Wilma Mankiller (1945-2010) was a Cherokee activist who was driven to political activism through becoming involved with the Occupation of Alcatraz. Focusing on the logistical side of the occupation, Mankiller was crucial in ensuring that much needed supplies made their way to the island.
After the occupation, Mankiller became involved with the Pit River Tribe's efforts to defend their ancestral lands from an encroaching Pacific Gas and Electric Company. Following the damming of the Pit River at the hands of PG&E, the Pit River Tribe reclaimed the land as theirs following the environmental toll that the dam had on the surrounding area.
