The Minneapolis-founded American Indian Movement responded to the needs of urban American Indians

The American Indian Movement (AIM), founded by grassroots activists in Minneapolis in 1968, first sought to improve conditions for recently urbanized Native Americans. It grew into an international movement whose goals included the full restoration of tribal sovereignty and treaty rights. Through a long campaign of "confrontation politics," AIM is often credited with restoring hope to Native peoples.

AIM's rise occurred during a time of extreme hardship for Native Americans in the Twin Cities. A decade earlier, the federal government had passed the Indian Relocation Act, which promised good jobs and housing for Natives who moved from reservations into cities. Many of the thousands who migrated, however, found only low-wage labor, substandard housing, discrimination, violence, and despair. Their spiritual ceremonies, outlawed since 1884, were still illegal.
