The American Indian Movement hoped that the Alcatraz islands would be made into a university as well as a cultural center.
EXPLANATION:
For this, the AIM occupied and protested in Alcatraz Island for 19 months.
The protestors lived on the island until the US government forcefully displaced them and reoccupied the islands.
The Alcatraz penitentiary was built on the land of the natives and once the penitentiary was closed in 1963, the Indians felt that they should now be returned their land.
