Slavery in Great Britain existed and was recognised from before the Roman occupation until the 12th century, when chattel slavery disappeared, at least for a time, after the Norman Conquest. Former slaves merged into the larger body of serfs in Britain and no longer were recognized separately in law or custom.
From the 17th century into the 19th century, transportation to the colonies as a criminal or an indentured servant served as punishment for both serious and petty crimes, or for simply being poor and viewed as an 'undesirable', facilitated by the Transportation Act of 1717. During the same period, workhouses employed people whose poverty left them no other alternative than to work under forced labour conditions.

International slave trade
Britain exported slaves from pre-Roman times, but British merchants became major participants in the Atlantic slave trade in the early modern period. Then British people living within the British Isles, as well as in British colonies, might own African slaves. In a triangular trade-system, ship-owners transported enslaved West Africans, as well as British natives, to the New World
(especially to the Caribbean) to be sold there. The ships brought
commodities back to Britain then exported goods to Africa. Some
entrepreneurs brought slaves to Britain, where they were kept in bondage. After a long campaign for abolition led by Thomas Clarkson and (in the House of Commons) by William Wilberforce, Parliament prohibited dealing in slaves by passing the Slave Trade Act 1807, which the Royal Navy's West Africa Squadron
enforced. Britain used its influence to persuade other countries around
the world to abolish the slave trade and to sign treaties to allow the
Royal Navy to interdict slaving ships. However, the British economy
continued to benefit from slavery for many years.
Abolition
Somersett's case in 1772 held that slavery had no basis in English law and was thus a violation of Habeas Corpus. This built on the earlier Cartwright case
from the Reign of Elizabeth I which had similarly held the concept of
slavery was not recognised in English law. This case was generally taken
at the time to have decided that the condition of slavery did not exist
under English law.
Legally ("de jure") slave owners could not win in court, and
abolitionists provided legal help for enslaved black people. However
actual ("de facto") slavery continued in Britain with ten to fourteen
thousand slaves in England and Wales, who were mostly domestic servants.
When slaves were brought in from the colonies they had to sign waivers
that made them indentured servants while in Britain. Most modern
historians generally agree that slavery continued in Britain into the
late 18th century, finally disappearing around 1800. Slavery elsewhere in the British Empire
was not affected--indeed it grew rapidly especially in the Caribbean
colonies. Slavery was abolished by buying out the owners in 1833 by the
Slavery Abolition Act 1833. Most slaves were freed, with exceptions and delays provided for the East India Company, Ceylon, and Saint Helena. These exceptions were eliminated in 1843.
The prohibition on slavery and servitude is now codified under Article 4 of the European Convention on Human Rights, in force since 1953 and incorporated directly into United Kingdom law by the Human Rights Act 1998.
Article 4 of the Convention also bans forced or compulsory labour, with
some exceptions such as a criminal penalty or military service.
Before 1066
From before Roman times, slavery was normal in Britain, with slaves being routinely exported. Slavery continued as an accepted part of society under the Roman Empire and after; Anglo-Saxons continued the slave system, sometimes in league with Norse traders often selling slaves to the Irish. In 870, Vikings besieged and captured the stronghold of Alt Clut (the capital of the Kingdom of Strathclyde) and in 871 took most of the site's inhabitants, most likely by Olaf the White and Ivar the Boneless, to the Dublin slave markets. Maredudd ab Owain (d. 999) paid a large ransom for 2,000 Welsh slaves, which demonstrates the large-scale slave raiding upon the British Isles. Vikings traded with the Gaelic, Pictish, Brythonic and Saxon kingdoms in between raiding them for slaves.
Some of the earliest accounts of the Anglo-Saxon English comes from the account of the fair-haired boys from York seen in Rome by Pope Gregory the Great. In the 7th century the English slave Balthild rose to be queen of the Frankish king Clovis II. Anglo-Saxon opinion turned against the sale of English abroad: a law of Ine of Wessex stated that anyone selling his own countryman, whether bond or free, across the sea, was to pay his own weregild in penalty, even when the man so sold was guilty of crime.
