Saving succeeding generations from the scourge of war was the main motivation for creating the United Nations, whose founders lived through the devastation of two world wars. Since its creation, the UN has often been called upon to prevent disputes from escalating into war, or to help restore peace when armed conflict does break out, and to promote lasting peace in societies emerging from wars.

Security Council

Over the decades, the UN has helped to end numerous conflicts, often through actions of the Security Council — the organ with primary responsibility, under the United Nations Charter, for the maintenance of international peace and security. When a complaint concerning a threat to peace is brought before it, the Council’s first action is usually to recommend to the parties to try to reach agreement by peaceful means. In some cases, the Council itself undertakes investigation and mediation. It may appoint special representatives or request the Secretary-General to do so or to use his good offices. It may set forth principles for a peaceful settlement.

When a dispute leads to fighting, the Council’s first concern is to bring it to an end as soon as possible. On many occasions, the Council has issued ceasefire directives which have been instrumental in preventing wider hostilities. It also deploys United Nations peacekeeping operations to help reduce tensions in troubled areas, keep opposing forces apart and create conditions for sustainable peace after settlements have been reached. The Council may decide on enforcement measureseconomic sanctions (such as trade embargoes) or collective military action.

General Assembly

According to the Charter, the General Assembly can make recommendations on the general principles of cooperation for maintaining international peace and security, including disarmament, and for the peaceful settlement of any situation that might impair friendly relations among nations.  The General Assembly can also discuss any question relating to international peace and security and make recommendations, if the issue is not currently being discussed by the Security Council.

Pursuant to its “Uniting for Peace” resolution of November 1950 (resolution 377 (V), the General Assembly may also take action if the Security Council fails to act, owing to the negative vote of a Permanent Member, in a case where there appears to be a threat to or breach of the peace, or act of aggression. The Assembly can consider the matter immediately with a view to making recommendations to Members for collective measures to maintain or restore international peace and security.


The Charter empowers the Secretary-General to “bring to the attention of the Security Council any matter which in his opinion may threaten the maintenance of international peace and security”. One of the most vital roles played by the Secretary-General is the use of his “good offices” – steps taken publicly and in private that draw upon his independence, impartiality and integrity to prevent international disputes from arising, escalating or spreading.

Conflict Prevention

The main strategies for preventing disputes from escalating into conflict, and for preventing the recurrence of conflict, are preventive diplomacy and preventive disarmament. Preventive diplomacy refers to action taken to prevent disputes from arising or from escalating into conflicts, and to limit the spread of conflicts when they occur. It may take the form of mediation, conciliation or negotiation.

Preventive diplomacy

Early warning is an essential component of prevention, and the United Nations carefully monitors developments around the world to detect threats to international peace and security, thereby enabling the Security Council and the Secretary-General to carry out preventive action. Envoys and special representatives of the Secretary-General are engaged in mediation and preventive diplomacy throughout the world. In some trouble spots, the mere presence of a skilled envoy can prevent the escalation of tension. This work is often undertaken in cooperation with regional organizations.

Preventive disarmament

Complementing preventive diplomacy is preventive disarmament, which seeks to reduce the number of small arms in conflict-prone regions. In El Salvador, Liberia, Sierra Leone, Timor-Leste and elsewhere, this has entailed demobilizing combat forces, as well as collecting and destroying their weapons as part of an overall peace agreement. Destroying yesterday’s weapons prevents their being used in tomorrow’s wars.

Preventing Genocide and Responsibility to Protect

Prevention requires apportioning responsibility to and promoting collaboration between concerned States and the international community. The duty to prevent and halt genocide and mass atrocities lies first and foremost with the State, but the international community has a role that cannot be blocked by the invocation of sovereignty. Sovereignty no longer exclusively protects States from foreign interference; it is a charge of responsibility where States are accountable for the welfare of their people. This principle is enshrined in article 1 of the Genocide Convention and embodied in the principle of “sovereignty as responsibility” and in the concept of the Responsibility to Protect.

The Special Adviser on the Prevention of Genocide acts as a catalyst to raise awareness of the causes and dynamics of genocide, to alert relevant actors where there is a risk of genocide, and to advocate and mobilize for appropriate action. The Special Adviser on the Responsibility to Protect leads the conceptual, political, institutional and operational development of the Responsibility to Protect. The efforts of their Office include alerting relevant actors to the risk of genocide, war crimes, ethnic cleansing and crimes against humanity, enhancing the capacity of the United Nations to prevent these crimes, including their incitement.


United Nations peacekeeping operations are a vital instrument employed by the international community to advance peace and security.

