Abolitionism was a movement to end the slave trade and emancipate slaves in western Europe and the Americas. The slave system aroused little protest until the 18th century, when rationalist thinkers of the Enlightenment criticized it for violating the rights of man, and Quaker and other evangelical religious groups condemned it as un-Christian. Though antislavery sentiments were widespread by the late 18th century, they had little immediate effect on the centers of slavery: the West Indies, South America, and the Southern United States. Britain banned the importation of African slaves in its colonies in 1807, and the United States followed in 1808. The British West Indies abolished slavery in 1827 and the French colonies abolished it 15 years later.

In Britain, William Wilberforce took on the cause of abolition in 1787 after the formation of the Committee for the Abolition of the Slave Trade, in which he led the Parliamentary campaign to abolish the slave trade in the British Empire with the Slave Trade Act 1807. He continued to campaign for the abolition of slavery in the British Empire, which he lived to see in the Slavery Abolition Act 1833
In eleven States constituting the American South, slavery was a social and powerful economic institution, integral to the agricultural economy. By the 1860 United States Census, the slave population in the United States had grown to four million.. American abolitionism labored under the handicap that it was accused of threatening the harmony of North and South in the Union. The abolitionist movement in the North was led by social reformers such as William Lloyd Garrison, founder of the American Anti-Slavery Society; writers such as John Greenleaf Whittier and Harriet Beecher Stowe; former slaves such as Frederick Douglass; and free blacks such as brothers Charles Henry Langston and John Mercer Langston, who helped found the Ohio Anti-Slavery Society.

The 1860 presidential victory of Abraham Lincoln, who opposed the spread of slavery to the Western United States, marked a turning point in the movement. Convinced that their way of life was threatened, the Southern states seceded from the Union, which led to the American Civil War. In 1863, Lincoln issued the Emancipation Proclamation, which freed slaves held in the Confederate States; the 13th Amendment to the U.S. Constitution (1865) prohibited slavery throughout the country.

Slavery was abolished in Latin America during the Independence Wars (1810–1822), but slavery remained a practice in the region up to 1888 in Brazil, as well as having long life in the remaining Spanish colonies of Cuba and Puerto Rico. In some parts of Africa and in much of the Islamic world, it persisted as a legal institution well into the 20th century.

Abolitionism was preceded by the New Laws of the Indies in 1542, in which Emperor Charles V declared free all Native American slaves, abolishing slavery of these races, and declaring them citizens of the Empire with full rights. The move was inspired by writings of the Spanish monk Bartolome de las Casas and the School of Salamanca. Spanish settlers replaced the Native American slaves with enslaved laborers brought from Africa, so did not abolish slavery altogether.

Today, child and adult slavery and forced labour are illegal in most countries, as well as being against international law. Because slavery still exists, however, with an estimated 27 million people enslaved worldwide, a new international abolitionist movement has recently emerged.

Slavery in Great Britain

The last known form of enforced servitude of adults (villeinage) had disappeared in Britain at the beginning of the seventeenth century. But by the eighteenth century, traders began to import African and Indian and East Asian slaves to London and Edinburgh to work as personal servants. They were not bought or sold, and their legal status was unclear until 1772, when the case of a runaway slave named James Somersett forced a legal decision. The owner, Charles Steuart, had attempted to abduct him and send him to Jamaica to work on the sugar plantations. While in London, Somersett had been baptised and his godparents issued a writ of habeas corpus. As a result Lord Mansfield, Chief Justice of the Court of the King's Bench, had to judge whether the abduction was legal or not under English Common Law, as there was no legislation for slavery in England.

In his judgment of 22 June 1772, Mansfield declared: "Whatever inconveniences, therefore, may follow from a decision, I cannot say this case is allowed or approved by the law of England; and therefore the black must be discharged." Although the exact legal implications of the judgement are actually unclear when analysed by lawyers, it was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. This judgment emancipated the ten to fourteen thousand slaves or possible slaves in England, who were mostly domestic servants. It also laid down the principle that slavery contracted in other jurisdictions (such as the American colonies) could not be enforced in England.

After reading about the Somersett's Case, an enslaved African in Scotland, Joseph Knight, left his master John Wedderburn. A similar case to Steuart's was brought by Wedderburn in 1776, with the same result: chattel slavery was ruled not to exist under the law of Scotland. Nonetheless, legally mandated, hereditary slavery of Scots in Scotland existed from 1606 until 1799, when colliers and salters were legally emancipated by an act of the Parliament of Great Britain (39 Geo.III. c56). A prior law enacted in 1775 (15 Geo.III. c. 28) was intended to end what the act referred to as "a state of slavery and bondage" but it was ineffectual, necessitating the 1799 act.

First steps

Despite the ending of slavery in Great Britain, slavery was a strong institution in the Southern Colonies of British America and the West Indian colonies of the British Empire. By 1783, an anti-slavery movement was beginning among the British public. That year the first British abolitionist organisation was founded by a group of Quakers. The Quakers continued to be influential throughout the lifetime of the movement, in many ways leading the campaign. On 17 June 1783 the issue was formally brought to government by Sir Cecil Wray (Member of Parliament for Retford), who presented the Quaker petition to parliament. Also in 1783, Dr Beilby Porteus issued a call to the Church of England to cease its involvement in the slave trade and to formulate a workable policy to draw attention to and improve the conditions of Afro-Caribbean slaves. The exploration of the African continent, by such British groups as the African Association (1788), promoted the abolitionists' cause by showing Europeans that the Africans had legitimate, complex cultures. The African Association also had close ties with William Wilberforce, perhaps the most important political figure in the battle for abolition in the British Empire.

