Dennis Banks was a Native American activist, teacher, and author. He was a longtime leader of the American Indian Movement, which he co-founded in Minneapolis, Minnesota in 1968 to represent urban Indians. He was a pre-eminent spokesman for Native Americans. His protests won government concessions and created national attention and sympathy for the oppression and deplorable endemic social and economic conditions for Native Americans.

The American Indian Movement (AIM) is an American Indian grassroots movement which was founded in Minneapolis, Minnesota in July 1968, initially centered in urban areas in order to address systemic issues of poverty, discrimination, and police brutality against American Indians. AIM soon widened its focus from urban issues to many Indigenous Tribal issues that American Indian groups have faced due to settler colonialism in the Americas. These issues have included treaty rights, high rates of unemployment, the lack of American Indian subjects in education, and the preservation of Indigenous cultures.
