Alexander Long in the context of "Copperhead (politics)"

In the 1860s, the Copperheads, also known as Peace Democrats, were a faction of the Democratic Party in the Union who opposed the American Civil War and wanted an immediate peace settlement with the Confederates.

Republicans started labeling anti-war Democrats "Copperheads" after the eastern copperhead (Agkistrodon contortrix), a species of venomous snake. Those Democrats embraced the moniker, reinterpreting the copper "head" as the likeness of Liberty, which they cut from Liberty Head large cent coins and proudly wore as badges. By contrast, Democratic supporters of the war were called War Democrats. Notable Copperheads included two Democratic Congressmen from Ohio: Reps. Clement L. Vallandigham and Alexander Long. Republican prosecutors accused some prominent Copperheads of treason in a series of trials in 1864.
