This is a list of censors of the Roman Republic, consisting of all recorded office holders. This list, unless otherwise indicated, is taken from Thomas Robert Shannon Broughton, The Magistrates of the Roman Republic, Philological Monograph No. 15, vols. 1 and 2. (New York: American Philological Association, 1951, 1952).
Before 443 BC, the consuls were responsible for the census. In 443 BC, the right to take the census was moved from the consuls to the newly established office of censor. They were chosen exclusively from patricians.
In 393 BC, Marcus Cornelius Maluginensis was elected suffect censor to replace the deceased censor Gaius Iulius Iullus. In 351 BC, Gaius Marcius Rutilus was elected as the first plebeian censor. According to the Lex Publilia, since 339 BC at least one of the censors had to be plebeian. In 312 BC, Appius Claudius Caecus was elected censor without being consul before.
In 294 and 265 BC, Gaius Marcius Rutilus Censorinus was elected censor. This was the only time a person was elected censor twice. Marcius prevented this situation from repeating itself by originating a law stating that no one could be elected censor twice.
In 131 BC, for the first time both censors were plebeian.
After only one year in office the in 109 BC elected censor Marcus Livius Drusus died. His colleague Marcus Aemilius Scaurus at first refused to resign but resigned when new censors were elected in 108 BC.
Lucius Marcius Philippus and Marcus Perperna were elected censors in 86 BC. Due to civil war and the consequences of Sulla's dictatorship, no new censors were elected until 70 BC.
