Social movements are conscious, organized efforts by ordinary people to create social change through non-institutional means like protests. They study seek to understand human behavior, social problems, and social change. Movements occur when people feel relatively deprived compared to their expectations due to political, economic, organizational, demographic, or cultural factors. People join when they know others involved, have free time, and the issues are framed in a way that resonates with them. Movements require organizations, mobilization, and ideas to motivate people.
