The Twelve Tables outlined early Roman law across various topics including procedures for courts and trials in Table I, inheritance laws in Table V, land rights in Table VII, laws around injury in Table VIII, public and sacred law in Tables IX-X, with a supplemental section in Table XI addressing distinctions between treatment of the rich and poor. The 12 Tables established core legal foundations for early Roman society across subjects like debt, family rights, guardianship, property ownership, and criminal matters.
