Debt bondage, also known as debt slavery, bonded labour, or peonage, is the pledge of a person's services as security for the repayment for a debt or other obligation, where the terms of the repayment are not clearly or reasonably stated, and the person who is holding the debt thus has some control over the laborer. Freedom is assumed on debt repayment. The services required to repay the debt may be undefined, and the services' duration may be undefined, thus allowing the person supposedly owed the debt to demand services indefinitely. Debt bondage can be passed on from generation to generation.

The Black Codes, sometimes called Black Laws, were laws governing the conduct of African Americans. In 1832, James Kent wrote that "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free colored persons of African blood; and in no part of the country do the latter, in point of fact, participate equally with the whites, in the exercise of civil and political rights." Although Black Codes existed before the Civil War and many Northern states had them, it was the Southern U.S. states that codified such laws in everyday practice. The best known of them were passed in 1865 and 1866 by Southern states, after the American Civil War, in order to restrict African Americans' freedom, and to compel them to work for low wages.

Child prostitution is prostitution involving a child, and it is a form of commercial sexual exploitation of children. The term normally refers to prostitution of a minor, or person under the legal age of consent. In most jurisdictions, child prostitution is illegal as part of general prohibition on prostitution.

A fazenda is a plantation found throughout Brazil; during the colonial period. They were concentrated primarily in the northeastern region, where (sugar) was produced, expanding during the 19th century in the southeastern region to coffee production. Fazenda now denotes any kind of farm in Brazilian Portuguese and occasionally in other Portuguese varieties as well.

A hacienda, in the colonies of the Spanish Empire, is an estate, similar to a Roman latifundium. Some haciendas were plantations, mines or factories. Many haciendas combined these activities. The word is derived from the Spanish verb "hacer" or its gerund "haciendo", from Latin "facer", meaning 'to make' and 'making' respectively, and were largely business enterprises consisting of various money-making ventures including raising farm animals and maintaining orchards.

Human trafficking is the trade of humans for the purpose of forced labour, sexual slavery, or commercial sexual exploitation for the trafficker or others. This may encompass providing a spouse in the context of forced marriage, or the extraction of organs or tissues, including for surrogacy and ova removal. Human trafficking can occur within a country or trans-nationally. Human trafficking is a crime against the person because of the violation of the victim's rights of movement through coercion and because of their commercial exploitation. Human trafficking is the trade in people, especially women and children, and does not necessarily involve the movement of the person from one place to another.

The trafficking of persons is the fastest growing and most profitable criminal activity after drug and arms trafficking. According to the United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, human trafficking is defined as follows: “Trafficking in persons shall mean the recruitment, transportation, transfer, harboring or receipt of persons, by means of the threat or use of force or other forms of coercion, of abduction, of fraud, of deception, of the abuse of power or of a position of vulnerability or of the giving or receiving of payments or benefits to achieve the consent of a person having control over another person, for the purpose of exploitation. Exploitation shall include, at a minimum, the exploitation of the prostitution of others or other forms of sexual exploitation, forced labor or services, slavery or practices similar to slavery, servitude or the removal of organs.”

Indentured servitude is a form of labor in which a person is contracted to work without salary for a specific number of years. The contract, called an "indenture", may be entered voluntarily for eventual compensation or debt repayment, or it may be imposed as a judicial punishment. Historically, it has been used to pay for apprenticeships, typically when an apprentice agreed to work for free for a master tradesman to learn a trade. Later it was also used as a way for a person to pay the cost of transportation to colonies in the Americas.

Indentured servitude in Pennsylvania (1682-1820s): The institution of indentured servitude has a significant place in the history of labor in Pennsylvania. From the founding of the colony (1681/2) to the early post-revolution period (1820s), indentured servants contributed considerably to the development of agriculture and various industries in Pennsylvania. Moreover, Pennsylvania itself has a notable place in the broader history of indentured servitude in North America. As Cheesman Herrick stated, "This system of labor was more important to Pennsylvania than it was to any other colony or state; it continued longer in Pennsylvania than elsewhere."

The Code de l'indigénat, called régime de l'indigénat or simply indigénat by modern French historians, were diverse and fluctuating sets of laws and regulations characterized by arbitrariness which created in practice an inferior legal status for natives of French colonies from 1881 until 1944–1947.

In historic Chilean agriculture an inquilino is a labourer indebted to a landlord who allows him to form a farm in parts of his property and who in exchange works without pay for the landlord. The inquilinos provided key manpower to carry out tasks like the gathering of livestock (rodeo) and slaughter. For inquilinos living in wheat-producing regions duties increased as the Chilean wheat cycle went on in from the 18th century onwards. The inquilinaje institution that characterized large parts of Chilean agriculture were eliminated by the Chilean land reform in the 1960s and early 1970s. Historian Mario Góngora has researched on the history of the inquilinos.

Involuntary servitude or involuntary slavery is a legal and constitutional term for a person laboring against that person's will to benefit another, under some form of coercion, to which it may constitute slavery. While laboring to benefit another occurs also in the condition of slavery, involuntary servitude does not necessarily connote the complete lack of freedom experienced in chattel slavery; involuntary servitude may also refer to other forms of unfree labor. Involuntary servitude is not dependent upon compensation or its amount.

Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States. Other areas in the United States were also affected by formal and informal policies of segregation, but many states outside the South had adopted laws, beginning in the late nineteenth century, that variously banned discrimination in public accommodations and voting. Southern laws were enacted in the late 19th and early 20th centuries by white Southern Democrat-dominated state legislatures to disenfranchise and remove political and economic gains made by black people during the Reconstruction period. Jim Crow laws were enforced until 1965.

A loan shark is a person who offers loans at extremely high interest rates, has strict terms of collection upon failure, and generally operates outside the law. Because loan sharks operating illegally cannot reasonably expect to be able to use the legal system to collect such debts, they often resort to enforcing repayment by blackmail and threats of violence. Historically, many moneylenders skirted between legal and criminal activity. In the recent western world, loan sharks have been a feature of the criminal underworld.

Panyarring was the practice of seizing and holding persons until the repayment of debt or resolution of a dispute which became a common activity along the Atlantic coast of Africa in the 18th and 19th centuries. The practice developed from pawnship, a common practice in West Africa where members of a family borrowing money would be pledged as collateral to the family providing credit until the repayment of the debt. Panyarring though is different from this practice as it involves the forced seizure of persons when a debt was not repaid.

Peon usually refers to a person subject to peonage: any form of wage labor in which a laborer (peon) has little control over employment conditions. Peon and peonage can refer to both the colonial period and post-colonial period of Latin America as well as the period after the end of slavery in the United States, when "Black Codes" were passed to retain African American freedmen as labor through other means.

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 developed during the Late Antiquity and Early Middle Ages in Europe and lasted in some countries until the mid-19th century.

Slavery in ancient Egypt existed since the Old Kingdom. Discussions of slavery in Pharaonic Egypt are complicated by terminology used by the Egyptians to refer to different classes of servitude over the course of dynastic history. Interpretation of the textual evidence of classes of slaves in ancient Egypt has been difficult to differentiate by word usage alone. There were three types of enslavement in Ancient Egypt: chattel slavery, bonded labor, and forced labor. But even these types of slavery are susceptible to individual interpretation based on evidence and research. Egypt's labor culture is represented by many men and women, and it is difficult to claim their social status into one category.