The first UN peacekeeping mission was established in 1948, when the Security Council authorized the deployment of the United Nations Truce Supervision Organization (UNTSO) to the Middle East to monitor the Armistice Agreement between Israel and its Arab neighbours. Since then, there have been a total of 69 UN peacekeeping operations around the world.

Over the years, UN peacekeeping has evolved to meet the demands of different conflicts and a changing political landscape. Born at the time when the Cold War rivalries frequently paralyzed the Security Council, UN peacekeeping goals were primarily limited to maintaining ceasefires and stabilizing situations on the ground, so that efforts could be made at the political level to resolve the conflict by peaceful means.

UN peacemaking expanded in the 1990s, as the end of the Cold War created new opportunities to end civil wars through negotiated peace settlements. A large number of conflicts were brought to an end, either through direct UN mediation or by the efforts of others acting with UN support.

Countries assisted included El SalvadorGuatemalaNamibiaCambodiaMozambiqueTajikistanSierra Leone, and Burundi.  As the decade drew to a close, continuing crises led to new operations in the Democratic Republic of the Congo, the Central African RepublicTimor LesteSierra Leone and Kosovo.

In the new  millennium, peackeepers have been deployed to LiberiaCôte d’IvoireDarfurSouth SudanHaiti, and Mali.

The conflicts of today, while fewer in number, are deeply rooted. For example, the Democratic Republic of Congo, Darfur, and South Sudan today, are in a second or third wave of conflict. And many are complicated by regional dimensions that are key to their solution. In fact, some two-thirds of peacekeeping personnel today are deployed in the midst of ongoing conflict, where peace agreements are shaky or absent. Conflicts today are also increasingly intensive, involving determined armed groups with access to sophisticated armaments and techniques.

The nature of conflict has also changed over the years. Originally developed as a means of dealing with inter-State conflict, UN peacekeeping has been increasingly applied to intra-State conflicts and civil wars. Although the military remain the backbone of most peacekeeping operations, today’s peacekeepers undertake a wide variety of complex tasks, from helping to build sustainable institutions of governance, through human rights monitoring and security sector reform, to the disarmament, demobilization and reintegration of former combatants, and demining.


Within the United Nations, peacebuilding refers to efforts to assist countries and regions in their transitions from war to peace and to reduce a country’s risk of lapsing or relapsing into conflict by strengthening national capacities for conflict management, and laying the foundations for sustainable peace and development.

Building lasting peace in war-torn societies is among the most daunting of challenges for global peace and security. Peacebuilding requires sustained international support for national efforts across the broadest range of activities – monitoring ceasefires; demobilizing and reintegrating combatants; assisting the return of refugees and displaced persons; helping organize and monitor elections of a new government; supporting justice and security sector reform; enhancing human rights protections and fostering reconciliation after past atrocities.

Peacebuilding involves action by a wide array of organizations of the UN system, including the World Bank, regional economic commissions, NGOs and local citizens’ groups. Peacebuilding has played a prominent role in UN operations in Bosnia and HerzegovinaCambodiaEl Salvador, Guatemala, Kosovo, Liberia and Mozambique, as well as more recently in AfghanistanBurundi, Iraq, Sierra Leone and Timor-Leste. An example of inter-state peacebuilding has been the UN Mission in Ethiopia and Eritrea.

Recognizing that the United Nations needs to better anticipate and respond to the challenges of peacebuilding, the 2005 World Summit approved the creation of a new Peacebuilding Commission. In the resolutions establishing the Peacebuilding Commissionresolution 60/180 and resolution 1645 (2005), the United Nations General Assembly and the Security Council mandated it to bring together all relevant actors to advise on the proposed integrated strategies for post conflict peacebuilding and recovery; to marshal resources and help ensure predictable financing for these activities; and to develop best practices in collaboration with political, security, humanitarian and development actors.

The resolutions also identify the need for the Commission to extend the period of international attention on post-conflict countries and where necessary, highlight any gaps which threaten to undermine peacebuilding.

The General Assembly and Security Council resolutions establishing the Peacebuilding Commission also provided for the establishment of a Peacebuilding Fund and Peacebuilding Support Office.


In 2014, landmines and explosive hazards killed approximately 10 people every day — most of them children, women and the elderly — and severely maim countless more.  Scattered in some 57 countries and 4 territories, landmines and other explosive hazards are an ongoing reminder of conflicts which have been over for years or even decades.

The vision of the United Nations is a world free of the threat of landmines and explosive remnants of war, where individuals and communities live in a safe environment conducive to development and where the needs of victims are met. Twelve United Nations Departments and Offices of the Secretariat, specialized agencies, funds and programmes play a role in mine-action programs in 30 countries and three territories.