Black people also played an important part in the movement for abolition. In Britain, Olaudah Equiano, whose autobiography was published in nine editions in his lifetime, campaigned tirelessly against the slave trade.

Growth of the movement

In May 1787, the Committee for the Abolition of the Slave Trade was formed, referring to the Atlantic slave trade, the trafficking in slaves by British merchants who took manufactured goods from ports such as Bristol and Liverpool, sold or exchanged these for slaves in West Africa where the African chieftain hierarchy was tied to slavery, shipped the slaves to British colonies and other Caribbean countries or the American colonies, where they sold or exchanged them mainly to the Planters for rum and sugar, which they took back to British ports. This was the so-called Triangle trade because these mercantile merchants traded in three places each round-trip. Political influence against the inhumanity of the slave trade grew strongly in the late eighteenth century. Many people, some African, some European by descent, influenced abolition. Well known abolitionists in Britain included James Ramsay who had seen the cruelty of the trade at first hand, Granville Sharp, Thomas Clarkson, and other members of the Clapham Sect of evangelical reformers, as well as Quakers who took most of the places on the Committee for the Abolition of the Slave Trade, having been the first to present a petition against the slave trade to the British Parliament and who founded the predecessor body to the Committee. As Dissenters, Quakers were not eligible to become British MPs in the late eighteenth and early nineteenth century, so the Anglican evangelist William Wilberforce was persuaded to become the leader of the parliamentary campaign. Clarkson became the group's most prominent researcher, gathering vast amounts of information about the slave trade, gaining first hand accounts by interviewing sailors and former slaves at British ports such as Bristol, Liverpool and London.
Mainly because of Clarkson's efforts, a network of local abolition groups was established across the country. They campaigned through public meetings and the publication of pamphlets and petitions. One of the earliest books promoted by Clarkson and the Committee for the Abolition of the Slave Trade was the autobiography of the freed slave Olaudah Equiano. The movement had support from such freed slaves, from many denominational groups such as Swedenborgians, Quakers, Baptists, Methodists and others, and reached out for support from the new industrial workers of the cities in the midlands and north of England. Even women and children, previously un-politicised groups, became involved in the campaign although at this date women often had to hold separate meetings and were ineligible to be represented in the British Parliament, as indeed were the majority of the men in Britain.

One particular project of the abolitionists was the negotiation with African chieftains for the purchase of land in West African kingdoms for the establishment of 'Freetown' – a settlement for former slaves of the British Empire and the United States, back in west Africa. This privately negotiated settlement, later part of Sierra Leone eventually became protected under a British Act of Parliament in 1807–8, after which British influence in West Africa grew as a series of negotiations with local Chieftains were signed to stamp out trading in slaves. These included agreements to permit British navy ships to intercept Chieftains' ships to ensure their merchants were not carrying slaves.
In 1796, John Gabriel Stedman published the memoirs of his five-year voyage to Surinam as part of a military force sent out to subdue bosnegers, former slaves living in the inlands. The book is critical of the treatment of slaves and contains many images by William Blake and Francesco Bartolozzi depicting the cruel treatment of runaway slaves. It became part of a large body of abolitionist literature.

Slave Trade Act 1807

The Slave Trade Act was passed by the British Parliament on 25 March 1807, making the slave trade illegal throughout the British Empire. The Act imposed a fine of £100 for every slave found aboard a British ship. Such a law was bound to be eventually passed, given the increasingly powerful abolitionist movement. The timing might have been connected with the Napoleonic Wars raging at the time. At a time when Napoleon took the retrograde decision to revive slavery which had been abolished during the French Revolution and to send his troops to re-enslave the people of Haiti and the other French Caribbean possessions, the British prohibition of the slave trade gave the British Empire the high moral ground.

The act's intention was to entirely outlaw the slave trade within the British Empire, but the trade continued and captains in danger of being caught by the Royal Navy would often throw slaves into the sea to reduce the fine. In 1827, Britain declared that participation in the slave trade was piracy and punishable by death. Between 1808 and 1860, the Royal Navy's West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade, for example against "the usurping King of Lagos", deposed in 1851. Anti-slavery treaties were signed with over 50 African rulers.

Slavery Abolition Act 1833

After the 1807 act, slaves were still held, though not sold, within the British Empire. In the 1820s, the abolitionist movement again became active, this time campaigning against the institution of slavery itself. In 1823 the first Anti-Slavery Society was founded in Britain. Many of the campaigners were those who had previously campaigned against the slave trade. Sam Sharpe contributed to the abolition of slavery with his Christmas rebellion in 1831.

On 28 August 1833, the Slavery Abolition Act was given Royal Assent, which paved the way for the abolition of slavery within the British Empire and its colonies. On 1 August 1834, all slaves in the British Empire were emancipated, but they were indentured to their former owners in an apprenticeship system which was abolished in two stages; the first set of apprenticeships came to an end on 1 August 1838, while the final apprenticeships ended two years later on 1 August 1840.

