Slave in the context of "Manumission"

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. It developed during late antiquity and the Early Middle Ages in Europe and lasted in some countries until the mid-19th century.

Unlike slaves, serfs could not be bought, sold, or traded individually, though they could, depending on the area, be sold together with land. Actual slaves, such as the kholops in Russia, could, by contrast, be traded like regular slaves, abused with no rights over their own bodies, could not leave the land they were bound to, and marry only with their lord's permission.

A thrall was a slave or serf in Scandinavian lands during the Viking Age. The status of slave (þræll, þēow) contrasts with that of the freeman (karl, ceorl) and the nobleman (jarl, eorl).

Jizya (Arabic: جِزْيَة, romanized: jizya), or jizyah, is a type of taxation levied on non-Muslim subjects of a state governed by Islamic law. The Quran and hadiths mention jizya without specifying its rate or amount, and the application of jizya varied in the course of Islamic history. However, scholars largely agree that early Muslim rulers adapted some of the existing systems of taxation and modified them according to Islamic religious law.

Historically, the jizya tax has been understood in Islam as a fee for protection provided by the Muslim ruler to non-Muslims, for the exemption from military service for non-Muslims, for the permission to practice a non-Muslim faith with some communal autonomy in a Muslim state, and as material proof of the non-Muslims' allegiance to the Muslim state and its laws. The majority of Muslim jurists required adult, free, sane males among the dhimma community to pay the jizya, while exempting women, children, elders, handicapped, the ill, the insane, monks, hermits, slaves, and musta'mins—non-Muslim foreigners who only temporarily reside in Muslim lands. However, some jurists, such as Ibn Hazm, required that anyone who had reached puberty pay jizya. Islamic Regimes allowed dhimmis to serve in Muslim armies. Those who chose to join military service were also exempted from payment; some Muslim scholars claim that some Islamic rulers exempted those who could not afford to pay from the Jizya.

Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. Coca leaves contain cocaine which acts as a mild stimulant when chewed or consumed as tea, with slower absorption than purified cocaine and no evidence of addiction or withdrawal symptoms from natural use.

The coca plant is a shrub-like bush with curved branches, oval leaves featuring distinct curved lines, small yellowish-white flowers that develop into red berries. Genomic analysis reveals that coca, a culturally and economically important plant, was domesticated two or three separate times from the wild species Erythroxylum gracilipes by different South American groups during the Holocene. Chewing coca in South America began at least 8,000 years ago, as evidenced by coca leaves and calcite found in house floors in Peru's Nanchoc Valley, suggesting early communal use alongside the rise of farming. Coca use was subject to widespread use under Inca rule. The Incas deeply integrated coca into their society for labor, religion, and trade, valuing it so highly that they colonized new lands to cultivate it. Despite later Spanish attempts to suppress its use, even they relied on it to sustain enslaved laborers. Coca leaves have been traditionally used across Andean cultures for medicinal, nutritional, religious, and social purposes—serving as a stimulant, remedy for ailments, spiritual tool, and source of sustenance—especially through chewing and tea.

A slave market is a place where slaves are bought and sold. These markets are a key phenomenon in the history of slavery.

The sack of Rome in 455 was carried out by the Vandals led by their king Gaiseric.

A 442 treaty between the Western Roman Empire and Vandal Kingdom included a marriage of state between the daughter of Roman Emperor Valentinian III and the son of Gaiseric. Valentinian's successor Petronius Maximus violated the treaty by marrying his son to Valentinian's daughter, and Gaiseric retaliated with an invasion of Italy. Maximus did not organise a defence of Rome and was lynched by a Roman mob while trying to escape the city. Pope Leo I convinced Gaiseric to avoid the use of violence against residents of the city. The Vandals looted Rome for two weeks, causing widespread destruction to the city, stripping it of most of its valuables, and taking some residents as slaves. Maximus' successor Avitus had little support which led to the outbreak of the Roman civil war of 456.

In tsarist Russia, the term serf (Russian: крепостной крестьянин, romanized: krepostnoy krest'yanin, lit. 'bonded peasant') meant an unfree peasant who, unlike a slave, originally could be sold only together with the land to which they were "attached". However, this had stopped being a requirement by the 19th century, and serfs were by then practically indistinguishable from slaves. Contemporary legal documents, such as Russkaya Pravda (12th century onwards), distinguished several degrees of feudal dependency of peasants. While another form of slavery in Russia, kholopstvo, was ended by Peter I in 1723, serfdom (Russian: крепостное право, romanized: krepostnoye pravo) was abolished only by Alexander II's emancipation reform of 1861; nevertheless, in times past, the state allowed peasants to sue for release from serfdom under certain conditions, and also took measures against abuses of landlord power.

Serfdom became the dominant form of relation between Russian peasants and nobility in the 17th century. Serfdom most commonly existed in the central and southern areas of the Tsardom of Russia and, from 1721, of the subsequent Russian Empire. Serfdom was rare in Little Russia (parts of today's central Ukraine), other Cossack lands, the Urals and Siberia until the reign of Catherine the Great (r. 1762–1796), when it spread to Ukraine; noblemen began to send their serfs into Cossack lands in an attempt to harvest their extensive untapped natural resources.
