I’m 1969, protestors for american indian right occupied

The Occupation of Alcatraz was an occupation of Alcatraz Island by 89 American Indians and supporters, led by Richard Oakes, LaNada Means, and others. They chose the name Indians of All Tribes (IOAT)[1] and John Trudell was the spokesperson. According to the IOAT, under the Treaty of Fort Laramie (1868) between the U.S. and the Lakota, all retired, abandoned or out-of-use federal land was returned to the Native people who once occupied it. Since Alcatraz penitentiary had been closed on March 21, 1963, and the island had been declared surplus federal property in 1964, a number of Red Power activists felt the island qualified for a reclamation.

The Alcatraz Occupation lasted for nineteen months, from November 20, 1969, to June 11, 1971, and was forcibly ended by the U.S. government. The Occupation of Alcatraz had a brief but somewhat direct effect on federal Indian Termination policies, and established a precedent for Indian activism. Oakes was shot to death in 1972, and the American Indian Movement was later targeted by the federal government and the FBI in COINTELPRO operations.

the answer would be logic.
