In the United States, abolitionism, the movement that sought to end slavery in the country, was active from the late colonial era until the American Civil War, the end of which brought about the abolition of American slavery for non-criminals through the Thirteenth Amendment to the United States Constitution (ratified 1865).
The anti-slavery movement originated during the Age of Enlightenment, focused on ending the trans-Atlantic slave trade. In Colonial America, a few German Quakers issued the 1688 Germantown Quaker Petition Against Slavery, which marks the beginning of the American abolitionist movement. Before the Revolutionary War, evangelical colonists were the primary advocates for the opposition to slavery and the slave trade, doing so on humanitarian grounds. James Oglethorpe, the founder of the colony of Georgia, originally tried to prohibit slavery upon its founding in 1735 under the Georgia Experiment, a decision that was eventually reversed in 1750.
During the Revolutionary era, all states abolished the international slave trade, but South Carolina reversed its decision. Between the Revolutionary War and 1804, laws, constitutions, or court decisions in each of the Northern states provided for the gradual or immediate abolition of slavery. No Southern state adopted similar policies. In 1807, Congress made the importation of slaves a crime, effective January 1, 1808, which was as soon as Article I, section 9 of the Constitution allowed. Immediate emancipation became a war goal for the Union in 1862 and was fully achieved in 1865.
History
Abolitionism in Colonial America
American abolitionism began well before the United States was founded as a nation. In 1652, Rhode Island made it illegal for any person, black or white, to be "bound" longer than ten years. The law, however, was widely ignored, and Rhode Island became involved in the slave trade in 1700.
The first statement against slavery in Colonial America was written in 1688 by the Religious Society of Friends. On 18 February 1688, Francis Daniel Pastorius of Germantown, Pennsylvania, drafted the 1688 Germantown Quaker Petition Against Slavery, a two-page condemnation of slavery, and sent it to the governing bodies of their Quaker church. The intention of the document was to stop slavery within the Quaker community, where 70% of Quakers owned slaves between 1681 and 1705. It acknowledged the universal rights of all people. While the Quaker establishment did not take action at that time, the unusually early, clear, and forceful argument in the 1688 Germantown Quaker Petition Against Slavery initiated the spirit that finally led to the end of slavery in the Society of Friends (1776) and in the Commonwealth of Pennsylvania (1780). The Quaker Quarterly Meeting of Chester, Pennsylvania, made its first protest in 1711. Within a few decades the entire slave trade was under attack, being opposed by such Quaker leaders as William Burling, Benjamin Lay, Ralph Sandiford, William Southby, John Woolman, and Anthony Benezet. Benezet was particularly influential, inspiring a later generation of notable anti-slavery activists, including Granville Sharp, John Wesley, Thomas Clarkson, Olaudah Equiano, Benjamin Franklin, Benjamin Rush, Absalom Jones, and Bishop Richard Allen, among others.
Samuel Sewall, a prominent Bostonian and one of the judges at the Salem Witch Trials, wrote The Selling of Joseph (1700) in protest of the widening practice of outright slavery as opposed to indentured servitude in the colonies. This is the earliest-recorded anti-slavery tract published in the future United States.
Slavery was banned in the colony of Georgia soon after its founding in 1733. The colony's founder, James Edward Oglethorpe, fended off repeated attempts by South Carolina merchants and land speculators to introduce slavery into the colony. In 1739, he wrote to the Georgia Trustees urging them to hold firm:
The struggle between Georgia and South Carolina led to the first debates in Parliament over the issue of slavery, occurring between 1740 and 1742.
Rhode Island Quakers, associated with Moses Brown, were among the first in America to free slaves. Benjamin Rush was another leader, as were many Quakers. John Woolman gave up most of his business in 1756 to devote himself to campaigning against slavery along with other Quakers.
