The revivalist doctrines of salvation, perfectionism, and disinterested benevolence led many evangelical reformers to believe that slavery was the most God-defying of all sins and the most terrible blight on the moral virtue of the United States. While white interest in and commitment to abolition had existed for several decades, organized antislavery advocacy had been largely restricted to models of gradual emancipation (seen in several northern states following the American Revolution) and conditional emancipation (seen in colonization efforts to remove black Americans to settlements in Africa). By the 1830s, however, a rising tide of anti-colonization sentiment among northern free blacks and middle-class evangelicals’ flourishing commitment to social reform radicalized the movement. Baptists such as William Lloyd Garrison, Congregational revivalists like Arthur and Lewis Tappan and Theodore Dwight Weld, and radical Quakers including Lucretia Mott and John Greenleaf Whittier helped push the idea of immediate emancipation onto the center stage of northern reform agendas. Inspired by a strategy known as “moral suasion,” these young abolitionists believed they could convince slaveholders to voluntarily release their slaves by appealing to the their sense of Christian conscience. The result would be national redemption and moral harmony.

William Loyd Garrison’s early life and career famously illustrated this transition toward immediatism among radical Christian reformers. As a young man immersed in the reform culture of antebellum Massachusetts, Garrison had fought slavery in the 1820s by advocating for both black colonization and gradual abolition. Fiery tracts penned by black northerners David Walker and James Forten, however, convinced Garrison that African Americans possessed a hard-won right to the fruits of American liberty. So, in 1831, he established a newspaper called The Liberator, through which he organized and spearheaded an unprecedented interracial crusade dedicated to promoting immediate emancipation and black citizenship. Then, in 1833, Garrison presided as reformers from ten states came together to create the American Antislavery Society. They rested their mission for immediate emancipation “upon the Declaration of our Independence, and upon the truths of Divine Revelation,” binding their cause to both national and Christian redemption. Abolitionists fought to save slaves and their nation’s soul.

In order to accomplish their goals, abolitionists employed every method of outreach and agitation used in the social reform projects of the benevolent empire. At home in the North, abolitionists established hundreds of antislavery societies and worked with long-standing associations of black activists to establish schools, churches, and voluntary associations. Women and men of all colors were encouraged to associate together in these spaces to combat what they termed “color phobia.” Harnessing the potential of steam-powered printing and mass communication, abolitionists also blanketed the free states with pamphlets and antislavery newspapers. They blared their arguments from lyceum podiums and broadsides. Prominent individuals such as Wendell Phillips and Angelina Grimké saturated northern media with shame-inducing exposés of northern complicity in the return of fugitive slaves, and white reformers sentimentalized slave narratives that tugged at middle-class heartstrings. Abolitionists used the United States Postal Service in 1835 to inundate southern slaveholders’ with calls to emancipate their slaves in order to save their souls, and, in 1836, they prepared thousands of petitions for Congress as part of the “Great Petition Campaign.” In the six years from 1831 to 1837, abolitionist activities reached dizzying heights.

However, such efforts encountered fierce opposition, as most Americans did not share abolitionists’ particular brand of nationalism. In fact, abolitionists remained a small, marginalized group detested by most white Americans in both the North and the South. Immediatists were attacked as the harbingers of disunion, rabble-rousers who would stir up sectional tensions and thereby imperil the American experiment of self-government. Fearful of disunion and outraged by the interracial nature of abolitionism, northern mobs smashed abolitionist printing presses and even killed a prominent antislavery newspaper editor named Elijah Lovejoy. White southerners, believing that abolitionists had incited Nat Turner’s rebellion in 1831, aggressively purged antislavery dissent from the region. On the ground, abolitionists’ personal safety was threatened by violent harassment. In the halls of congress, Whigs and Democrats joined forces in 1836 to pass an unprecedented restriction on freedom of political expression known as the “gag rule,” which prohibited all discussion of abolitionist petitions in the House of Representatives.

