Slavery is a legal economic system with involuntary servitude, such that the people held in bondage must work for their owner, and can be bought and sold (see slave trade).
Legally, the slave has limited rights. For example, it was a crime in the American South to kill or maim a slave, except in self-defense.
In the American South, slavery normally was a lifetime condition, and children born to slave mothers automatically became slaves of the owner.
In human history, slavery originated when people were captured in warfare. Secondarily, slavery resulted when some able-bodied people became so poor through debts that some wealthy people claimed them as property at least until they worked off their debts. The Year of Jubillee was instituted by God for His own nation in order to prevent slavery from becoming a means by which cleverly unscrupulous, or cleverly ignorant, people made a living, such as happened in the American South.
In America the vast majority of slaves were African blacks, and many of these had been bought from African tribal leaders; Indians starved themselves to death rather than live as slaves. From 1500 to 1820, hundreds of thousands of Europeans were captured in war by Muslims and made slaves.
Western Christendom abolished slavery during the 19th century. The last forms of legal slavery were outlawed in 1970 in the Arabian countries, but hidden slavery still exists today in remote parts of Africa such as the Sudan where Arabs own black slaves. In Mauritania, dark-skinned people own lighter-skinned slaves.
Slavery was found in the history of most civilizations. Slavery flourishes where there is a high demand for labor and not enough workers. When the workers are plentiful, slavery dies out because it is unprofitable. That is, it becomes cheaper to free a slave and hire low cost paid labor than to buy and maintain slaves. Typically, when it had almost died out, it was made illegal by the government, as in Brazil.
The most famous instance of slavery was in the American South until it was forcibly ended during the American Civil War (1861-65)--the only major war in world history fought over slavery.
The two main forms of slavery are house servants (in which slaves are luxury items owned by the rich), and field work, in which slaves are used as a cheap labor force. If free labor is cheaper than expensive slaves, slavery will disappear. If there is a shortage of laborers (and an abundance of work to do), slavery becomes economically possible. It is especially profitable in new lands with few people and rich soils or mines that require imported labor.
Slavery tended to die out in cities and flourished only in rural areas. In the cities rich families owned many slaves as a luxury good guaranteeing good servants. Otherwise, slaves in cities were more expensive to maintain than free labor, which could be hired and fired as needed. Slave labor was profitable for farms, mines, and construction jobs; it was not profitable for factories.
Most ancient civilizations, including Greece and Rome, had slavery on a large scale.
In Egypt, Hebrews were slaves. The primary slave market in ancient Greece was on an island in the Aegean sea known as "Delos." From there slaves were traded and used throughout the Greek city-states. In ancient Athens about 30% of the population consisted of slaves.
Often prisoners of wars in ancient history were used as slaves, particularly during the Roman Empire. Historians debate how extensive slavery was in the Roman Empire--estimates go as high as 25% of the population. Christianity helped lessen the harshness by which Romans treated slaves.
Slavery died out in the Roman Empire because the population was ample to work the land. Most of the slaves became serfs, who were attahed to certain lands but who had more legal rights and who could not be bought and sold or moved off their specific land.
Slavery was a major institution in Russia, and families facing starvation often sold themselves into slavery. Russian agricultural slaves were formally converted into serfs earlier in 1679. In 1723, when the Peter the Great converted the remaining household slaves into house serfs.  Serfdom was abolished in 1863 by Tsar Alexander II; however, most serfs had to pay the government for giving them land.
In 1455, a "papal bull" (formal letter by the pope) justified a right of Christian nations to enslave any non-Christian in the name of exploration. The Spanish had already been enslaving South American natives on a limited basis, but with the rise of sugar plantations the need for a larger slave force arose. 12 million of African slaves were brought by the Europeans to Mexico, Peru, the Caribbean and Brazil. The demand for sugar was exploding throughout the entire western world. Soon France, the Netherlands and Britain were also establishing profitable sugar plantations in the new world. The plantation system began in Brazil, where rich white plantation owners were the highest rung in the social hierarchy and black slaves were at the bottom. Obviously life on a sugar plantation was very hard work for a slave; most died in less than 10 years, and had to be replaced.
