African-American civil rights movement of 1950-60s - drew attention to segregation, providing social proof of the problem -> remained consistent with their views, (marches over years). Activism meant people began to think deeply about the injustice. People risked their lives several times, creating a strong belief and augmenting their message. Activists gained attention of the gov., and more people backed their position. Social change came about, but some have mo memory of events that lead to it.