In the face of such substantial external opposition, the abolitionist movement began to splinter. In 1839, an ideological schism shook the foundations of organized antislavery. Moral suasionists, led most prominently by William Lloyd Garrison, felt that the United States Constitution was a fundamentally pro-slavery document, and that the present political system was irredeemable. They dedicated their efforts exclusively towards persuading the public to redeem the nation by re-establishing it on antislavery grounds. However, many abolitionists, reeling from the level of entrenched opposition met in the 1830s, began to feel that moral suasion was no longer realistic. Instead, they believed, abolition would have to be effected through existing political processes. So, in 1839, political abolitionists split from Garrison’s American Antislavery, forming the Liberty Party under the leadership of James G. Birney. This new abolitionist society was predicated on the belief that the U.S. Constitution was actually an antislavery document that could be used to abolish the stain of slavery through the national political system.

Significantly, abolitionist factions also disagreed on the issue of women’s rights. Many abolitionists who believed full-heartedly in moral suasion nonetheless felt compelled to leave the American Antislavery Association because, in part, it elevated women to leadership positions and endorsed women’s suffrage. The more conservative members saw this as evidence that, in an effort to achieve general perfectionism, the American Antislavery Society had lost sight of its most important goal. Under the leadership of Arthur Tappan, they left to form the American and Foreign Antislavery Society. Though these disputes were ultimately mere road bumps on the long path to abolition, they did become so bitter and acrimonious that former friends cut social ties and traded public insults.

Another significant shift stemmed from the disappointments of the 1830s. Abolitionists in the 1840s increasingly moved from agendas based on reform to agendas based on resistance. While moral suasionists continued to appeal to hearts and minds, and political abolitionists launched sustained campaigns to bring abolitionist agendas to the ballot box, the entrenched and violent opposition of slaveholders and the northern public to their reform efforts encouraged abolitionists to focus on other avenues of fighting the slave power. Increasingly, for example, abolitionists focused on helping and protecting runaway slaves, and on establishing international antislavery support networks to help put pressure on the United States to abolish the institution. Frederick Douglass is one prominent example of how these two trends came together. After escaping from slavery, Douglass came to the fore of the abolitionist movement as a naturally gifted orator and a powerful narrator of his experiences in slavery. His first autobiography, published in 1845, was so widely read that it was reprinted in nine editions and translated into several languages. Douglass traveled to Great Britain in 1845, and met with famous British abolitionists like Thomas Clarkson, drumming up moral and financial support from British and Irish antislavery societies. He was neither the first nor the last runaway slave to make this voyage, but his great success abroad contributed significantly to rousing morale among weary abolitionists at home.

Frederick Douglass was perhaps the most famous African American abolitionist, fighting tirelessly not only for the end of slavery but for equal rights of all American citizens.

The model of resistance to the slave power only became more pronounced after 1850, when a long-standing Fugitive Slave Act was given new teeth. Though a legal mandate to return runway slaves had existed in U.S. federal law since 1793, the Fugitive Slave Act of 1850 upped the ante by harshly penalizing officials who failed to arrest runaways and private citizens who tried to help them. This law, coupled with growing concern over the possibility of that slavery would be allowed in Kansas when it was admitted as a state, made the 1850s a highly volatile and violent period of American antislavery. Reform took a backseat as armed mobs protected runaway slaves in the north and fortified abolitionists engaged in bloody skirmishes in the west. Culminating in John Brown’s raid on Harper’s Ferry, the violence of the 1850s convinced many Americans that the issue of slavery was pushing the nation to the brink of sectional cataclysm. After two decades of immediatist agitation, the idealism of revivalist perfectionism had given way to a protracted battle for the moral soul of the country.

For all of the problems that abolitionism faced, the movement was far from a failure. The prominence of African Americans in abolitionist organizations offered a powerful, if imperfect, model of interracial coexistence. While immediatists always remained a minority, their efforts paved the way for the moderately antislavery Republican Party to gain traction in the years preceding the Civil War. It is hard to imagine that Abraham Lincoln could have become president in 1860 without the ground prepared by antislavery advocates and without the presence of radical abolitionists against whom he could be cast as a moderate alternative. ­­­­­­­­Though it ultimately took a civil war to break the bonds of slavery in the United States, the evangelical moral compass of revivalist Protestantism provided motivation for the embattled abolitionists.
