Rise of the Abolition Movement

From the 1830s to the 1860s, a movement to abolish slavery in America gained strength in the northern United States, led by free blacks such as Frederick Douglass and white supporters such as William Lloyd Garrison, founder of the radical newspaper The Liberator, and Harriet Beecher Stowe, who published the bestselling antislavery novel “Uncle Tom’s Cabin” (1852). While many abolitionists based their activism on the belief that slaveholding was a sin, others were more inclined to the non-religious “free-labor” argument, which held that slaveholding was regressive, inefficient and made little economic sense.

Free blacks and other antislavery northerners had begun helping fugitive slaves escape from southern plantations to the North via a loose network of safe houses as early as the 1780s. This practice, known as the Underground Railroad, gained real momentum in the 1830s and although estimates vary widely, it may have helped anywhere from 40,000 to 100,000 slaves reach freedom. The success of the Underground Railroad helped spread abolitionist feelings in the North; it also undoubtedly increased sectional tensions, convincing pro-slavery southerners of their northern countrymen’s determination to defeat the institution that sustained them.
