Clean Slate Proclamations (Ancient Debt Jubilees)

Overview

Clean Slate proclamations were periodic royal decrees issued by rulers across Bronze Age Mesopotamia, from roughly 2400 to 1400 BC, that cancelled outstanding agrarian debts, freed people held in debt bondage, and restored land that had been forfeited to creditors back to its original smallholders.[1] Historians and economist Michael Hudson have identified around thirty such general debt cancellations across this period, known by different names in different city-states and periods — amargi in Lagash (Sumer), nig-sisa in Ur, andurarum in Ashur, and misharum in Babylon — with the Sumerian amargi literally meaning a "return to the mother [state]," i.e., a restoration of the original social order.[1][2][3]

Hudson's account, developed across decades of research culminating in his book …and forgive them their debts: Lending, Foreclosure and Redemption From Bronze Age Finance to the Jubilee Year (2018), sets out the three functions in his own words: "These proclamations had three functions: (1) They restored financial balance by annulling the backlog of crop debts that had accrued; (2) they liberated indebted bondservants (and their families)" — and, third, they restored land-tenure rights, so that debtors could keep living productively on the land, paying taxes, and remaining available for military service and corvée labor.[1] He argues these proclamations served a specific economic function: interest-bearing agrarian debt in these societies tended to compound faster than smallholders' capacity to repay it, so left unchecked it would have concentrated land in creditors' hands and reduced a growing share of the population to bondage, undermining the crown's tax base and its supply of free labor for corvée duty and military service.[1] Periodic clean slates reset this process before it went too far, restoring the mixed independent-smallholder economy the state relied on. Hudson connects this tradition to the Biblical Jubilee year (Leviticus 25) and presents it as the deep-historical precedent for treating unconstrained rent and debt claims on land as a recurring threat to social and fiscal stability, a theme he develops elsewhere in the more contemporary financial-rent argument of Killing the Host.[1]

Charpin, chair of Mesopotamian civilisation at the Collège de France, is the standard modern authority on the Old Babylonian mîšarum ("justice/equity") edicts and the andurārum ("release"); his work grounds the terminology and dating independently of Hudson's framing. See also his 2022 Collège de France lecture "Justice: the andurârum, back to the original situation," which glosses the andurârum as expressing "the will to return to what was believed to be the perfection of the origins" — an independent scholarly corroboration of the "return to the [original state]" sense the Sumerian amargi also carries. Collège de France (open access, audio + abstract). Note: some historians regard Hudson's account as overstating the generality and social intent of the practice, which is why the terminology here is now cross-checked against Charpin's specialist scholarship.
