Issac Ingalls Stevens, appointed governor of the Washington Territory in 1853, was in charge of Indian relations there. Seeking a feasible railroad route through the territory, he coerced and threatened tribes west of the Cascades to cede their land. Hi s negotiations with the Nez Perce in 1855 were disrupted by intertribal fighting, and the resulting treaty was not honored by the Indians. War broke out between white settlers and Indians throughout the Northwest. Many chiefs turned against Stevens, and they managed to convince officers of the U.S. Army that the distrust he had generated among the tribes was the cause of the fighting.
