People work to help find peace. 
Some people wear blue hats. They are called Blue Berets. They help after a war ends.
These workers watch for peace. They help people follow new rules. They also help build things. This makes lands better.
Some workers do not use weapons. They watch and tell what they see. This helps stop more fighting.
They also protect old and special things. This helps people feel at home. Peacekeeping helps the world stay calm.
Peacekeeping helps create conditions for lasting peace.
There are different ways to keep peace. Some missions are for watching. These observers are often unarmed. They watch for fighting and report what they see. Other missions act as a buffer. They stand between two sides to keep them apart. Some missions are multidimensional. These teams do many jobs, like helping a country's economy grow.
Some missions are called peace enforcement. These do not need permission from the fighting sides. These teams may use force to keep peace. 
The United Nations started this work in 1948. They sent observers to the Middle East. This was called UNTSO. It is still working today. Other groups like NATO or the African Union also do peacekeeping work.
Peacekeeping is a way to help create lasting peace in parts of the world. 
There are several ways these missions work. Some are called observation missions, which use small groups of people to watch cease-fires. These observers are usually unarmed and only report what they see. Other missions act as a buffer between two fighting sides. These larger groups of troops stand in the middle to keep the sides apart. Some missions are multidimensional, meaning they do many different jobs at once. They might help run elections or help a country's economy grow. 
Some missions are more intense and are called peace enforcement. These are often called Chapter VII missions. Unlike other types, they do not always need the permission of the fighting sides to operate. These teams are usually larger and carry more equipment. They may use force to make sure a peace agreement is followed. This is different from Chapter VI missions, which require the consent of all sides. If those sides stop giving consent, Chapter VI peacekeepers must leave. 
Peacekeeping has a long history that began with the United Nations. The UN started its first mission in 1948 in the Middle East. This mission was called UNTSO and used unarmed observers to watch an agreement. UNTSO is still working today, many years later. In 1992, a leader named Boutros Boutros-Ghali wrote a report called An Agenda for Peace. He wanted the UN to do even more to help rebuild countries after a war. This helped change how peacekeeping works in the modern world.
Peacekeeping is not only done by the United Nations. Other groups like NATO and the African Union also send people to help. For example, the Multinational Force and Observers works in the Sinai Peninsula.
Peacekeeping is a set of activities designed to create conditions for lasting peace. These operations aim to reduce civilian and battlefield deaths. They also work to lower the risk of renewed warfare in areas recovering from conflict.
Peacekeeping missions are categorized by how they are authorized under international law. These authorizations are often linked to specific chapters of the UN Charter. Chapter VI missions are consent-based, meaning they require the permission of the fighting parties. If these parties withdraw their consent, the peacekeepers must also withdraw. In contrast, Chapter VII missions do not require consent to operate. If consent is lost during a Chapter VII mission, the peacekeepers are not required to leave. Under international law, peacekeepers are considered non-combatants. They must remain neutral in conflicts between belligerent parties and are protected from attacks.
There are four distinct types of peacekeeping operations. The first type is observation missions. These use small groups of military or civilian observers to monitor cease-fires or troop withdrawals. They are typically unarmed and only report what they see. They do not have the mandate to intervene if an agreement is broken. Examples include UNAVEM II in Angola in 1991 and MINURSO in the Western Sahara. The second type is interpositional missions, often called traditional peacekeeping. These involve larger, lightly armed troops that act as a buffer between fighting sides. They monitor compliance with ceasefire parameters, such as UNGUA in Guatemala in 1996.
The third type is multidimensional missions. These are more complex and involve both military and police personnel. They go beyond observing to help implement comprehensive settlements. These teams might supervise elections, reform security forces, or build new institutions. Examples include UNTAG in Namibia and ONUMOZ in Mozambique. The fourth type is peace enforcement. These are Chapter VII missions that do not require the consent of the belligerents. They use substantial military forces that are well-equipped. Unlike other missions, these forces are mandated to use force for reasons beyond self-defense. Examples include NATO operations in Bosnia and UNAMSIL in Sierra Leone.
The history of peacekeeping has shifted significantly over the decades. During the Cold War, peacekeeping was mostly interpositional and traditional. UN peacekeepers acted as buffers between states after conflicts. Many of these observers were unarmed, such as UNTSO in the Middle East. In 1992, following the Cold War, Secretary-General Boutros Boutros-Ghali published a report called "An Agenda for Peace." This report proposed a more nuanced, multi-faceted approach to international politics. It introduced concepts like preventative diplomacy, peace-making, and post-conflict reconstruction. This helped move the UN toward the multidimensional missions used today.
Modern peacekeeping involves many broader aims to ensure stability. Peace-making uses mediation and negotiation to help parties reach a settlement. Peace-keeping involves deploying lightly armed forces to build confidence and monitor agreements. Post-conflict reconstruction focuses on developing economic and social cooperation. This helps mend relations and builds infrastructure to prevent future violence. 
While the United Nations is a major player, it is not the only organization involved. Other groups implement peacekeeping missions under different mandates. The North Atlantic Treaty Organization (NATO) conducted missions in Kosovo with UN authorization. The African Union (AU) works to build an African Peace and Security Architecture. This includes the African Standby Force, which was planned for 2015. The Multinational Force and Observers (MFO) monitors the Sinai Peninsula following an agreement between Israel and Egypt in 1981.