On the 1st of August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House in Port of Spain, Trinidad, about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August, 1838, making Trinidad the first British colony with slaves to completely abolish slavery.
The government set aside £20 million to cover compensation of slave owners across the Empire, but the former slaves received no compensation or reparations.

Campaigning after the act

In 1839, a successor organisation to the Anti-Slavery Society was formed, the British and Foreign Anti-Slavery Society, which worked to outlaw slavery in other countries and also to pressure the government to help enforce the suppression of the slave trade by declaring slave traders pirates and pursuing them. This organisation continues today as Anti-Slavery International.

France

As in other "New World" colonies, the Atlantic slave trade provided the French colonies with manpower for the sugar cane plantations. The French West Indies included Anguilla (briefly), Antigua and Barbuda (briefly), Dominica, Dominican Republic, Grenada, Haïti, Montserrat (briefly), Saint Lucia, Saint Vincent and the Grenadines, Sint Eustatius (briefly), St Kitts and Nevis (St Kitts, but not Nevis), Trinidad and Tobago (Tobago only), Saint Croix (briefly), and the current French overseas départements of Martinique and Guadeloupe (including Saint-Barthélemy and northern half of Saint Martin) in the Caribbean sea.
The slave trade was regulated by Louis XIV's Code Noir. The revolt of slaves in the largest French colony of St. Domingue in 1791 was the beginning of what became the Haïtian Revolution led by Toussaint L'Ouverture. The institution of slavery was first abolished in St. Domingue in 1793 by Sonthonax, who was the Commissioner sent to St. Domingue by the Convention, after the slave revolt of 1791, in order to safeguard the allegiance of the population to revolutionary France. The Convention, the first elected Assembly of the First Republic (1792–1804), then abolished slavery in law in France and its colonies on 4 February 1794. Abbé Grégoire and the Society of the Friends of the Blacks (Société des Amis des Noirs), led by Jacques Pierre Brissot, were part of the abolitionist movement, which had laid important groundwork in building anti-slavery sentiment in the metropole. The first article of the law stated that "Slavery was abolished" in the French colonies, while the second article stated that "slave-owners would be indemnified" with financial compensation for the value of their slaves. The constitution of France passed in 1795 included in the declaration of the Rights of Man that slavery was abolished.

However, Napoleon did not include any declaration of the Rights of Man in the Constitution promulgated in 1799, and decided to re-establish slavery after becoming First Consul, promulgating the law of 20 May 1802 and sending military governors and troops to the colonies to impose it. On 10 May 1802, Colonel Delgrès launched a rebellion in Guadeloupe against Napoleon's representative, General Richepanse. The rebellion was repressed, and slavery was re-established. The news of this event sparked the rebellion that led to the loss of the lives of tens of thousands of French soldiers, a greater loss of civilian lives, and Haïti's gaining independence in 1804, and the consequential loss of the second most important French territory in the Americas, Louisiana, which was sold to the United States of America. The French governments refused to recognise Haiti and only did so in the 1830s when Haiti agreed to pay a substantial amount of reparations. Then, on 27 April 1848, under the Second Republic (1848–52), the decree-law Schœlcher again abolished slavery. The state bought the slaves from the colons (white colonists; Békés in Creole), and then freed them.
At about the same time, France started colonising Africa. Its activities there included transferring the population to mines, forestry, and rubber plantations under isolated, harsh working conditions often compared to slavery.

Debates about the dimensions of colonialism continue. On 10 May 2001, the Taubira law officially acknowledge slavery and the Atlantic Slave Trade as a crime against humanity. 10 May was chosen as the day dedicated to recognition of the crime of slavery. Anti-colonial activists also want the French Republic to recognise African Liberation Day.

Although the crime of slavery was formally recognised, four years later, the conservative Union for a Popular Movement (UMP) voted on 23 February 2005 for a law to require teachers and textbooks to "acknowledge and recognise in particular the positive role of the French presence abroad, especially in North Africa." This resolution was met with public uproar and accusations of historic revisionism, both inside France and abroad. Because of this law, Abdelaziz Bouteflika, president of Algeria, refused to sign the envisioned "friendly treaty" with France. Famous writer Aimé Césaire, leader of the Négritude movement, refused to meet UMP leader Nicolas Sarkozy, who cancelled his planned visit to Martinique. President Jacques Chirac (UMP) repealed the controversial law at the beginning of 2006.

Wallachia and Moldavia

In the principalities of Wallachia and Moldavia (both now part of Romania), the enslavement of the Roma (often referred to as Gypsies) was still legal at the beginning of the 19th century. Abolitionism was associated with the progressive pro-European and anti-Ottoman movement, which gradually gained power in the two principalities. Between 1843 and 1855, all of the 250,000 enslaved Roma people were liberated. Many migrated to Western Europe and North America.

