The Occupation of Alcatraz was an occupation of Alcatraz Island by 89 American Indians who called themselves Indians of All Tribes (IOAT). 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 direct effect on federal Indian policy and, with its visible results, established a precedent for Indian activism.
On March 8, 1964, a small group of Sioux demonstrated by occupying the island for four hours. The entire party consisted of about 40 people, including photographers, reporters and Elliot Leighton, the lawyer representing those claiming land stakes. According to Adam Fortunate Eagle, this demonstration was an extension of already prevalent Bay Area street theater used to raise awareness. The Sioux activists were led by Richard McKenzie, Mark Martinez, Garfield Spotted Elk, Virgil Standing-Elk, Walter Means, and Allen Cottier. Cottier acted as spokesman for the demonstration, stating that it was “peaceful and in accordance with Sioux treaty rights.” The protesters were publicly offering the federal government the same amount for the land that the government had initially offered them; at 47 cents per acre, this amounted to $9.40 for the entire rocky island, or $5.64 for the twelve usable acres. Cottier also stated that the federal government would be allowed to maintain use of the Coast Guard lighthouse located on the island. The protesters left under threat that they would be charged with felony. This incident resulted in increased media attention for indigenous peoples' protests across the Bay Area.
The United Council of the Bay Area Indian community initially considered writing a proposal and filing an application for the use of Alcatraz by Sioux people under the conditions of their treaty. Plans were drawn up for using the buildings on Alcatraz as a cultural center. Conversations about handing Alcatraz over to developers for commercial development created concern about the future availability of the island. A desire for more immediate action to claim space for the local Indian community was finally spurred by the loss of the San Francisco Indian Center to fire on October 10, 1969. Strategies for obtaining Alcatraz for use by the local Indian community shifted from formal applications to more immediate takeover.
