The Department of Peacekeeping Operations (DPKO) is dedicated to assisting the Member States and the Secretary-General in their efforts to maintain international peace and security.

DPKO provides political and executive direction to UN Peacekeeping operations around the world and maintains contact with the Security Council, troop and financial contributors, and parties to the conflict in the implementation of Security Council mandates.

Peacekeeping is political and its ultimate success depends on active and sustainable political processes or the real prospect of a peace process. The Department works to integrate the efforts of UN, governmental and non-governmental entities in the context of peacekeeping operations. DPKO also provides guidance and support on militarypolicemine action and other relevant issues to other UN political and peacebuilding missions.

DPKO traces its roots to 1948 with the creation of the first UN peacekeeping operations: UN Truce Supervision Organization (UNTSO) and UN Military Observer Group in India and Pakistan (UNMOGIP). Up to the late 1980s, peacekeeping operations were operated through the UN Office of Special Political Affairs. The official DPKO was formally created in 1992 when Boutros Boutros-Ghali took office as Secretary-General of the United Nations.

Policy, Evaluation and Training Division

The Policy, Evaluation and Training Division (DPET) is mandated to develop and disseminate the policy and doctrine guiding the work of Peacekeeping. In addition, the division has the responsibility to evaluate, at the request of the heads of the departments, how those policies are being applied, gather lessons learned and best practices, and use that information to guide the development, coordination and delivery of standarized training, so as to complete the learning cycle. DPET is also responsible for developing and maintaining strategic cooperation with various UN and external partners.
