Final answer:
The term 'Grassroots Campaign' best describes a movement where local activists work independently to create change, which was pivotal in the success of significant movements like the Civil Rights Movement.
Step-by-step explanation:
The "boots-on-the-ground activism network" referred to in the question is best described as a Grassroots Campaign. This term captures the decentralized, local, and community-driven nature of the activism being described, where individuals take action in their local contexts to effect change. The grassroots campaign was characterized by local chapters organizing communities, registering voters, staging protests, and engaging in other forms of local activism to fight for justice. These local movements played a crucial role in transforming the nation and overcoming racist institutions.
Grassroots campaigns are critical in driving social movements, as they involve the autonomous participation of local activists and volunteers. History shows that such campaigns have been fundamental to the success of significant movements, like the Civil Rights Movement. Activists like Amzie Moore, Victoria Grey, and Annie Divine worked alongside figures like Medgar Evers and Fannie Lou Hamer, empowering communities through voter registration, boycotts, and protests. The collective action of local individuals often presents direct challenges to established institutions and can lead to societal transformation, both on a regional and national scale, as evidenced by historical movements in the United States.
