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. 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 military, police, mine 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.
