Featured within the Twelve Tables are five rules about how to execute judgments, in terms of debtors and creditors. These rules show how the ancient Romans maintained peace with financial policy. In his article "Development of the Roman Law of Debt Security," Donald E. Phillipson states the Twelve Tables were, “A set of statutes known as the Twelve Tables that was passed by an early assembly served as the foundation of the Roman private law. The Twelve Tables were enacted in the mid-fifth century B.C. as the result of a conflict among social classes in ancient Rome.” (pp. 1231–1232).
