See also: History of United Nations peacekeeping. This is a list of United Nations peacekeeping missions since the United Nations was founded in 1945, organized by region, with the dates of deployment, the name of the related conflict, and the name of the UN operation.
Peacekeeping, as defined by the United Nations, is a way to help countries torn by conflict create conditions for sustainable peace. UN peacekeepers—soldiers and military officers, police officers and civilian personnel from many countries—monitor and observe peace processes that emerge in post-conflict situations and assist ex-combatants in implementing the peace agreements they have signed. Such assistance comes in many forms, including confidence-building measures, power-sharing arrangements, electoral support, strengthening the rule of law, and economic and social development.
The Charter of the United Nations gives the Security Council the power and responsibility to take collective action to maintain international peace and security. For this reason, the international community usually looks to the Security Council to authorize peacekeeping operations. Most of these operations are established and implemented by the United Nations itself with troops serving under UN operational command. In other cases, where direct UN involvement is not considered appropriate or feasible, the Council authorises regional organisations such as the North Atlantic Treaty Organisation, the Economic Community of West African States or coalitions of willing countries to implement certain peacekeeping or peace enforcement functions.In modern times, peacekeeping operations have evolved into many different functions, including diplomatic relations with other countries, international bodies of justice (such as the International Criminal Court), and eliminating problems such as landmines that can lead to new incidents of fighting.
