the movement used radical forms of protest to remind people of the government's long history of unfair treatment of native americans.

The American Indian Movement (AIM).

Explanation:

The American Indian Movement was founded in 1968. It was led by Dennis Banks, Clyde Bellecourt, Vernon Bellecourt and Russell Means. The movement advocated the civil rights of the indigenous people, particularly the Native Americans. Protests were held in order to address grievances of poverty and brutality of the police power.

With the help of the movement, the interest of the Native Americans started to be valued. These allowed them to move to the urban society in order to look for jobs. The police activities that were against the natives were also monitored in order to ensure that the natives won't be exploited. The movement also addressed several issues regarding the treaties and also helped preserve the culture and tradition of the natives.