Mine action makes it possible for peacekeepers to carry out patrols, for humanitarian agencies to deliver assistance, and for ordinary citizens to live without the fear that a single misstep could cost them their lives.

Mine action entails more than removing landmines from the ground.  It includes high impact efforts aimed at protecting people from danger, helping victims become self-sufficient and active members of their communities and providing opportunities for stability and sustainable development.

A policy developed jointly by these institutions, the Mine Action and Effective Coordination: the United Nations Inter-Agency Policy guides the division of labor within the United Nations. Much of the actual work, such as demining and mine-risk education, is carried out by nongovernmental organizations. But commercial contractors and, in some situations, militaries, also provide humanitarian mine-action services. In addition, a variety of intergovernmental, international and regional organizations, as well as international financial institutions, also support mine action by funding operations or providing services to individuals and communities affected by landmines and explosive remnants of war. United Nations peacekeeping operations often play a key role in this process.

The mine-related activities of the UN system are coordinated by the UN Mine Action Service.  UNMAS ensures an effective, proactive and coordinated response to the problems of landmines and explosive remnants of war, including cluster munitions. It assesses and monitors the threat posed by mines and unexploded ordnance on an ongoing basis, and develops policies and standards.  The Service mobilizes resources, and advocates in support of the global ban on anti-personnel landmines. UNMAS sets up and manages mine-action coordination centres in countries and territories as part of peacekeeping operations and humanitarian emergencies or crises. More recently, UNMAS efforts have further strengthened the mine action response to the threat posed by improvised explosive devices, or IEDs.

The UN has been actively engaged in addressing the problems posed by landmines since the 1980s.  It acted decisively to address the use of weapons having indiscriminate effects when it sponsored the 1980 Convention on Certain Conventional Weapons..  In 1996, that Convention was strengthened to include the use of landmines in internal conflicts and to require that all mines be detectable.

Eventually, a growing public outcry, combined with the committed action of non-governmental organizations involved in the International Campaign to Ban Land Mines (ICBL), led to the adoption of a comprehensive global agreement.

The landmark 1997 UN Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-personnel Mines and on Their Destruction (Mine-Ban Convention) bans the production, use and export of these weapons and has nearly universal support.  As of November 2016, it had 162 States parties.

A United Nations International Day for Mine Awareness and Assistance in Mine Action is observed every year on 4 April.

On 14 April 2015, the UN Secretary-General Ban Ki-moon designated the renowned actor Daniel Craig as the first UN Global Advocate for the Elimination of Mines and Explosive Hazards at the UN Headquarters in New York.

Women and Children in Conflict

In contemporary conflicts, as much as 90 percent of casualties are among civilians, most of whom are women and children. Women in war-torn societies can face specific and devastating forms of sexual violence, which are sometimes deployed systematically to achieve military or political objectives. Moreover, women continue to be poorly represented in formal peace processes, although they contribute in many informal ways to conflict resolution.

However, the UN Security Council has recognized that including women and gender perspectives in decision-making can strengthen prospects for sustainable peace. This recognition was formalized in October 2000 with the unanimous adoption of resolution 1325 on women, peace and security. The landmark resolution specifically addresses the situation of women in armed conflict and calls for their participation at all levels of decision-making on conflict resolution and peacebuilding.

Since the agenda was set with the core principles of resolution 1325, three supporting resolutions have been adopted by the Security Council — 18201888 and 1889. The four resolutions focus on two key goals: strengthening women’s participation in decision-making and ending sexual violence and impunity.

Since 1999, the systematic engagement of the UN Security Council has firmly placed the situation of children affected by armed conflict as an issue affecting peace and security. The Security Council has created a strong framework and provided the Secretary-General with tools to respond to violations against children.The Special Representative of the Secretary-General for Children and Armed Conflict serves as the leading UN advocate for the protection and well-being of children affected by armed conflict.

Peaceful uses of outer space

The United Nations works to ensure that outer space is used for peaceful purposes and that the benefits from space activities are shared by all nations. This concern with the peaceful uses of outer space began soon after the launch of Sputnik— the first artificial satellite—by the Soviet Union in 1957, and has kept pace with advances in space technology. The United Nations has played an important role by developing international space law and by promoting international cooperation in space science and technology.

The Vienna-based United Nations Office for Outer Space serves as the secretariat for the Committee on the Peaceful Uses of Outer Space and its subcommittees, and assists developing countries in using space technology for development.
