Social Movement: Description
A social movement is a type of group action focused on bringing about social change.
Social movements are a series of contentious performances, displays and campaigns, by which ordinary people make collective claims on others (C. Tilly).
Social movements typically are thought of as long-lasting events that attract many participants with common goals for changing a specific structure of society.
Social movements typically attract persons with different objectives for creating change, varying from peaceful demonstrations to violent confrontations.
Social movements typically have many sub-groups with somewhat different visions of structural change.
