TheUnited Nations has authorized 71peacekeeping operations as of April 2018. These do not include interventions authorized by the UN like theKorean War and theGulf War.^[1] The 1990s saw the most UN peacekeeping operations to date. Peacekeeping operations are overseen by theDepartment of Peacekeeping Operations (DPKO) and share some common characteristics, namely the inclusion of a military or police component, often with an authorization for use of force underChapter VII of theCharter of the United Nations.^[2] Peacekeeping operations are distinct from special political missions (SPMs), which are overseen by theDepartment of Political Affairs (DPA). SPMs are not included in the table below.^[3][4][5]