Nevertheless, legal penalties and economic pressures that led to
default in payments maintained the supply of slaves, and in the 11th
century there was still a slave trade operating out of Bristol, as a passage in the Vita Wulfstani makes clear.
Norman England
According to the Domesday Book census, over 10% of England's population in 1086 were slaves. In 1102, the Church Council of London convened by Anselm
issued a decree: "Let no one dare hereafter to engage in the infamous
business, prevalent in England, of selling men like animals." However, the Council had no legislative powers, and no act of law was valid unless signed by the monarch.
The influence of the new Norman aristocracy
led to the decline of slavery in England. Contemporary writers noted
that the Scottish and Welsh took captives as slaves during raids, a
practice which was no longer common in England by the 12th century. By
the start of the 13th century references to people being taken as slaves
stopped. While there was no legislation against slavery, William the Conqueror introduced a law preventing the sale of slaves overseas. According to historian John Gillingham, by about 1200 slavery in the British Isles was non-existent.
Transportation
Transportation to the colonies as a criminal or an indentured servant
served as punishment for both great and petty crimes in England from
the 17th century until well into the 19th century. A sentence could be
for life or for a specific period. The penal system required convicts to
work on government projects such as road construction, building works
and mining, or assigned them to free individuals as unpaid labour. Women
were expected to work as domestic servants and farm labourers. Like
slaves, indentured servants could be bought and sold, could not marry
without the permission of their owner, were subject to physical
punishment, and saw their obligation to labour enforced by the courts.
However, they did retain certain heavily restricted rights; this
contrasts with slaves who had none.
A convict who had served part of his time might apply for a
"ticket of leave", granting them some prescribed freedoms. This enabled
some convicts to resume a more normal life, to marry and raise a family,
and enabled a few to develop the colonies while removing them from the
society.
Exile was an essential component, and was thought to be a major
deterrent to crime. Transportation was also seen as a humane and
productive alternative to execution, which would most likely have been the sentence for many if transportation had not been introduced.
The transportation of English subjects overseas can be traced back to the English Vagabonds Act 1597. During the reign of Henry VIII, an estimated 72,000 people were put to death for a variety of crimes. An alternative practice, borrowed from the Spanish, was to commute
the death sentence and allow the use of convicts as a labour force for
the colonies. One of the first references to a person being transported
comes in 1607 when "an apprentice dyer was sent to Virginia from Bridewell for running away with his master's goods." The Act was little used despite attempts by James I who, with limited success, tried to encourage its adoption by passing a series of Privy Council Orders in 1615, 1619 and 1620.
Transportation was seldom used as a criminal sentence until the Piracy Act 1717,
"An Act for the further preventing Robbery, Burglary, and other
Felonies, and for the more effectual Transportation of Felons, and
unlawful Exporters of Wool; and for declaring the Law upon some Points
relating to Pirates", established a seven-year penal transportation as a
possible punishment for those convicted of lesser felonies, or as a
possible sentence to which capital punishment might be commuted by royal
pardon. Criminals were transported to North America from 1718 to 1776.
When the American revolution made transportation to the Thirteen
Colonies unfeasible, those sentenced to it were typically punished with
imprisonment or hard labour instead. From 1787 to 1868, criminals
convicted and sentenced under the Act were transported to the colonies
in Australia.
After the Irish Rebellion of 1641 and subsequent Cromwellian invasion, the English Parliament passed the Act for the Settlement of Ireland 1652
which classified the Irish population into several categories according
to their degree of involvement in the uprising and the subsequent war.
Those who had participated in the uprising or assisted the rebels in any
way were sentenced to be hanged and to have their property confiscated.
Other categories were sentenced to banishment with whole or partial
confiscation of their estates. While the majority of the resettlement
took place within Ireland to the province of Connaught, perhaps as many as 50,000 were transported to the colonies in the West Indies and in North America.
During the early colonial period, the Scots and the English, along with
other western European nations, dealt with their "Gypsy problem" by
transporting them as slaves in large numbers to North America and the
Caribbean. Cromwell shipped Romanichal Gypsies as slaves to the southern
plantations, and there is documentation of Gypsies being owned by
former black slaves in Jamaica.