African Slave Trade
Slavery was widespread within Africa itself, and the richest in Africa were not those owning the most land, but those who owned the most slaves. In the Sahara Desert, slaves worked in caravans and were used in gold and salt mining. Slaves were usually prisoners of war from other areas of Africa, or debtors, or enemies or the king, but many women outside of those three categories were also enslaved in African societies.
European traders encouraged Africans to trade slaves with them. The Trans-Atlantic slave trade became a booming business for Europeans and Africans alike, in which African rulers sold prisoners of war and even their people to Europeans for goods such as iron, alcohol, tobacco and most importantly, guns. Trans-Atlantic trade led to the degrading use of "chattel" slaves, whereby the slaves were treated purely as property of the owner. The slaves served as sailors, skilled craftsmen or farmers. The journey across the Atlantic, known as the Middle Passage, led to the death of 10-20% of the African slaves. But an even higher percentage lost their lives in the journey from their homes in Africa to the African coast, where they were to board the slave ships.
- After kidnapping potential slaves, merchants forced them to walk in slave caravans to the European coastal forts, sometimes as far as 1,000 miles. Shackled and underfed, only half the people survived these death marches. 
The Trans-Atlantic slave trade was one component in a system of routes known as the "Triangular Trade" between South America, New England, and the West Coast of Africa. The three main items that were exchanged were sugar, rum and slaves. European goods, mainly guns, were used to buy slaves from Africa. The slaves were then shipped to the Americas. Then, from America, sugar, rum and tobacco were brought back to Europe, completing the "triangle" of trade. Slavery is one of the less noble aspects of American history.
Between 1530 and 1780, Europeans including Britons and even some Americans were frequently taken captive and enslaved by privateers from the Barbary States. Estimates of so-called "white slavery" vary from as little as 50,000 to in the millions . Generally Europeans enslaved by the corsairs were usually poorer sea merchants and city dwellers whose families were unable to pay the ransom necessary to free them. Often the Pasha would purchase the female captives into his harem. Many were forced to "go turk" or convert to "mohammadism" in order to stay with their children who were raised as Muslims. Occasionally slaves would convert in order to escape harsher labors such as tending the oars in the corsairs .
For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East. Kefe was one of the best known and significant trading ports and slave markets. In a process called "harvesting of the steppe" Crimean Tatars enslaved many Slavic peasants.
In Senegambia, between 1300 and 1900, close to one-third of the population was enslaved. In early Islamic states of the western Sudan, including Ghana (750-1076), Mali (1235–1645), Segou (1712–1861), and Songhai (1275-1591), about a third of the population were slaves. In Sierra Leone in the 19th century about half of the population consisted of slaves. In the 19th century at least half the population was enslaved among the Duala of the Cameroon, the Igbo and other peoples of the lower Niger, the Kongo, and the Kasanje kingdom and Choke of Angola. Among the Ashanti and Yoruba a third of the population consisted of slaves. The population of the Kanem was about a third-slave. It was perhaps 40% in Bornu (1396–1893). Between 1750 and 1900 from one- to two-thirds of the entire population of the Fulani jihad states consisted of slaves. The population of the Sokoto caliphate formed by Hausas in the northern Nigeria and Cameroon was half-slave in the 19th century. It is estimated that up to 90% of the population of Arab-Swahili Zanzibar was enslaved. Roughly half the population of Madagascar was enslaved.
The Anti-Slavery Society estimated that there were 2 million slaves in Ethiopia in the early 1930s, out of an estimated population of between 8 and 16 million. Ethiopia officially abolished slavery and serfdom after regaining its independence in 1942. On August 26, 1942 Haile Selassie issued a proclamation outlawing slavery.
India in 1841 had an estimated 8,000,000 or 9,000,000 slaves in India. In Malabar, about 15% of the population were slaves. Slavery was abolished in both Hindu and Muslim India by the Indian Slavery Act V. of 1843. Provisions of the Indian Penal Code of 1861 effectively abolished slavery in India by making the enslavement of human beings a criminal offense.
