What is the main objective of the American Indian movements occupation of Alcatraz island and wounded knee?

The main objective of the American Indian movements' occupation of Alcatraz Island in 1969 and the Wounded Knee incident in 1973 was to protest against the U.S. government's treatment of Native Americans and to assert their rights. These actions aimed to highlight issues such as broken treaties, poverty, and lack of sovereignty. The occupations sought to reclaim land and promote Native American identity, culture, and self-determination. Ultimately, they galvanized public awareness and support for Indigenous rights movements across the country.
