Chapter 18: Drifting Toward Disunion – The Nation Divides

Escalating moral and political polarization over the institution of slavery was intensified by powerful literary forces, including Harriet Beecher Stowe’s profoundly influential novel, Uncle Tom’s Cabin, which vividly exposed slavery's cruelties, and Hinton R. Helper’s The Impending Crisis of the South, which used economic data to argue that slavery harmed nonslaveholding whites. The doctrine of popular sovereignty tragically failed in the Kansas Territory, where clashes between proslavery "border ruffians" and free-soilers led to the outbreak of "Bleeding Kansas" civil war, further inflamed by John Brown’s brutal Pottawatomie Massacre and the fraudulent Lecompton Constitution. Congressional civility also collapsed when Congressman Preston S. Brooks violently assaulted Senator Charles Sumner on the Senate floor in 1856, demonstrating the extreme emotional intensity of sectional passions. The crisis deepened with the Supreme Court's incendiary 1857 Dred Scott v. Sandford decision, which legally protected slavery in all territories and enraged Republicans by declaring the Missouri Compromise unconstitutional. While the North suffered from the economic Panic of 1857, which boosted Republican demands for protective tariffs and free western homesteads, the famous 1858 Lincoln-Douglas Debates saw Stephen A. Douglas propose the Freeport Doctrine, stating that popular lack of support for protective legislation could overcome the Dred Scott ruling, a stance that irrevocably split the Democratic party. John Brown's final act, the 1859 raid on Harpers Ferry aimed at inciting a massive slave rebellion, failed but led to his execution and transformation into a martyr in the North, confirming Southern fears of abolitionist aggression. The final breaking point came in the 1860 presidential election, where Abraham Lincoln, running on a sectional Republican platform opposing the expansion of slavery, won due to the complete collapse of the national Democratic party. In rapid response, South Carolina led the secession movement, quickly followed by six other deep Southern states to form the Confederate States of America, as a final attempt at compromise, the Crittenden Amendments, was rejected by Lincoln, ensuring the impending conflict.
