Final answer:
Successful revitalization movements go through several stages: preliminary, coalescence, institutionalization, and decline.
Step-by-step explanation:
Successful revitalization movements go through several stages, as outlined by sociologists Blumer and Tilly. The first stage is the preliminary stage, where people become aware of an issue and leaders emerge. This is followed by the coalescence stage, where people join together and organize to raise awareness. The next stage is institutionalization, where the movement becomes an established organization. Finally, the movement may enter the decline stage if it successfully brings about the change it sought or if people no longer take the issue seriously.
