Visible protests reflect both continuity and change. This Element illustrates how protest around longstanding issues and grievances is punctuated by movement dynamics as well as broader cultural and institutional environments. The disability movement is an example of how activist networks and groups strategically adapt to opportunity and threat, linking protest waves to the development of issue politics. The Element examines sixty years of protest across numerous issue areas that matter for disability including social welfare, discrimination, transportation, healthcare, and media portrayals. Situating visible protest in this way provides a more nuanced picture of cycles of contention as they relate to political and organizational processes, strategies and tactics, and short-and-long-term outcomes. It also provides clues about why protest ebbs and flows, when and how protest matters, who it matters for, and for what.