United States

Gradual emancipation

The first American movement to abolish slavery came in the spring of 1688 when German and Dutch Quakers of Mennonite descent in Germantown, Pennsylvania (now part of Philadelphia) wrote a two-page condemnation of the practice and sent it to the governing bodies of their Quaker church, the Society of Friends. Though the Quaker establishment took no immediate action, the 1688 Germantown Quaker Petition Against Slavery, was an unusually early, clear and forceful argument against slavery and initiated the process of banning slavery in the Society of Friends (1776) and Pennsylvania(1780).
The Society for the Relief of Free Negroes Unlawfully Held in Bondage was the first American abolition society, formed 14 April 1775, in Philadelphia, primarily by Quakers who had strong religious objections to slavery. Rhode Island Quakers, associated with Moses Brown, co-founder of Brown University, and who also settled at Uxbridge, Massachusetts prior to 1770, were among the first in America to free slaves. The society ceased to operate during the Revolution and the British occupation of Philadelphia. After the Revolution, it was reorganized in 1784, with Benjamin Franklin as its first president. 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. The first article published in what later became the United States advocating the emancipation of slaves and the abolition of slavery was allegedly written by Thomas Paine. Titled "African Slavery in America", it appeared on 8 March 1775 in the Postscript to the Pennsylvania Journal and Weekly Advertiser, more popularly known as The Pennsylvania Magazine, or American Museum.

Abolitionist Movement

The Abolitionist Movement set in motion actions in every state to abolish slavery. By 1804, abolitionists succeeded in passing legislation that would eventually (in conjunction with the 13th amendment) emancipate the slaves in every state north of the Ohio River and the Mason-Dixon Line. However, emancipation in the free states was so gradual that there were still a dozen "permanent apprentices" in the 1860 census.
The principal organized bodies to advocate this reform were the Society of Friends, the Pennsylvania Antislavery Society and the New York Manumission Society. The last was headed by powerful Federalist politicians: John Jay, Alexander Hamilton and Republican Aaron Burr. Thanks to the considerable efforts of the NYMS, New York abolished slavery (gradually) in 1799. In terms of numbers of slaves, this was the largest emancipation in American history (before 1863). New Jersey in 1804 was the last northern state to abolish slavery (again in gradual fashion). At the Constitutional Convention of 1787, agreement was reached that allowed the Federal government to abolish the international slave trade, but not prior to 1808. By that time, all the states had passed individual laws abolishing or severely limiting the trade, all but Georgia by 1798; some of the Southern laws were later repealed.

After the American Revolutionary War, Quaker and Moravian advocates helped persuade numerous slaveholders in the Upper South to free their slaves. Manumissions increased for nearly two decades. Many individual acts of manumission freed thousands of slaves in total. Slaveholders freed slaves in such number that the percentage of free Negroes in the Upper South increased sharply from one to ten percent, with most of that increase in Virginia, Maryland and Delaware. By 1810 three-quarters of blacks in Delaware were free. The most notable of individuals was Robert Carter III of Virginia, who freed more than 450 people by "Deed of Gift", filed in 1791. This number was more slaves than any single American had freed or would ever free. Often slaveholders came to their decisions by their own struggles in the Revolution; their wills and deeds frequently cited language about the equality of men supporting their manumissions. Slaveholders were also encouraged to do so because the economics of the area was changing. They were shifting from labor-intensive tobacco culture to mixed crop cultivation and did not need as many slaves.Peter Kolchin, American Slavery, 1619–1877, New York: Hill and Wang, 1994, pp.78, 81–82
The free black families began to thrive, together with African Americans free before the Revolution, mostly descendants of unions between working class white women and African men. By 1860, in Delaware 91.7 percent of the blacks were free, and 49.7 percent of those in Maryland. These first free families often formed the core of artisans, professionals, preachers and teachers in future generations.
The importation of slaves into the United States was officially banned on 1 January 1808. but not its internal slave trade until 1850, which District of Columbia banned as part of the Compromise of 1850.

John Brown (1800–1859), abolitionist who advocated armed insurrection to overthrow the institution of slavery. He organized the Pottawatomie Massacre (1856) and was later executed for leading an unsuccessful 1859 raid on Harpers Ferry, West Virginia.

During the Congressional debate on the 1820 Tallmadge Amendment, which sought to limit slavery in Missouri as it became a state, Rufus King declared that "laws or compacts imposing any such condition [slavery] upon any human being are absolutely void, because contrary to the law of nature, which is the law of God, by which he makes his ways known to man, and is paramount to all human control." The amendment failed and Missouri became a slave state. According to historian David Brion Davis, this may have been the first time in the world that a political leader openly attacked slavery’s perceived legality in such a radical manner.

Beginning in the 1830s, the U.S. Postmaster General refused to allow the mails to carry abolition pamphlets to the South. Northern teachers suspected of abolitionism were expelled from the South, and abolitionist literature was banned. Southerners rejected the denials of Republicans that they were abolitionists. They pointed to John Brown's attempt in 1859 to start a slave uprising as proof that multiple Northern conspiracies were afoot to ignite bloody slave rebellions. Although some abolitionists did call for slave revolts, no evidence of any other Brown-like conspiracy has been discovered. The North felt threatened as well, for as Eric Foner concludes, "Northerners came to view slavery as the very antithesis of the good society, as well as a threat to their own fundamental values and interests". However, many conservative Northerners were uneasy at the prospect of the sudden addition to the labor pool of a huge number of freed laborers who were used to working for very little, and thus seen as being willing to undercut prevailing wages.. The famous, "fiery" Abolitionist, Abby Kelley Foster, from Massachusetts, was considered an "ultra" abolitionist who believed in full civil rights for all black people. She held to the views that the freed slaves would colonize Liberia. Parts of the anti-slavery movement became known as "Abby Kellyism". She recruited Susan B Anthony to the movement.

