Tuekakas, commonly known as
Old Chief Joseph or
Joseph the Elder (c. 1785-1871), was a
Native American leader of the Wallowa Band of the
Nez Perce. Old Joseph was one of the first Nez Percé converts to Christianity and a vigorous advocate of the tribe's early peace with whites. In 1855 he aided Washington's territorial governor and set up a Nez Percé reservation that expanded from Oregon into Idaho. The Nez Perce agreed to give up a section of their tribal lands in return for an assurance whites would not intrude upon the sacred
Wallowa Valley.
