However, how peacekeeping operations manage to improve trust in the national police has received limited attention. In this article, we evaluate whether and how UN missions can (re-)build trust in the national police focusing on the case of Mali. We combine data on UN local deployment and nationally representative survey rounds from the Afrobarometer. We use the wealth of information from the survey to disentangle the mechanisms linking UN peacekeeping to positive changes in trust in national police. Employing a difference-in-difference estimation, we find that respondents in locations that hosted UN police report higher trust toward the national police forces compared to respondents in the control group. We find that this may be due to UN police improving perceptions of safety, accessibility to and integrity of national police forces.This dataset underwent an independent verification process, complying with the AJPS Verification Policy updated June 2023, which replicated the tables and figures in the primary article. For the supplementary materials, verification was performed solely for the successful execution of the code. The verification process was carried out by the Cornell Center for Social Sciences at Cornell University. <br></br> The associated article has been awarded the Open Materials Badge.
