The document discusses several key aspects of social movements:
1. Social movements are collective efforts by ordinary people to enact social change through extra-institutional means like protests and boycotts.
2. They require sustained organization, mobilization of members, and shared goals/identity in order to differentiate them from more ephemeral collective behaviors.
3. Leading theories on social movements emphasize factors like resources, political opportunities, and culture/framing that allow for grievances to be organized into sustained collective action campaigns.
