A political leader and a fierce warrior, Red Cloud, chief of the Oglala Sioux, fought unsuccessfully to save his people and their land from being seized by whites. Born in 1822 in what was then Nebraska Territory, Red Cloud was named Mahpiua-Luta at birth. He became a chief after showing leadership and bravery in battles against the Oglala's traditional enemies, the Pawnees, Crows, Utes, and Shoshones. He also divided the Oglala by killing the rival of his uncle, another tribal leader. Learn more with this biography from American Experience: "U.S. Grant - Warrior."