Colonization and the founding of Liberia

Henry Clay (1777–1852), one of the three founders of the American Colonization Society.

In the early part of the 19th century, a variety of organizations were established advocating the movement of black people from the United States to locations where they would enjoy greater freedom; some endorsed colonization, while others advocated emigration. During the 1820s and 1830s the American Colonization Society (A.C.S.) was the primary vehicle for proposals to return black Americans to freedom in Africa. It had broad support nationwide among white people, including prominent leaders such as Abraham Lincoln, Henry Clay and James Monroe, who saw this as preferable to emancipation, with Clay believing: “unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country". There was however, considerable opposition among African Americans, many of whom did not see colonization as a viable or acceptable solution to their daunting problems in the United States. One notable opponent of such plans was the wealthy free black abolitionist James Forten of Philadelphia.

After a series of attempts to plant small settlements on the coast of West Africa, the A.C.S. established the colony of Liberia in 1821–22. Over the next four decades, it assisted thousands of former slaves and free black people to move there from the United States. The disease environment they encountered was extreme, and most of the migrants died fairly quickly. Enough survived to declare independence in 1847. American support for colonization waned gradually through the 1840s and 1850s, largely because of the efforts of abolitionists to promote emancipation of slaves and granting of American citizenship. Americo-Liberians ruled Liberia continuously until the military coup of 1980.

Emigration

The emigrationist tradition dated back to the Revolutionary War era. Initially, the thought was that free African Americans would want to emigrate to Africa, but over time other ideas became popular. After Haiti became independent, it tried to recruit African Americans to migrate there after it re-established trade relations with the United States. The Haytian Union was the name of a group formed to promote relations between the countries.Taylor, Nikki M. Frontiers of Freedom: Cincinnati's Black Community, 1802–1868. Ohio University Press, 2005, ISBN 0-8214-1579-4, pp. 50–79.
Cincinnati's Black community sponsored founding the Wilberforce Colony, an initially successful settlement of African American immigrants to Canada. The colony was one of the first such independent political entities. It lasted for a number of decades and provided a destination for black Americans emigrating from a number of locations in the United States.

Garrison and immediate emancipation

William Lloyd Garrison (1805–1879), publisher of the abolitionist newspaper The Liberator and one of the founders of the American Anti-Slavery Society.

A radical shift came in the 1830s, led by William Lloyd Garrison, who demanded "immediate emancipation, gradually achieved". That is, he demanded that slave-owners repented immediately, and set up a system of emancipation. Theodore Weld, an evangelical minister, and Robert Purvis, a free African American, joined Garrison in 1833 to form the Anti-Slavery Society (Faragher 381). The following year Weld encouraged a group of students at Lane Theological Seminary to form an anti-slavery society. After the president, Lyman Beecher, attempted to suppress it, the students moved to Oberlin College. Due to the students' anti-slavery position, Oberlin soon became one of the most liberal colleges and accepted African American students. Along with Garrison, were Northcutt and Collins as proponents of immediate abolition. These two ardent abolitionists felt very strongly that it could not wait and that action needed to be taken right away.

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.

After 1840 "abolition" usually referred to positions like Garrison's; it was largely an ideological movement led by about 3000 people, including free blacks and people of color, many of whom, such as Frederick Douglass, and Robert Purvis and James Forten in Philadelphia, played prominent leadership roles. Abolitionism had a strong religious base including Quakers, and people converted by the revivalist fervor of the Second Great Awakening, led by Charles Finney in the North in the 1830s. Belief in abolition contributed to the breaking away of some small denominations, such as the Free Methodist Church.
Evangelical abolitionists founded some colleges, most notably Bates College in Maine and Oberlin College in Ohio. The well-established colleges, such as Harvard, Yale and Princeton, generally opposed abolition, although the movement did attract such figures as Yale president Noah Porter and Harvard president Thomas Hill.

In the North, most opponents of slavery supported other modernizing reform movements such as the temperance movement, public schooling, and prison- and asylum-building. They split bitterly on the role of women's activism.
Daniel O'Connell, the Roman Catholic leader of the Irish in Ireland, supported the abolition of slavery in the British Empire and in America. O'Connell had played a leading role in securing Catholic Emancipation (the removal of the civil and political disabilities of Roman Catholics in Great Britain and Ireland) and he was one of William Lloyd Garrison's models. Garrison recruited him to the cause of American abolitionism. O'Connell, the black abolitionist Charles Lenox Remond, and the temperance priest Theobold Mayhew organized a petition with 60,000 signatures urging the Irish of the United States to support abolition. O'Connell also spoke in the United States for abolition.

The Repeal Associations in the United States mostly took a pro-slavery position. Several reasons have been suggested for this: that Irish immigrants were competing with free blacks for jobs, and disliked having the same arguments used for Irish and for black freedom; that they were loyal to the United States Constitution, which defended their liberties, and disliked the fundamentally extra-constitutional position of the Abolitionists; and that they perceived abolitionism as Protestant, and were therefore suspicious of them. In addition, slaveholders had no hesitation in voicing their support for the freedom of Ireland, a white nation outside the United States.

