Concept
The abolition of slavery occurred at different times in different countries. It frequently occurred sequentially in more than one stage – for example, as abolition of the trade in slaves in a specific country, and then as abolition of slavery throughout empires. Each step was usually the result of a separate law or action. This timeline shows abolition laws or actions listed chronologically. It also covers the abolition of serfdom. Although slavery is technically illegal in all countries today, the practice continues in many locations around the world, primarily in Africa, Asia, and Eastern Europe, often with government support. Slavery in antiquity During classical antiquity, several prominent societies in Europe and the ancient Near East regulated enslavement for debt and the related but distinct practice of debt bondage (in which a creditor could extract compulsory labor from a debtor in repayment of their debt, but the debtor was not formally enslaved and was not subject to all the conditions of chattel slavery, such as being perpetually owned, sellable on the open market, or stripped of kinship). Reforms listed below such as the laws of Solon in Athens, the Lex Poetelia Papiria in Republican Rome, or rules set forth in the Hebrew Bible in the Book of Deuteronomy generally regulated the supply of slaves and debt-servants by forbidding or regulating the bondage of certain privileged groups (thus, the Roman reforms protected Roman citizens, the Athenian reforms protected Athenian citizens, and the rules in Deuteronomy guaranteed freedom to a Hebrew after a fixed duration of servitude), but none abolished slavery, and even what protections were instituted did not apply to foreigners or noncitizen subjects. Slavery in medieval Europe N.B.: Many of the listed reforms were reversed over succeeding centuries.
