Chief Joseph (March 3, 1840 – September 21, 1904), succeeded his father Tuekakas (Chief Joseph the Elder) as the leader of the Wal-lam-wat-kain (Wallowa) band of Nez Perce, a Native American tribe indigenous to the Wallowa Valley in northeastern Oregon, in the interior Pacific Northwest region of theUnited States.
He led his band during the most tumultuous period in their contemporary history when they were forcibly removed from their ancestral lands in the Wallowa Valley by the United States federal government and forced to move northeast, onto the significantly reduced reservation in Lapwai, Idaho Territory. A series of events which culminated in episodes of violence led those Nez Perce who resisted removal including Joseph's band and an allied band of the Palouse tribe to take flight to attempt to reach political asylum, ultimately with the Lakota chief Sitting Bull in Canada.
Young-Man-Afraid-Of-His-Horses [Tȟašúŋke Kȟokípȟapi] (1836–1900), also translated as His-Horses-Are-Afraid and They-Fear-Even-His-Horses, was a chief of the Oglala Sioux.
Commonly misinterpreted, his name means They fear his horse or His horse is feared meaning that the bearer of the name was so feared in battle that even the sight of his horse would inspire fear. He is known for his participation in Red Cloud's War, as a negotiator for the Sioux Nation after the Wounded Knee Massacre, and for serving on delegations to Washington, D.C.
