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.