Long before the Highland Clearances, some chiefs, such as Ewen Cameron of Lochiel,
sold some of their clans into indenture in North America. Their goal
was to alleviate over-population and lack of food resources in the
glens.
Numerous Highland Jacobite supporters, captured in the aftermath of the Battle of Culloden and rigorous Government sweeps of the Highlands, were imprisoned on ships on the River Thames. Some were sentenced to transportation to the Carolinas as indentured servants.
Slavery and bondage in Scottish collieries
For nearly two hundred years in the history of coal mining in Scotland, miners were bonded to their "maisters" by a 1606 Act "Anent Coalyers and Salters". The Colliers and Salters (Scotland) Act 1775
stated that "many colliers and salters are in a state of slavery and
bondage" and announced emancipation; those starting work after 1 July
1775 would not become slaves, while those already in a state of slavery
could, after 7 or 10 years depending on their age, apply for a decree of
the Sheriff's Court granting their freedom. Few could afford this,
until a further law in 1799 established their freedom and made this
slavery and bondage illegal.
Workhouse slavery
From the 17th century to the 19th century, workhouses took in people
whose poverty left them no other alternative. They were employed under
forced labour conditions. Workhouses took in abandoned babies, usually
presumed to be illegitimate. When they grew old enough, they were used
as child labour. Charles Dickens represented such issues in his fiction. A life example was Henry Morton Stanley.
This was a time when many children worked; if families were poor,
everyone worked. Only in 1833 and 1844 were the first general protective
laws against child labour, the Factory Acts, passed in Britain.
Barbary pirates
From the 16th to the 19th centuries it is estimated that between 1 million and 1.25 million Europeans were captured by Barbary pirates and Barbary slave traders and sold as slaves. The slavers got their name from the Barbary Coast,
that is, the Mediterranean shores of North Africa – what is now
Morocco, Algeria, Tunisia, and Libya. There are reports of Barbary raids
and kidnappings of those in France, Ireland, Italy, Portugal, Spain,
and the United Kingdom and as far north as Iceland and the fate of those
abducted into slavery in North Africa and the Ottoman Empire.
Villagers along the south coast of England petitioned the king to
protect them from abduction by Barbary pirates. Item 20 of The Grand Remonstrance, a list of grievances against Charles I
presented to him in 1641, contains the following complaint about
Barbary pirates of the Ottoman Empire abducting English people into
slavery:
And although all this was taken upon pretense of guarding the seas, yet a new unheard-of tax of ship-money was devised, and upon the same pretense, by both which there was charged upon the subject near £700,000 some years, and yet the merchants have been left so naked to the violence of the Turkish pirates, that many great ships of value and thousands of His Majesty's subjects have been taken by them, and do still remain in miserable slavery.
Enslaved Africans
Admiral Sir John Hawkins of Plymouth, a notable Elizabethan
seafarer, is widely acknowledged to be "the Pioneer of the English
Slave Trade". In 1554–1555, Hawkins formed a slave trading syndicate of
wealthy merchants. He sailed with three ships for the Caribbean via Sierra Leone, hijacked a Portuguese slave ship and sold the 300 slaves from it in Santo Domingo. During a second voyage in 1564, his crew captured 400 Africans and sold them at Rio de la Hacha
in present-day Colombia, making a 60% profit for his financiers. A
third voyage involved both buying slaves directly in Africa and
capturing a Portuguese ship with its cargo; upon reaching the Caribbean,
Hawkins sold all the slaves. On his return, he published a book
entitled An Alliance to Raid for Slaves.
It is estimated that Hawkins transported 1,500 enslaved Africans across
the Atlantic during his four voyages of the 1560s, before stopping in
1568 after a battle with the Spanish in which he lost five of his seven
ships. The English involvement in the Atlantic slave trade only resumed
in the 1640s after the country acquired an American colony (Virginia).
By the mid 18th century, London had the largest African
population in Britain, made up of free and enslaved people, as well as
many runaways. The total number may have been about 10,000.[32] Owners of African slaves in England would advertise slave-sales and rewards for the recapture of runaways.
