The Universal Periodic Review (UPR) is a United Nations human rights mechanism that monitors, analyses, and highlights human rights violations. In this mechanism, Member States undergo a review of their human rights record conducted by other States and civil society in four-to-five-year cycles. Each UPR review cycle results in the States under review receiving and accepting recommendations addressing human rights concerns highlighted during the process. States are then tasked with adopting these recommendations through national policies and agendas before they are reviewed again in their next UPR review.
