The role of Washington Territory in the American Civil War is atypical, as the territory was the most remote from the main battlefields of the conflict. The territory raised a small number of volunteers for the Union Army, who did not fight against the Confederate States Army but instead maintained defensive positions against possible foreign naval or land attacks. Although the Indian Wars in Washington were recent, there were no Indian hostilities within the area of modern Washington, unlike the rest of the western states and territories, during the Civil War. At the start of the American Civil War, modern-day Washington was part of the Washington Territory. On March 3, 1863, the Idaho Territory was formed from that territory, consisting of the entirety of modern-day Idaho, Montana, and all but southwest Wyoming, leaving the modern-day Washington as Washington Territory.
