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 The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of A ...
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. Copperheadism was a highly contentious

and in some urban ethnic wards. In the State of Ohio, perhaps in contrast with Indiana and Illinois, the counties that had Peace Democrat majorities tended not to be along the Ohio River, but more in the central and northwestern portions of the state. Historians such as Wood Gray, Jennifer Weber and Kenneth M.

, and forming conspiracies. Still, other historians say that the draft was already in disrepute and that the Republicans greatly exaggerated the conspiracies for partisan reasons. Historians such as Gray and Weber argue that the Copperheads were inflexibly rooted in the past and were naive about the refusal of the Confederates to return to the Union. Convinced that the Republicans were ruining the traditional world they loved, they were obstructionist partisans. In turn, the Copperheads became a significant target of the National Union Party in the 1864 presidential election, when they were used to discredit the leading Democratic candidates. Copperhead support increased when Union armies did poorly and decreased when they won great victories. After the fall of Atlanta in September 1864, Union military success seemed assured, and Copperheadism collapsed.

Newspapers

The Copperheads had numerous important newspapers, but the editors never allied. In Chicago, Wilbur F. Storey made the ''

Copperhead resistance

The Copperheads sometimes talked of violent resistance and, in some cases, started to organize. However, they never actually made an organized attack. As war opponents, Copperheads were suspected of disloyalty, and their leaders were sometimes arrested and held for months in military prisons without trial. One famous example was General

. Formed in Ohio in the 1850s, it became politicized in 1861. It reorganized as the Order of American Knights in 1863 and again in early 1864 as the Order of the Sons of Liberty, with Vallandigham as its commander. One leader, Harrison H. Dodd, advocated the violent overthrow of the governments of Indiana, Illinois, Kentucky, Tennessee, and Missouri in 1864. Democratic Party leaders and a Federal investigation thwarted his " Northwest Conspiracy". Despite this Copperhead setback, tensions remained high. These tensions would contribute to physical altercations between Copperheads, Republicans, and Union soldiers in Illinois towns such as

This event would draw the attention of President Lincoln, and would become national news. Indiana Republicans then used the sensational revelation of an antiwar Copperhead conspiracy by elements of the Sons of Liberty to discredit Democrats in the 1864 House elections. The military trial of Lambdin P. Milligan and other Sons of Liberty revealed plans to set free the Confederate prisoners held in the state. The culprits were sentenced to hang, but the

intervened in '' Ex parte Milligan'', saying they should have received civilian trials. Most Copperheads actively participated in politics. On May 1, 1863, former Congressman Vallandigham declared that the war was being fought not to save the Union but to free the blacks and enslave Southern whites. The U.S. Army then arrested him for declaring sympathy for the enemy. He was court-martialed by the Army and sentenced to imprisonment, but Lincoln commuted the sentence to banishment behind Confederate lines. The Democrats nevertheless nominated him for governor of Ohio in 1863. He left the Confederacy and went to Canada, where he campaigned for governor but lost after an intense battle. He operated behind the scenes at the 1864 Democratic convention in Chicago. This convention adopted a largely Copperhead platform and selected Ohio Representative George Pendleton, a Peace Democrat, as the vice-presidential candidate. However, it chose a pro-war presidential candidate, General

Historiography

Two central questions have run through the historiography of the Copperheads: "How serious a threat did they pose to the Union war effort and hence to the nation's survival?" and "To what extent and with what justification did the Lincoln administration and other Republican officials violate civil liberties to contain the perceived menace?" The first book-length scholarly treatment of the Copperheads was ''The Hidden Civil War: The Story of the Copperheads'' (1942) by Wood Gray. In it, Gray decried the "defeatism" of the Copperheads and argued that they deliberately served the Confederacy's war aims. Also in 1942, George Fort Milton published ''Abraham Lincoln and the Fifth Column'', which likewise condemned the traitorous Copperheads and praised Lincoln as a model defender of democracy. Gilbert R. Tredway, a professor of history, in his 1973 study ''Democratic Opposition to the Lincoln Administration in Indiana'' found most Indiana Democrats were loyal to the Union and desired national reunification. He documented Democratic counties in Indiana having outperformed Republican counties in recruiting soldiers. Tredway found that Copperhead sentiment was uncommon among the rank-and-file Democrats in Indiana. The chief historians who look more favorably on the Copperheads are Richard O. Curry and Frank L. Klement. Klement devoted most of his career to debunking the idea that the Copperheads represented a danger to the Union. Klement and Curry have downplayed the treasonable activities of the Copperheads, arguing the Copperheads were traditionalists who fiercely resisted modernization and wanted to return to the old ways. Klement argued in the 1950s that the Copperheads' activities, especially their supposed participation in treasonous anti-Union secret societies, were mostly false inventions by Republican propaganda machines designed to discredit the Democrats at election time. Curry sees Copperheads as poor traditionalists battling against the railroads, banks, and modernization. In his standard history '' Battle Cry of Freedom'' (1988), James M. McPherson asserted Klement had taken "revision a bit too far. There was some real fire under that smokescreen of Republican propaganda". Jennifer Weber's ''Copperheads: The Rise and Fall of Lincoln's Opponents in the North'' (2006) agrees more with Gray and Milton than with Klement. She argues that first, Northern antiwar sentiment was strong, so strong that Peace Democrats came close to seizing control of their party in mid-1864. Second, she shows the peace sentiment led to deep divisions and occasional violence across the North. Third, Weber concluded that the peace movement deliberately weakened the Union military effort by undermining both enlistment and the operation of the draft. Indeed, Lincoln had to divert combat troops to retake control of New York City from the anti-draft rioters in 1863. Fourth, Weber shows how the attitudes of Union soldiers affected partisan battles back home. The soldiers' rejection of Copperheadism and overwhelming support for Lincoln's reelection in 1864 was decisive in securing the Northern victory and the preservation of the Union. The Copperheads' appeal, she argues, waxed and waned with Union failures and successes in the field.


Flags

There was no official flag for Copperheads: they differed from area to area. Most contemporary accounts indicate some flags had a white field with the inscription "peace" and "nation."Vinti Singh, Historic Brookfield flag symbolizes intricacies of Civil War political divide, ''newstimes'' April 9, 2010
/ref> Others were the standard national flag with 13 to 22 stars and 11-7 stripes known as "exclusionary flags". They mostly removed the stars of rebel states or Union states. The flags were also popular with the opposition Some retained their 34 stars but put political slogans in their stripes.
