Peace movement is when people work together to stop violent conflicts around the world. People who are involved in the peace movement want to make sure that different countries or groups don't fight each other and can figure out how to agree and be friendly. They might use things like marches, protests, rallies, and other creative ideas to show people that peace is important. They also work with governments to help people understand why they should work together peacefully and how they can solve disagreements without fighting each other.
