The Nez Percé Indians, residing in the valleys of the Pacific Northwest, faced increasing tensions with white settlers beginning in the mid-19th century. Treaties in 1855, 1863, and 1868 defined their territorial boundaries, but disagreements, particularly over the Wallowa Valley, led to rising discontent among various leaders, including Chief Joseph. By 1877, hostilities erupted as Joseph resisted U.S. demands to relocate, prompting military actions against him. Despite several skirmishes, Joseph’s band evaded capture, receiving support from sympathetic settlers in the Bitter Root Valley.
