The causes of armed conflict is most common focus among conflict researchers, and the Armed Conflict Dataset has repeatedly been used to analyze this problem. Previous versions have not contained an authoritative definition of what an onset is, and this has caused unnecessary confusion. With this release, we also provide users with a clear and user-friendly operational definition of conflict onset.This Dataset contains dates of all relevant events, and the Annual Onset and Calender Time Onset are built on the information provided here.
