Continued agitation to this effect resulted in an agreement in 452 B.C. between patricians and plebeians that decemvirs should be appointed to draw up a code, that during their tenure of office all other magistracies should be in abeyance, that they should not be subject to appeal, but that they should be bound to maintain the laws which guaranteed by religious sanctions the rights of the plebs. The first board of decemvirs (apparently consisting wholly of patricians) was appointed to hold office during 451 B.C.; and the chief man among them was Appius Claudius.

Livy (iii. 32) says that only patricians were eligible. Mommsen, however, held that plebeians were legally eligible, though none were actually appointed for 451. The decemvirs ruled with singular moderation, and submitted to the Comitia Centuriata a code of laws in ten headings, which was passed. So popular were the decemvirs that another board of ten was appointed for the following year, some of whom, if the extant list of names is correct, were certainly plebeians.
