A UN peacemaker is someone who works for the United Nations (or UN) to help stop wars and end conflicts between countries. They try to bring people together to find solutions without resorting to violence. They also visit countries to listen to people's stories and observe the situation to find out what is really going on. They might talk to governments, rebel groups, and other people affected by the conflict to discover solutions. Ultimately, the goal of a UN peacemaker is to prevent wars, bring disputes to peaceful resolutions, and help people in countries affected by wars and conflicts.
