American Civil War - Diplomacy

Diplomacy

Europe in the 1860s was more fragmented than it had been since before the American Revolution. France was in a weakened state while Britain was still shocked by their poor performance in the Crimean War. France was unable or unwilling to support either side without Britain, where popular support remained with the Union though elite opinion was more varied. They were further distracted by Germany and Italy, who were experiencing unification troubles, and by Russia, who was almost unflinching in their support for the Union.

Though the Confederacy hoped that Britain and France would join them against the Union, this was never likely, and so they instead tried to bring Britain and France in as mediators. The Union, under Lincoln and Secretary of State William H. Seward worked to block this, and threatened war if any country officially recognized the existence of the Confederate States of America. In 1861, Southerners voluntarily embargoed cotton shipments, hoping to start an economic depression in Europe that would force Britain to enter the war in order to get cotton.

Cotton diplomacy proved a failure as Europe had a surplus of cotton, while the 1860–62 crop failures in Europe made the North's grain exports of critical importance. It also helped to turn European opinion further away from the Confederacy. It was said that "King Corn was more powerful than King Cotton", as U.S. grain went from a quarter of the British import trade to almost half. When Britain did face a cotton shortage, it was temporary, being replaced by increased cultivation in Egypt and India. Meanwhile, the war created employment for arms makers, ironworkers, and British ships to transport weapons.

Charles Francis Adams proved particularly adept as minister to Britain for the U.S. and Britain was reluctant to boldly challenge the blockade. The Confederacy purchased several warships from commercial ship builders in Britain. The most famous, the CSS Alabama, did considerable damage and led to serious postwar disputes. However, public opinion against slavery created a political liability for European politicians, especially in Britain (who had herself abolished slavery in her own colonies in 1834).

War loomed in late 1861 between the U.S. and Britain over the Trent Affair, involving the U.S. Navy's boarding of a British mail steamer to seize two Confederate diplomats. However, London and Washington were able to smooth over the problem after Lincoln released the two. In 1862, the British considered mediation—though even such an offer would have risked war with the U.S. Lord Palmerston reportedly read Uncle Tom’s Cabin three times when deciding on this.

The Union victory in the Battle of Antietam caused them to delay this decision. The Emancipation Proclamation over time would reinforce the political liability of supporting the Confederacy. Despite sympathy for the Confederacy, France's own seizure of Mexico ultimately deterred them from war with the Union. Confederate offers late in the war to end slavery in return for diplomatic recognition were not seriously considered by London or Paris. After 1863, the Polish revolt against Russia further distracted the European powers, and ensured that they would continue to remain neutral.