A number of freed slaves managed to achieve prominence in British society. Ignatius Sancho
(1729–1780), known as 'The Extraordinary Negro', opened his own
grocer's shop in Westminster. He was famous for his poetry and music,
and his friends included the novelist Laurence Sterne, David Garrick
the actor and the Duke and Duchess of Montague. He is best known for
his letters which were published after his death. Others such as Olaudah Equiano and Ottobah Cugoano were equally well known, and along with Ignatius Sancho were active in the abolition campaign.
Triangular trade
By the 18th century, the slave trade became a major economic mainstay for such cities as Bristol, Liverpool and Glasgow,
engaged in the so-called "Triangular trade". The ships set out from
Britain, loaded with trade goods which were exchanged on the West
African shores for slaves captured by local rulers from deeper inland;
the slaves were transported through the infamous "Middle Passage"
across the Atlantic, and were sold at considerable profit for labour in
plantations. The ships were loaded with export crops and commodities,
the products of slave labour, such as sugar and rum, and returned to Britain to sell the items.
The Isle of Man and the transatlantic slave trade
The Isle of Man
was involved in the transatlantic African slave trade. Goods from the
slave trade were bought and sold on the Isle of Man, and Manx merchants,
seamen, and ships were involved in the trade.
Judicial decisions
No legislation was ever passed in England that legalised slavery, unlike the Portuguese Ordenações Manuelinas (1481–1514), the Dutch East India Company Ordinances (1622), and France's Code Noir (1685), and this caused confusion when Englishmen brought home slaves they had legally purchased in the colonies. John Locke, the philosophical champion of the Glorious Revolution,
asserted that "every man has property in his own person" but allowed
for the enslavement of war captives --a popular defense of slavery
throughout the seventeenth, eighteenth, and nineteenth centuries in
England (§27, Ch.V=; II.iv.24). Locke also had stock in the Royal Africa Company. In Butts v. Penny
(1677) 2 Lev 201, 3 Keb 785, an action was brought to recover the value
of 10 slaves who had been held by the plaintiff in India. The court
held that an action for trover
would lie in English law, because the sale of non-Christians as slaves
was common in India. However, no judgment was delivered in the case.
An English court case of 1569 involving Cartwright who had bought a slave from Russia ruled that English law could not recognise slavery. This ruling was overshadowed by later developments, particularly in the Navigation Acts, but was upheld by the Lord Chief Justice in 1701 when he ruled that a slave became free as soon as he arrived in England.
Agitation saw a series of judgments repulse the tide of slavery. In Smith v. Gould (1705–07) 2 Salk 666, John Holt (Lord Chief Justice) stated that by "the common law no man can have a property in another". (See the "infidel rationale".)
In 1729 the Attorney General and Solicitor General of England signed the Yorke–Talbot slavery opinion,
expressing their view (and, by implication, that of the Government)
that slavery of Africans was lawful in England. At this time slaves were
openly bought and sold on commodities markets at London and Liverpool. Slavery was also accepted in Britain's many colonies.
Lord Henley LC said in Shanley v. Harvey (1763) 2 Eden 126, 127 that as "soon as a man sets foot on English ground he is free".
After R v. Knowles, ex parte Somersett
(1772) 20 State Tr 1 the law remained unsettled, although the decision
was a significant advance for, at the least, preventing the forceable
removal of anyone from England, whether or not a slave, against his
will. A man named James Somersett was the slave of a Boston customs
officer. They came to England, and Somersett escaped. Captain Knowles
captured him and took him on his boat, Jamaica bound. Three
abolitionists, saying they were his "godparents", applied for a writ of habeas corpus. One of Somersett's lawyers, Francis Hargrave, stated "In 1569, during the reign of Queen Elizabeth I,
a lawsuit was brought against a man for beating another man he had
bought as a slave overseas. The record states, 'That in the 11th [year]
of Elizabeth [1569], one Cartwright brought a slave from Russia and
would scourge him; for which he was questioned; and it was resolved,
that England was too pure an air for a slave to breathe in'." He argued
that the court had ruled in Cartwright's case that English common law
made no provision for slavery, and without a basis for its legality,
slavery would otherwise be unlawful as false imprisonment and/or
assault. In his judgment of 22 June 1772, Lord Chief Justice William Murray, Lord Mansfield, of the Court of King's Bench, started by talking about the capture and forcible detention of Somersett. He finished with:
So high an act of dominion must be recognized by the law of the country where it is used. The power of a master over his slave has been exceedingly different, in different countries.
