… “Faced with the potential for complete social breakdown, Sumerian and later Babylonian kings periodically announced general amnesties: “clean slates,” as economic historian Michael Hudson refers to them. Such decrees would typically declare all outstanding consumer debt null and void (commercial debts were not affected), return all land to its original owners, and allow all debt-peons to return to their families. Before long, it became more or less a regular habit for kings to make such a declaration on first assuming power, and many were forced to repeat it periodically over the course of their reigns. In Sumeria, these were called “declarations of freedom”—and it is significant that the Sumerian word amargi, the first recorded word for “freedom” in any known human language, literally means “return to mother”—since this is what freed debt-peons were finally allowed to do.”
