The Cayuse War was an armed conflict that took place in the Northwestern United States from 1847 to 1855 between the Cayuse people of the region and the United States Government and local American settlers. Caused in part by the influx of disease and settlers to the region, the immediate start of the conflict occurred in 1847 when the Whitman massacre took place at the Whitman Mission near present-day Walla Walla, Washington when thirteen people were killed in and around the mission. Over the next few years the Provisional Government of Oregon and later the United States Army battled the Native Americans east of the Cascades. This was the first of several wars between the Native Americans and American settlers in that region that would lead to the negotiations between the United States and Native Americans of the Columbia Plateau, creating a number of Indian reservations.