Indigenous slaves existed in Korea. During the Joseon Dynasty (1392–1910) about 30% to 40% of the Korean population consisted of slaves. Slavery was hereditary, as well as a form of legal punishment. There was a slave class with both government and privately owned slaves, and the government occasionally gave slaves to citizens of higher rank. Privately owned slaves could be inherited as personal property. During poor harvests and famine, many peasants would voluntarily become slaves in order to survive. In the case of private slaves they could buy their freedom. Slavery was officially abolished with the Gabo Reform of 1894.
Slavery was also known among Arabs into the 20th century. As recently as the 1950s, Saudi Arabia had an estimated 450,000 slaves, 20% of the population. It is estimated that as many as 200,000 people had been taken into slavery in Sudan during the Second Sudanese Civil War. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was finally criminalized in 2007. In Niger, slavery is also a current phenomenon; a Nigerien study has found that more than 800,000 people, or almost 8% of the population, are slaves. The Tuareg-rebels in Mali have a long tradition of practicing slavery.
Also, the term "slavery" is often used metaphorically for sex workers who are controlled by pimps.

Abolition of Slavery
France had slavery in its Caribbean colonies and Condorcet (1743 - 1794), an influential philosophe, rejected slavery as antithetical to Enlightenment morality. He became a leader in the antislavery movement and in the 1780s attacked the institution of slavery on philosophical and moral grounds in his writings. After 1780, Condorcet took a leading, though secret, role in antislavery agitation by writing Reflections on Negro Slavery under the pseudonym Dr. Schwartz. In 1784, he was a founder and principal actor in La Société des Amis des Noirs, which sought to prepare for the eventual abolition of slavery. By 1794, Condorcet still supported colonization, but believed that a colonization based on liberal economics and civil equality could transform the world.
Napoleon (ruled 1799-1815) made a major adventure into the Caribbean--sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under black leader Toussaint L'Ouverture who had revolted and killed off the whites and mulattoes. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore reestablished slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their comrades who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of reestablishing slavery - which explicitly contradicted the ideals of the French Revolution - demoralized the French troops. The demoralized French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic.  Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off Louisiana to the U.S.
The first black slaves were brought to Jamestown Colony early on. Originally, slavery was legal in every British American colony. However, after the American Revolution, the Massachusetts Supreme Court ruled that, since the new state constitution read, "All men are born free and equal, and have certain natural, essential, and unalienable rights; among which may be reckoned the right of enjoying and defending their lives and liberties", it made slavery illegal. By 1804, slavery had been abolished in every northern state.
The South after 1800 became more militant in defense of slavery. John C. Calhoun and other southerners called it the South's "peculiar institution" and proclaimed it a good idea. Some proponents suggested it would also be a good idea for white workers who were living under worse conditions in Northern cities. It flourished in the Southern states until Abraham Lincoln and his Union Army abolished it during the American Civil War. This was a case of racial slavery--the slaves were black, the owners were white.
Emancipation of slaves in the British Caribbean became a major cause by the 1800s, when abolitionists such as William Wilberforce and John Wesley began speaking out against the evils of the system. Wilberforce was supported in his efforts by John Newton, a slave trader who became a Christian and then opposed the slave trade. In 1807 the House of Commons passed the Slave Trade Abolition Bill by a 283-16 vote. It made the international slave trade a crime of piracy and sent the Royal Navy to enforce it. In 1808 the U.S. also outlawed the international trade. However, some slave traders evaded the prohibition--many were caught and hung, with the freed captives sent to Sierra Leone. Slavery remained legal inside the British Empire (including Canada) until 1833 when the government bought all the slaves from the owners and freed them. 
In the United States, the northern states abolished slavery by 1803--most of the slaves there were house servants. In The South, however, cotton made slavery very profitable and 11 states seceded in 1861 to protect their interest. Abraham Lincoln achieved the end of slavery in 1863-65, using the Army and the 13th Amendment. In Cuba and Brazil, slavery was unprofitable and finally collapsed in the 1880s as few people wanted to buy slaves.
