Idaho in the Civil War
Present-day Idaho was part of the Washington Territory from the start of the Civil War until March 3, 1863, when the Idaho Territory was formed. During this time, the soldiers who served in Idaho protected traffic on the Oregon Trail, gold fields, and the telegraph lines. The Union Army built a few forts to help handle these concerns, including Fort Boise (now Parma, Idaho) built July 4, 1863 and Fort Hall in 1863 and again in 1864. After the Civil War, many Union and Confederate veterans migrated to Idaho.
