In 1853, two years after the establishment of the Washington Territory, the first governor, Isaac Stevens, made an initial effort to make a treaty with Chief Garry and the Spokanes at Antoine Plantes' Ferry, not far from Millwood. After the last campaign of the Yakima Indian War, the Coeur d'Alene War of 1858 was brought to a close by the actions of Col. George Wright, who won decisive victories against a confederation of tribes in engagements at the battles of Four Lakes and Spokane Plains. The cessation of hostilities opened the inter-mountain valley of the Pacific Northwest to safe habitation by settlers.