- Harriet Tubman, Underground Railroad. (1820 - 1913)  Well-known associate of the Underground Railroad. Acted as a spy and led raids to assist others in gaining their freedom.
- Frederick Douglass, orator, writer and publisher. (1817 - 1875)  Respected leader of the abolitionist movement, consummate freedom seeker, orator and publisher.
- Ralph Waldo Emerson, unitarian minister and freethinker. (1803-1882)  Expressed visceral public disapproval of the Fugitive Slave Act of 1850. Exhorted people to "do the duty of the hour", and support abolition.
- William Lloyd Garrison, anti-slavery editor of the Liberator (1805 - 1879); the single most imfluential abolitionist  Founded the Liberator with partner Isaac Knapp in 1831.
- Elizur Wright, abolitionist, freethinker. (1804-1885)  Became involved in the abolitionist movement while attending Yale university. Eventually worked as a secretary with the American Anti-Slavery Society in 1833 and assumed the editorship of the Massachusetts Abolitionist in 1839.
- John Brown (1800-1859), tried to lead a slave rebellion in 1859; the slaves did not join him, but white Southerners became convinced there were many more John Browns to come if they stayed in the Union
- John Stuart Mill, philosopher, essayist. (1806 - 1879)  Wrote numerous essays on abolition during the American Civil War. Asserted the war was being fought to abolish slavery, an unpopular political opinion at the time.
For a more detailed treatment, see Slavery in the Bible.
Slavery was an well-established institution throughout the Ancient Near East, and the Old Testament sanctions its form of regulated slavery, though that is seen as being counter cultural in its degree of amelioration, including as compared to that of ancient slave states as Greece and Rome, and the typical practice of slavery in American history. The New Testament does not condemn the institution itself, but makes requirements upon both masters and slaves in further improving treatment in the inherited economic institution.
Slave owners in the antebellum South cited both Old Testament and New Testament texts, such as Ephesians 6:5, “slaves, obey your masters”, in arguments for the Christian endorsement of slavery. Another Bible verse states that thieves should be sold into slavery. Under the Mosaic Law, Hebrew slaves could be kept for six years, and offered release in the seventh for nothing. They were to be treated as hired servants, and generous provisions given to them at termination, though they could choose to be lifetime servants. However, daughters who were sold to be betrothed to the owner or his son, were not set free in their seventh year but were to be allowed to be redeemed if that marriage had not taken place done. If marriage occurred, they were to be set free if the husband was negligent in his basic marital obligations.(Exodus 21:1-11; cf. Dt. 15:12-18)
The system of slavery commonly diminished a person to the point where they would be regarded as a thing or an object to be owned. The Christian abolitionists disagreed with this valuation, and saw the New Testament in particular, and its ethos of love for neighbor as oneself, as supporting the abolition of slavery, and advanced an interpretation of the Bible which presented human value in terms of God's parental love for all people as His children (see human rights).
While requiring Christian obedience  of slaves toward their masters, the New Testament also requires masters to exercise their duties in the fear of God, and prohibits threatening, abuse or unequal pay for slaves. ((Eph. 6:9; Col. 4:1) (1Cor. 7:21) It also commands slaves to obtain freedom if possible, and contains the record of the apostle Paul requiring that the escaped slave Onesimus be received back by his master Philemon, no longer "as a servant, but above a servant, a brother beloved", even as Paul himself (Philemon 1:16,17)
Pat Robertson, while acknowledging the Old Testament's teachings on slavery, argues that "we have moved in our conception of the value of human beings over the years" until we have realized that slavery is "terribly wrong."
Curse of Ham
Some Southern white theologians before the Civil War asserted that the slavery of blacks was the result the curse of Ham. However, there is no evidence that the curse had to do with skin color, and the descendants of Canaan most likely were not black, and it is generally concluded that they did not settle in Africa.
