The American Indian Movement confronted the government through protests and marches.

Explanation:

The American Indian Movement was an organization of civil rights ounded on 1968, created originally to help the displaced indigenous of the cities.  

Over time, it endeavored to expand his efforts to support demands for economic independence, autonomy over tribal areas, the restoration of illegally confiscated lands and the protection of the legal rights and traditional culture of the indigenous peoples. Some of their protest activities were involved in violence.

In 1972 the movement occupied the headquarters of the Bureau of Indian Affairs in Washington DC. But it gained national recognition since the occupation of Wounded Knee in 1973.

Internal disputes and the imprisonment of some of its leaders resulted in the dissolution of its national leadership in 1978, although the local unions have continued with their function.
