What was the duration of the Occupation of Alcatraz?

The Occupation of Alcatraz lasted for nineteen months, from November 20, 1969, to June 11, 1971. This significant event was led by a group of Native American activists, known as the Indians of All Tribes, who aimed to reclaim the island as a statement against the U.S. government's policies towards Native Americans and to raise awareness about their struggles. The duration of the occupation was marked by various phases of activism and negotiation, culminating in the eventual removal of the group by federal authorities. The nineteen-month duration is critical as it highlights the commitment and resilience of the protesters, as well as the public's growing awareness of Native American issues during this time. This period marked a pivotal moment in the Native American civil rights movement and significantly influenced later activism.