Radical Irish nationalists – those who broke with O'Connell over his refusal to contemplate the violent overthrow of British rule in Ireland – had a diversity of views about slavery. John Mitchel, who spent the years 1853 to 1875 in America, was a passionate propagandist in favor of slavery; three of his sons fought in the Confederate Army. On the other hand, his former close associate Thomas Francis Meagher served as a Brigadier General in the United States Army during the American Civil War.

The Catholic Church in America had long ties in slaveholding Maryland and Louisiana. Despite a firm stand for the spiritual equality of black people, and the resounding condemnation of slavery by Pope Gregory XVI in his bull In Supremo Apostolatus issued in 1839, the American church continued in deeds, if not in public discourse, to support slaveholding interests. The Bishop of New York denounced O'Connell's petition as a forgery, and if genuine, an unwarranted foreign interference. The Bishop of Charleston declared that, while Catholic tradition opposed slave trading, it had nothing against slavery. No American bishop supported abolition before the Civil War. While the war went on, they continued to allow slave-owners to take communion.

One historian observed that ritualist churches separated themselves from heretics rather than sinners; he observed that Episcopalians and Lutherans also accommodated themselves to slavery. (Indeed, one southern Episcopal bishop was a Confederate general.) There were more reasons than religious tradition, however, as the Anglican Church had been the established church in the South during the colonial period. It was linked to the traditions of landed gentry and the wealthier and educated planter classes, and the Southern traditions longer than any other church. In addition, while the Protestant missionaries of the Great Awakening initially opposed slavery in the South, by the early decades of the 19th century, Baptist and Methodist preachers in the South had come to an accommodation with it in order to evangelize with farmers and artisans. By the Civil War, the Baptist and Methodist churches split into regional associations because of slavery.

After O'Connell's failure, the American Repeal Associations broke up; but the Garrisonians rarely relapsed into the "bitter hostility" of American Protestants towards the Roman Church. Some antislavery men joined the Know Nothings in the collapse of the parties; but Edmund Quincy ridiculed it as a mushroom growth, a distraction from the real issues. Although the Know-Nothing legislature of Massachusetts honored Garrison, he continued to oppose them as violators of fundamental rights to freedom of worship.

First edition Uncle Tom's Cabin, 1852, USA edition; published simultaneously on both sides of the Atlantic by American author Harriet Beecher Stowe and with an introduction by the English pastor Rev James Sherman, the novel caught the public imagination just at a turning point in popular support for American abolition.

Abolitionists like William Lloyd Garrison repeatedly condemned slavery for contradicting the principles of freedom and equality on which the country was founded. In 1854, Garrison wrote:

I am a believer in that portion of the Declaration of American Independence in which it is set forth, as among self-evident truths, "that all men are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness." Hence, I am an abolitionist. Hence, I cannot but regard oppression in every form – and most of all, that which turns a man into a thing – with indignation and abhorrence. Not to cherish these feelings would be recreancy to principle. They who desire me to be dumb on the subject of slavery, unless I will open my mouth in its defense, ask me to give the lie to my professions, to degrade my manhood, and to stain my soul. I will not be a liar, a poltroon, or a hypocrite, to accommodate any party, to gratify any sect, to escape any odium or peril, to save any interest, to preserve any institution, or to promote any object. Convince me that one man may rightfully make another man his slave, and I will no longer subscribe to the Declaration of Independence. Convince me that liberty is not the inalienable birthright of every human being, of whatever complexion or clime, and I will give that instrument to the consuming fire. I do not know how to espouse freedom and slavery together.

History of abolition in the United States

In The Struggle for Equality, historian James M. McPherson defines an abolitionist "as one who before the Civil War in the United States had agitated for the immediate, unconditional, and total abolition of slavery in the United States."

Although there were several groups that opposed slavery (such as the Society for the Relief of Free Negroes Unlawfully Held in Bondage), at the time of the founding of the Republic, there were few states which prohibited slavery outright. The Constitution had several provisions which accommodated slavery, although none used the word. Passed unanimously by the Congress of the Confederation in 1787, the Northwest Ordinance forbade slavery in the Northwest Territory, a vast area which had previously belonged to individual states in which slavery was legal.

Samuel Sewall (1652-1730), judge who wrote The Selling of Joseph (1700) which denounced the spread of slavery in the American colonies.

American abolitionism began very early, well before the United States was founded as a nation. An early law abolishing slavery (but not temporary indentured servitude) in Rhode Island in 1652 floundered within 50 years. Samuel Sewall, a prominent Bostonian and one of the judges at the Salem Witch Trials, wrote 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.

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. McPherson describes three types of abolitionists prior to the Civil War:

On the ideological spectrum, from immediate abolition on the Left to conservative antislavery on the Right, it is often hard to tell where "abolition" (which demanded unconditional emancipation and usually envisaged civil equality for the free slaves.) ended and "antislavery" or "free soil" (which desired only the containment of slavery and was ambivalent on the question of equality) began. In New England particularly, many free soilers were abolitionists at heart; in the mid-Atlantic states and even more in the old Northwest, political abolitionists tended to submerge their abolitionist identity in the broader but shallower stream of free soil.

Vermont was the first territory (not a state at the time) in North America to prohibit slavery in 1777. It did not actually free slaves, but required masters to remove them from the territory. The first state to begin a gradual abolition of slavery was Pennsylvania in 1780, although the process was very gradual. All importation of slaves was prohibited, but it freed no one at first; only the slaves of masters who failed to register them with the state, along with the future children of enslaved mothers. Those enslaved in Pennsylvania before the 1780 law went into effect were not freed until 1847.

