributions to the quantitative civil war literature increasingly rely on geo-referenced data and disaggregated research designs. While this is a welcome trend, it necessitates geographic information systems (GIS) skills and imposes new challenges for data collection and analysis. So far,...
