Decemviri

The consuls for 445 BC -- Appius Claudius and M. Cornelius Maluginensis -- took the extraordinary step of adding eight members to their office: M. Sergius, L. Minucius, Q. Fabius Vibulanus, Q. Poetelius, T. Antonius Merenda, C. Duillius, S. Opius Cornicen, M. Rabuleius. These were known in Roman history as the decemviri (Latin for "ten men").

Livy likened them to ten Tarquins, who created many injustices and were a terror to the people. They were still in power at the ides of May at the end of their term. Lucius Valerius P.f. Potitus and Marcus Horatius Barbatus, on assuming the rank of consul in 443 BC banished the decemviri.
