the theory that people join social movements because they feel deprived relative to other people or groups with whom they identify.
reactionary movement
social movement
revolutionary movement
relative deprivation theory
resource mobilization theory

Explanation:

The definition mentions people joining social movements due to feeling deprived relative to others. This directly aligns with the concept of relative deprivation theory. Reactionary, social, and revolutionary movements are types of movements, not theories explaining why people join. Resource mobilization theory focuses on resources available for a movement, not relative deprivation.
