The history of Washington in the American Civil War is atypical, as the territory was the most remote from the battlefields of the American Civil War. Although the Indian Wars in Washington were recent, there were no Indian hosilities within the area of modern Washington state, 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.
