In Mesopotamia a farmer often pledged his wife, children or himself as security for a loan. After a bad harvest the creditor took them as workers until the debt was paid, and some were sold. Rulers periodically declared 'clean slates' that cancelled debts and freed pledges, from Enmetena of Lagash about 2400 BC to Babylonian kings. Biblical law prescribed releases too; Athens abolished debt slavery in 594 BC, and Rome restricted it in 326 BC.
Impact on society and the economy
It was early credit's dark side: lenders gained labor and land, small farmers lost their freedom. Outlawed by a 1956 UN convention, it still persists, for example in some South Asian brick kilns.
Think of it like
A loan secured not by property but by the borrower's own labor and family.
How we know
Loan contracts naming pledged family members, royal debt-cancellation edicts such as Ammi-saduqa's (about 1646 BC), Hammurabi's laws, the Hebrew Bible, and Greek and Roman histories.
Still debated
How common it was is unclear: surviving records show individual cases and royal edicts, not totals. Its scale today is also hard to measure.

▸Mesopotamian merchants, loans and interest could end in Debt bondage and slavery in ancient economiesWell documented
The connection
When harvests failed, farmers who had borrowed barley or silver could not repay. Because loans were often secured by family members or the borrower himself, default meant handing over a wife, children or one's own labor to the creditor, sometimes permanently.
When and how
Sumer and Babylonia, from about 2400 BC, among farming households and their temple, palace or private creditors.
How we know
Loan contracts name pledged persons, and royal edicts cancelling debts explicitly free those held for debt.
Debates
How often defaults ended in bondage, rather than renegotiation or rescheduling, cannot be measured from surviving records.
▸Code of Hammurabi's rules on loans and trade limited the term of Debt bondage and slavery in ancient economiesWell documented
The connection
Hammurabi's law 117 said a wife, son or daughter handed over for a debt must be freed in the fourth year, after three years of work. It did not abolish debt bondage, but it turned potential lifelong servitude into a fixed term.
When and how
Babylon, about 1754 BC. Hammurabi and other Babylonian kings also issued one-off debt-cancellation edicts.
How we know
The text of law 117 survives on the stele in the Louvre and in clay copies.
Debates
Whether the three-year limit was observed in practice is unknown. A similar fixed term, six years, appears later in biblical law (Exodus 21).
▸Debt bondage and slavery in ancient economies was ended for Athenian citizens by Solon's cancellation of debts in AthensMostly agreed
The connection
By about 600 BC debt had pushed many poor Athenians into bondage or sale abroad, and the city neared civil war. Solon's reform freed those held for debt and banned loans secured on a person, ending debt slavery for Athenian citizens permanently.
When and how
Athens, 594 BC (the traditional date), by Solon as chief magistrate (archon).
How sure are we?
Solon's surviving poems boast of freeing the enslaved and bringing sold Athenians home; Aristotle and Plutarch confirm the ban.
Debates
It protected citizens only; slavery of foreigners continued. How the 'sixth-parters' fit into the debt system is still debated.
