. Slavery typically involves slaves being made to perform some form of work while also having their location or residence dictated by the enslaver. Many historical cases of enslavement occurred as a result of breaking the law, becoming indebted, or suffering a military defeat; other forms of slavery were instituted along demographic lines such as race. Slaves may be kept in bondage for life or for a fixed period of time, after which they would be granted freedom. Although slavery is usually involuntary and involves coercion, there are also cases where people voluntarily enter into slavery to pay a debt or earn money due to

Chattel slavery

As a social institution, chattel slavery classes slaves as ''chattels'' (

movements saw slavery as a violation of the slaves' rights as people (" all men are created equal"), and sought to abolish it. Abolitionism encountered extreme resistance but was eventually successful; the last Western country to abolish slavery, Brazil, did so in 1888. The last third-world country to abolish slavery, Mauritania, did not do so until 1981.


Bonded labour

Indenture, also known as bonded labour or debt bondage, is a form of unfree labour in which a person works to pay off a debt by pledging himself or herself as collateral. The services required to repay the debt, and their duration, may be undefined. Debt bondage can be passed on from generation to generation, with children required to pay off their progenitors' debt. It is the most widespread form of slavery today. Debt bondage is most prevalent in South Asia.

Forced labour

Forced labour, or unfree labour, is sometimes used to describe an individual who is forced to work against their own will, under threat of violence or other punishment, but the generic term "unfree labour" is also used to describe chattel slavery, as well as any other situation in which a person is obliged to work against their own will, and a person's ability to work productively is under the complete control of another person. This may also include institutions not commonly classified as slavery, such as

Other uses of the term

The word ''slavery'' is often used as a pejorative to describe any activity in which one is coerced into performing. Some argue that military drafts and other forms of coerced government labour constitute "state-operated slavery." Some libertarians and anarcho-capitalists view government taxation as a form of slavery. "Slavery" has been used by some

Characteristics


Private versus state-owned slaves

Slaves have been owned privately by individuals but have also been under state ownership. For example, the
kisaeng Kisaeng (Hangul: 기생, Hanja: 妓生, RR: ''Gisaeng''), also called ginyeo (Hangul: 기녀, Hanja: 妓女), were women from outcast or slave families who were trained to be courtesans, providing artistic entertainment and conversation to men ...

"Tribute labor" is compulsory labor for the state and has been used in various iterations such as

Economics

Economists have modeled the circumstances under which slavery (and variants such as
serfdom Serfdom was the status of many peasants under feudalism, specifically relating to manorialism, and similar systems. It was a condition of debt bondage and indentured servitude with similarities to and differences from slavery, which develo ...
) appear and disappear. One observation is that slavery becomes more desirable for
landowners In common law systems, land tenure, from the French verb "tenir" means "to hold", is the legal regime in which land owned by an individual is possessed by someone else who is said to "hold" the land, based on an agreement between both individual ...
where land is abundant but labour is scarce, such that rent is depressed and paid workers can demand high wages. If the opposite holds true, then it is more costly for landowners to guard the slaves than to employ paid workers who can demand only low wages because of the degree of competition. Thus, first slavery and then serfdom gradually decreased in Europe as the population grew. They were reintroduced in the Americas and in Russia as large areas of land with few inhabitants became available. Slavery is more common when the tasks are relatively simple and thus easy to supervise, such as large-scale monocrops such as sugarcane and

in the United States, to become prominent on large plantations where field hands toiled with factory-like precision. Then, each work gang was based on an internal division of labour that assigned every member of the gang to a task and made each worker's performance dependent on the actions of the others. The slaves chopped out the weeds that surrounded the cotton plants as well as excess sprouts. Plow gangs followed behind, stirring the soil near the plants and tossing it back around the plants. Thus, the gang system worked like an

. Since the 18th century, critics have argued that slavery retards technological advancement because the focus is on increasing the number of slaves doing simple tasks rather than upgrading their efficiency. For example, it is sometimes argued that, because of this narrow focus, technology in Greece – and later in Rome – was not applied to ease physical labour or improve manufacturing. Scottish economist Adam Smith stated that free labour was economically better than slave labour, and that it was nearly impossible to end slavery in a free, democratic, or republican form of government since many of its legislators or political figures were slave owners, and would not punish themselves. He further stated that slaves would be better able to gain their freedom under centralized government, or a central authority like a king or church. Similar arguments appeared later in the works of

, the profits generated worldwide by all forms of slavery in 2007 were $91.2 billion. That was second only to drug trafficking, in terms of global criminal enterprises. At the time the weighted average global sales price of a slave was estimated to be approximately $340, with a high of $1,895 for the average trafficked sex slave, and a low of $40 to $50 for debt bondage slaves in part of Asia and Africa. The weighted average annual profits generated by a slave in 2007 was $3,175, with a low of an average $950 for bonded labour and $29,210 for a trafficked sex slave. Approximately 40% of slave profits each year were generated by trafficked sex slaves, representing slightly more than 4% of the world's 29 million slaves.


Identification

Throughout history, slaves were clothed in a distinctive fashion, particularly with respect to the frequent lack of footwear, as they were rather commonly forced to go

slave code stated that "Slaves must go barefoot and must carry passes." It also puts slaves at a physical disadvantage because of the lack of protection against environmental conditions and in confrontations, thereby making it more difficult to escape or to rebel against their owners. This was the case in the majority of states. Most images from the respective historical period suggest that slaves were barefoot. Brother Riemer stated, " he slavesare, even in their most beautiful suit, obliged to go barefoot. Slaves were forbidden to wear shoes. This was a prime mark of distinction between the free and the bonded and no exceptions were permitted." According to the Bible, shoes have been considered badges of freedom since antiquity: "But the father said to his servants, Bring forth the best robe, and put ton him; and put a ring on his hand, and shoes on isfeet" (). This aspect can be viewed as an informal law in areas where slavery existed as any person sighted barefoot in public was assumed to be a slave. In certain societies this rule continues. The

Legal rights

Depending upon the era and the country, slaves sometimes had a limited set of legal rights. For example, in the
Province of New York The Province of New York (1664–1776) was a British proprietary colony and later royal colony on the northeast coast of North America. As one of the Middle Colonies, New York achieved independence and worked with the others to found the ...
, people who deliberately killed slaves were punishable under a 1686 statute. And, as already mentioned, certain legal rights attached to the nobi in Korea, to slaves in various African societies, and to black female slaves in the French colony of Louisiana. Giving slaves legal rights has sometimes been a matter of morality, but also sometimes a matter of self-interest. For example, in
ancient Athens Athens is one of the oldest named cities in the world, having been continuously inhabited for perhaps 5,000 years. Situated in southern Europe, Athens became the leading city of Ancient Greece in the first millennium BC, and its cultural achieve ...

outside of Italy. Generally, slaves in Italy were indigenous Italians. Foreigners (including both slaves and freedmen) born outside of Italy were estimated to have peaked at 5% of the total in the capital, where their number was largest. Those from outside of Europe were predominantly of Greek descent. Jewish slaves never fully assimilated into Roman society, remaining an identifiable minority. These slaves (especially the foreigners) had higher death rates and lower birth rates than natives and were sometimes subjected to mass expulsions. The average recorded age at death for the slaves in Rome was seventeen and a half years (17.2 for males; 17.9 for females).
