Copperhead Poster
COPPERHEADS. Name applied to Northern Democrats opposed to the Union war policy during the CIVIL WAR. The name of the group may have come from the copper badges made from Indian head pennies some people wore to show their viewpoint. Another theory is that the group was named after the poisonous snake known for striking without warning. The name was first used in the New York Tribune on July 20,1861. Copperheads believed in a negotiated peace.

In response to their presumed threat, President Lincoln assumed extraordinary executive powers including censorship, suppression of the press, arrests, and suspension of habeas corpus. One of the strongest supporters of the Copperhead Movement was Dubuque newspaper editor Dennis MAHONY.