The state of slavery is of such a nature, that it is incapable of being introduced on any reasons, moral or political, but only by positive law, which preserves its force long after the reasons, occasion, and time itself from whence it was created, is erased from memory.
It is so odious, that nothing can be suffered to support it, but positive law. Whatever inconveniences, therefore, may follow from the decision, I cannot say this case is allowed or approved by the law of England; and therefore the black must be discharged.
Several different reports of Mansfield's decision appeared. Most
disagree as to what was said. The decision was only given orally; no
formal written record of it was issued by the court. Abolitionists
widely circulated the view that it was declared that the condition of
slavery did not exist under English law,
although Mansfield later said that all that he decided was that a slave
could not be forcibly removed from England against his will.
After reading about Somersett's Case, Joseph Knight, an enslaved African who had been purchased by his master John Wedderburn in Jamaica and brought to Scotland, left him. Married and with a child, he filed a freedom suit, on the grounds that he could not be held as a slave in Great Britain. In the case of Knight v. Wedderburn (1778), Wedderburn said that Knight owed him "perpetual servitude". The Court of Sessions of Scotland ruled against him, saying that chattel slavery was not recognised under the law of Scotland,
and slaves could seek court protection to leave a master or avoid being
forcibly removed from Scotland to be returned to slavery in the
colonies.
Abolition
prevented them from becoming Members of Parliament.
William Wilberforce,
a member of the House of Commons as an independent, became the
Parliamentary spokesman for the abolition of the slave trade in Britain.
His conversion to Evangelical Christianity in 1784 played a key role in
interesting him in this social reform. William Wilberforce's Slave Trade Act 1807 abolished the slave trade in the British Empire. It was not until the Slavery Abolition Act 1833
that the institution finally was abolished, but on a gradual basis.
Since land owners in the British West Indies were losing their unpaid
labourers, they received compensation totaling £20 million.
The Royal Navy established the West Africa Squadron
(or Preventative Squadron) at substantial expense in 1808 after
Parliament passed the Slave Trade Act. The squadron's task was to
suppress the Atlantic slave trade
by patrolling the coast of West Africa, preventing the slave trade by
force of arms, including the interception of slave ships from Europe,
the United States, the Barbary pirates, West Africa and the Ottoman Empire.
The Church of England was implicated in slavery. Slaves were owned by the Anglican Church's Society for the Propagation of the Gospel in Foreign Parts (SPGFP), which had sugar plantations in the West Indies. When slaves were emancipated by Act of the British Parliament in 1834, the British government paid compensation to slave owners. Among those they paid were the Bishop of Exeter and three business colleagues, who received compensation for 665 slaves.
Modern evaluations of economic impact
Historians and economists have debated the economic effects of
slavery for Great Britain and the North American colonies. Many
analysts, such as Eric Williams, suggest that it allowed the formation
of capital that financed the Industrial Revolution,
although the evidence is inconclusive. Slave labour was integral to
early settlement of the colonies, which needed more people for labour
and other work. Also, slave labour produced the major consumer goods
that were the basis of world trade during the eighteenth and early
nineteenth centuries: coffee, cotton, rum, sugar, and tobacco. Slavery was far more important to the profitability of plantations
and the economy in the American South; and the slave trade and
associated businesses were important to both New York and New England.
In 2006, the then British Prime Minister, Tony Blair, expressed his deep sorrow over the slave trade, which he described as "profoundly shameful". Some campaigners had demanded reparations from the former slave trading nations.
In recent years, several institutions have begun to evaluate their own links with slavery. For instance, English Heritage produced a book on the extensive links between slavery and British country houses in 2013, Jesus College has a working group to examine the legacy of slavery within the college, and the Church of England, the Bank of England, Lloyd's of London and Greene King have all apologised for their historic links to slavery.
UCL has developed a database examining the commercial, cultural,
historical, imperial, physical and political legacies of slavery in
Britain (see 'external links').