Massachusetts took an opposite and much more radical position. Its Supreme Court ruled in 1783, that a black man was, indeed, a man; and therefore free under the state's constitution.

All of the other states north of Maryland began gradual abolition of slavery between 1781 and 1804, based on the Pennsylvania model. Rhode Island had limited slave trading in 1774 (Virginia had also attempted to do so before the Revolution, but the Privy Council had vetoed the act), all the other northern states also limited the slave trade by 1786, and Georgia in 1798. These northern emancipation acts typically provided that slaves born before the law was passed would be freed at a certain age, and so remnants of slavery lingered; in New Jersey, a dozen "permanent apprentices" were recorded in the 1860 census.

The institution remained solid in the South, however and that region's customs and social beliefs evolved into a strident defense of slavery in response to the rise of a stronger anti-slavery stance in the North. In 1835 alone abolitionists mailed over a million pieces of anti-slavery literature to the south. In response southern legislators banned abolitionist literature and encouraged harassment of anyone distributing it. Anti-slavery sentiment among many people in the North was jolted by the murder of Elijah Parish Lovejoy, a white man and editor of an abolitionist newspaper on 7 November 1837, by a pro-slavery mob which destroyed his printing press. The majority of Northerners rejected the extreme positions of the abolitionists; Abraham Lincoln, for example. Indeed many northern leaders including Lincoln, Stephen Douglas (the Democratic nominee in 1860), John C. Fremont (the Republican nominee in 1856), and Ulysses S. Grant married into slave owning southern families without any moral qualms.

Abolitionism 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 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.

Lysander Spooner (1808-1887), an individualist anarchist who wrote The Unconstitutionality of Slavery (1845).

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.

Another split in the abolitionist movement was along class lines. The artisan republicanism of Robert Dale Owen and Frances Wright stood in stark contrast to the politics of prominent elite abolitionists such as industrialist Arthur Tappan and his evangelist brother Lewis. While the former pair opposed slavery on a basis of solidarity of "wage slaves" with "chattel slaves", the Whiggish Tappans strongly rejected this view, opposing the characterization of Northern workers as "slaves" in any sense. (Lott, 129–130)

Many American abolitionists took an active role in opposing slavery by supporting the Underground Railroad. This was made illegal by the federal Fugitive Slave Law of 1850. Nevertheless, participants like Harriet Tubman, Henry Highland Garnet, Alexander Crummell, Amos Noë Freeman and others continued with their work. Abolitionists were particularly active in Ohio, where some worked directly in the Underground Railroad. Since the state shared a border with slave states, it was a popular place for slaves' escaping across the Ohio River and up its tributaries, where they sought shelter among supporters who would help them move north to freedom. Two significant events in the struggle to destroy slavery were the Oberlin-Wellington Rescue and John Brown's raid on Harpers Ferry. In the South, members of the abolitionist movement or other people opposing slavery were often targets of lynch mob violence before the American Civil War.

Numerous known abolitionists lived, worked, and worshipped in Downtown Brooklyn, from Henry Ward Beecher, who auctioned slaves into freedom from the pulpit of Plymouth Church, to Nathan Egelston, a leader of the African and Foreign Antislavery Society, who also preached at Bridge Street AME and lived on Duffield Street. His fellow Duffield Street residents, Thomas and Harriet Truesdell were leading members of the Abolitionist movement. Mr. Truesdell was a founding member of the Providence Anti-slavery Society before moving to Brooklyn in 1851. Harriet Truesdell was also very active in the movement, organizing an antislavery convention in Pennsylvania Hall in Philadelphia. The Tuesdell's lived at 227 Duffield Street. Another prominent Brooklyn-based abolitionist was Rev. Joshua Leavitt, trained as a lawyer at Yale who stopped practicing law in order to attend Yale Divinity School, and subsequently edited the abolitionist newspaper The Emancipator and campaigned against slavery, as well as advocating other social reforms. In 1841 Leavitt published his The Financial Power of Slavery, which argued that the South was draining the national economy due to its reliance on slavery.

After the issuance of the Emancipation Proclamation on 1 January 1863, abolitionists continued to pursue the freedom of slaves in the remaining slave states, and to better the conditions of black Americans generally. The passage of the Thirteenth Amendment in 1865 officially ended slavery in the United States.

National abolition dates

Slavery was abolished in these nations in these years:

• Hungary: Stephen I of Hungary, the first Hungarian Christian king, declared in his laws (near 1000) that any slave that lives, stays or enters the territory of the Kingdom of Hungary would become free immediately.

• Sweden: Magnus IV of Sweden declared the end of thralldom in 1335 "for thralls born by Christian parents in the thing areas of Västergötland and Värend". Swedish participation in the transatlantic slave trade was forbidden in 1813, and in 1847, slavery was abolished, after an initial decision taken in 1846. (The last legally owned slaves in the Swedish colony of St Barthélemy were bought by the state and freed on 9 October 1847.)

• Japan: In 1587 Toyotomi Hideyoshi ordered all slave trading to be abolished. His successor Tokugawa Ieyasu also continued abolition of slavery although severe servitude was still in practice until the fall of the Tokugawa Shogunate in the 1860s.

