Background
Abolitionism, used as a single word, was a movement to end slavery, whether formal or informal. The term has become adopted by those seeking the abolishment of any perceived injustice to a group of people. Abolitionists included those who joined the American Anti-Slavery Society or its auxiliary groups in the 1830s and 1840s as the movement fragmented. The fragmented anti-slavery movement included groups such as the Liberty Party; the American and Foreign Anti-Slavery Society; the American Missionary Association; and the Church Anti-Slavery Society. Historians traditionally distinguish between moderate antislavery reformers or gradualists, who concentrated on stopping the spread of slavery, and radical abolitionists, whose demands for unconditional emancipation often merged with a concern for black civil rights.

William Lloyd Garrison
Antislavery as a principle was far more than just the wish to limit the extent of slavery. Most Northerners recognized that slavery existed in the South and the Constitution did not allow the federal government to intervene there. Most Northerners favored a policy of gradual and compensated emancipation. After 1849 abolitionists rejected this and demanded it end immediately and everywhere. John Brown was the only abolitionist known to have actually planned a violent insurrection, though David Walker promoted the idea. The abolitionist movement was strengthened by the activities of free African-Americans, especially in the black church, who argued that the old Biblical justifications for slavery contradicted the New Testament.
African American Abolitionists
African-American activists and their writings were rarely heard outside the black community; however, they were tremendously influential to some sympathetic white people, most prominently the first white activist to reach prominence, William Lloyd Garrison [], who was its most effective propagandist. Garrison's efforts to recruit eloquent spokesmen led to the discovery of ex-slave Frederick Douglass [], who eventually became a prominent activist in his own right. Eventually, Douglass would publish his own, widely distributed abolitionist newspaper, the North Star.
Frederick Douglass
Frederick Douglass (1818–1895), a former slave whose memoirs, Narrative of the Life of Frederick Douglass, an American Slave (1845) and My Bondage and My Freedom (1855), became bestsellers which aided the cause of abolition.
In the early 1850s, the American abolitionist movement split into two camps over the issue of the United States Constitution. This issue arose in the late 1840s after the publication of The Unconstitutionality of Slavery by Lysander Spooner. The Garrisonians, led by Garrison and Wendell Phillips, publicly burned copies of the Constitution, called it a pact with slavery, and demanded its abolition and replacement. Another camp, led by Lysander Spooner, Gerrit Smith, and eventually Douglass, considered the Constitution to be an antislavery document. Using an argument based upon Natural Law and a form of social contract theory, they said that slavery existed outside of the Constitution's scope of legitimate authority and therefore should be abolished.
