Notable Tribal Members

Chief Little Crow spent much of his life in Minnesota, where he was the head of a Santee band. Little Crow, a bold and passionate orator, established himself as a spokesman for his people. After becoming chief around 1834, he sought justice for his people, but also tried to maintain relations with the whites. In 1862, he led the fight now known as the Minnesota Santee Conflict. In fact, this war was launched only in the face of starvation and only after the federal government didn't present land payments as promised. Little Crow was killed the following year. He is buried near Flandreau.

Current President: Anthony Reider
