Hin-mah-too-yah-lat-kekt (or hinmatóowyalahtq̓it in Americanist orthography; March 3, 1840 – September 21, 1904), popularly known as Chief Joseph, Young Joseph, or Joseph the Younger, was a leader of the wal-lam-wat-kain (Wallowa) band of Nez Perce, a Native American tribe of the interior Pacific Northwest region of the United States, in the latter half of the 19th century. He succeeded his father Tuekakas (Chief Joseph the Elder) in the early 1870s. Chief Joseph led his band of Nez Perce during the most tumultuous period in their history, when they were forcibly removed by the United States federal government from their ancestral lands in the Wallowa Valley of northeastern Oregon onto a significantly reduced reservation in the Idaho Territory.
