In the year of the 150th anniversary of the Emancipation Proclamation, Copperhead presents us with a false depiction of the Copperheads as principled men of peace instead of what they were -- often violent and always racist defenders of slavery, secession, and the Confederacy. Copperhead is propaganda for an old variation of the neo-Confederate Lost Cause myth, that the root of the Civil War was not slavery and the slave power, but an aggressive, power-mad North seeking to tyrannize, by unconstitutional means, a benign and chivalrous South. The Lost Cause myth was at its heart not a matter of a differing interpretation, but of the falsification and suppression of history in order to vindicate the Confederacy and later to justify Jim Crow.