• Portugal: 1761 in Portugal and Portuguese India (1869, African colonies)

• England and Wales: In practice, 1772, as a result of Somersett's case; although the legal effect of this was much more limited; see Slavery at common law

• Scotland: 1799 by an act of the Parliament of Great Britain (39 Geo.III. c. 56).

• Vermont Republic: 1777, Commonwealth of Vermont, an independent republic created after the American Revolution, on 8 July 1777. Vermont joined the United States of America in 1791.

• Bukovina: 1783, Joseph II, Holy Roman Emperor issued an order abolishing slavery on 19 June 1783 in Czernowitz.

• Central Great Lakes Region of the United States: 1787, pre-dating the United States Constitution by the Northwest Ordinance which re-affirmed it in 1789.

• Upper Canada: 1793, by Act Against Slavery (this did not free any slaves, but stated that children of current slaves would become free at age 25)

• France (first time): 1794–1802, including all colonies (although abolition was never carried out in some colonies, because of resistance by local assemblies, or because the colonies were under British occupation)

• Lower Canada: In 1803, William Osgoode, then Chief Justice of Lower Canada, ruled that slavery was not compatible with British law; this freed many slaves, but some remained enslaved until the abolition of slavery in the entire British Empire in 1833

• Chile: 1811 partially, and in 1823 for all who remained as slave and "whoever slave setting a foot on Chilean soil".

• Argentina: 1813

Chinese labourers replaced the African slaves since then and worked on a semi-slavery regime, until they were mostly freed by Chilean troops during the War of the Pacific in 1880. Native Peruvians in some regions of the country continued working on a slavery based regime that had begun as encomiendas during the Spanish rule, and were finally freed by Gen. Juan Velasco in 1969, the year slavery finally ended in Peru.

Commemoration

The abolitionist movements and the abolition of slavery have been commemorated in different ways around the world in modern times. The United Nations General Assembly declared 2004 the International Year to Commemorate the Struggle against Slavery and its Abolition. This proclamation marked the bicentenary of the birth of the first black state, Haiti. Numerous exhibitions, events and research programmes were connected to the initiative.

2007 witnessed major exhibitions in British museums and galleries to mark the anniversary of the 1807 abolition act – 2008 marks the 201st anniversary of the Abolition of the Slave Trade in the British Empire. It also marks the 175th anniversary of the Abolition of Slavery in the British Empire.

The Faculty of Law at the University of Ottawa held a major international conference entitled, "Routes to Freedom: Reflections on the Bicentenary of the Abolition of the Slave Trade," from 14 to 16 March 2008. Actor and human rights activist Danny Glover delivered the keynote speech announcing the creation of two major scholarships intended for University of Ottawa law students specializing in international law and social justice at the conference's gala dinner.

Brooklyn, New York has begun work on commemorating the abolitionist movement in New York.

Contemporary abolitionism

On 10 December 1948, the General Assembly of the United Nations adopted the Universal Declaration of Human Rights. Article 4 states:

No one shall be held in slavery or servitude; slavery and the slave trade shall be prohibited in all their forms.

Although outlawed in most countries, slavery is nonetheless practiced secretly in many parts of the world. Enslavement still takes place in the United States, Europe, and Latin America, as well as parts of Africa, the Middle East, and South Asia. There are an estimated 27 million victims of slavery worldwide. In Mauritania alone, estimates are that up to 600,000 men, women and children, or 20% of the population, are enslaved. Many of them are used as bonded labour.

Modern-day abolitionists have emerged over the last several years, as awareness of slavery around the world has grown, with groups such as Anti-Slavery International, the American Anti-Slavery Group, International Justice Mission, and Free the Slaves working to rid the world of slavery. Zach Hunter, for example, began a movement called Loose Change to Loosen Chains when he was in seventh grade. Also featured on CNN and other national news organizations, Hunter has gone on to help inspire other teens and young adults to take action against injustice with his books, Be the Change and Generation Change.

In the United States, The Action Group to End Human Trafficking and Modern-Day Slavery is a coalition of NGOs, foundations and corporations working to develop a policy agenda for abolishing slavery and human trafficking. Since 1997, the United States Department of Justice has, through work with the Coalition of Immokalee Workers, prosecuted six individuals in Florida on charges of slavery in the agricultural industry. These prosecutions have led to freedom for over 1000 enslaved workers in the tomato and orange fields of South Florida. This is only one example of the contemporary fight against slavery worldwide. Slavery exists most widely in agricultural labor, apparel and sex industries, and service jobs in some regions.

In 2000, the United States passed the Victims of Trafficking and Violence Protection Act (TVPA) "to combat trafficking in persons, especially into the sex trade, slavery, and involuntary servitude." The TVPA also "created new law enforcement tools to strengthen the prosecution and punishment of traffickers, making human trafficking a Federal crime with severe penalties."

The United States Department of State publishes the annual Trafficking in Persons Report, identifying countries as either Tier 1, Tier 2, Tier 2 Watch List or Tier 3, depending upon three factors: "(1) The extent to which the country is a country of origin, transit, or destination for severe forms of trafficking; (2) The extent to which the government of the country does not comply with the TVPA’s minimum standards including, in particular, the extent of the government’s trafficking-related corruption; and (3) The resources and capabilities of the government to address and eliminate severe forms of trafficking in persons."
