In 1805, when visited by Lewis and Clark, they were occupying a large region in W Idaho, NE Oregon, and SE Washington. In the 1830s the Nez Percé, then numbering some 6,000, attracted national attention by sending emissaries to St. Louis to ask for books and teachers. Their request attracted to the Pacific Northwest missionaries, who played an important role in opening the region to settlement. The Nez Percé ceded (1855) a large part of their territory to the United States. The gold rushes in the 1860s and 1870s, however, brought large numbers of miners and settlers onto their lands, and a treaty of cession was fraudulently extracted (1863) from part of the tribe, confining the Nez Percé to a reservation in NW Idaho. A band of the tribe living in Oregon refused to relocate, leading to the uprising under Chief Joseph in 1877. Following their defeat, many of the survivors ended up at the Colville Reservation in Washington, where some of their descendants still live. However, many more Nez Percé live on their reservation in Idaho, earning their living as farmers. In 1990 there were some 4,000 Nez Percé in the United States.

The Nez Percé Stake Race is a type of pole bending race. It is one of five competition game events approved for specialty shows by the Appaloosa Horse Club. The race was inspired by the games played by the Nez Percé exhibiting their riding skills.
Unlike traditional pole bending races, two horses race on identical courses laid out side-by-side with the loser eliminated and the winner moving up the brackets to race the other winners.
