UCDP Peace Agreement Dataset

UCDP Peace Agreement Dataset v. 2.0, 1975-2011

Content: The new Peace Agreement dataset, that covers peace agreements signed between at least two opposing primary warring parties in an armed conflict 1975-2011. The dataset is compatible with the UCDP Dyadic Dataset v. 1-2012, and UCDP/PRIO Armed Conflict Dataset v.4-2012. It has been constructed to allow researchers to analyze the different peace agreements. The unit of analysis is the peace agreement; consequently more than one agreement can be registered for one conflict- or dyad-year in the UCDP data. Each agreement is categorized as a comprehensive agreement, a partial agreement or a peace process agreement, depending on if the agreement is seen as a final product in a peace process or if the parties still have outstanding issues that have to be solved. Each agreement is also attributed with conflict, dyad and actor IDs from the other UCDP data to enhance the merging of different UCDP data collections.The UCDP Peace Agreement Dataset includes information on e.g. name, date, signatories and third parties of the agreement. Furthermore, it contains information on the provisions of the accords as well as different variables concerned with the termination of violence.
