Step-by-step explanation:
The civil rights movement of the 50s and 60s included a form of social movement that sociologists refer to as grassroots activism. This movement was comprised of campaigns and demonstrations led by ordinary people, rather than governmental or institutional leaders. These activist efforts were crucial in spurring the federal government to take action to protect civil rights and ensure equal economic and educational opportunities for all. Although the African American civil rights movement was the most prominent, other ethnic minorities also fought for equality, often using similar tactics. The movement aimed to end racial segregation and discrimination against African Americans and secure legal recognition and federal protection of the citizenship rights enumerated in the Constitution and federal law.
