The Copperheads[?] were a group of Northern Democrats who opposed the American Civil War, wanting an immediate peace settlement. They were also called Peace Democrats. They were against emancipation, formed groups to persuade Union soldiers to desert, and helped Confederate prisoners of war escape. The name Copperheads was given to them by Republicans, explicitly comparing them to venomous snakes that strike without warning.
