Roman censor in the context of "Gaius Junius Bubulcus Brutus"

Marcus Porcius Cato (/ˈkɑːtoʊ/, KAH-toe; 234–149 BC), also known as Cato the Censor (Latin: Censorius), the Elder and the Wise, was a Roman soldier, senator, and historian known for his conservatism and opposition to Hellenization. He was the first to write history in Latin with his Origines, a now fragmentary work on the history of Rome. His work De agri cultura, a treatise on agriculture, rituals, and recipes, is the oldest extant prose written in the Latin language. His epithet "Elder" distinguishes him from his great-grandson Senator Cato the Younger, who opposed Julius Caesar.

He came from an ancient plebeian family who were noted for their military service. Like his forefathers, Cato was devoted to agriculture when not serving in the army. Having attracted the attention of Lucius Valerius Flaccus, he was brought to Rome. He was successively military tribune (214 BC), quaestor (204), aedile (199), praetor (198), consul (195) together with Flaccus, and censor (184). As praetor, he expelled usurers from Sardinia. As censor, he tried to save Rome's ancestral customs and combat Hellenistic influences.

The consuls were the two highest elected public officials of the Roman Republic (c. 509 BC to 27 BC). Romans considered the consulship the second-highest level of the cursus honorum—an ascending sequence of public offices to which politicians aspired—after that of the censor, which was reserved for former consuls. Each year, the centuriate assembly elected two consuls to serve jointly for a one-year term. The consuls alternated each month holding fasces (taking turns leading) when both were in Rome. A consul's imperium (military power) extended over Rome and all its provinces.

Having two consuls created a check on the power of any one individual, in accordance with the republican belief that the powers of the former kings of Rome should be spread out into multiple offices. To that end, each consul could veto the actions of the other consul.

Lucius Cassius Longinus Ravilla was a Roman politician. He served as consul in 127 BC and censor at the following lustrum in 125 BC.

His first recorded office was that of tribune of the plebs in 137 BC. As a tribune of the plebs, he successfully proposed in the concilium plebis a law to introduce secret ballot for all trials before the Assemblies except those related to perduellio (treason); the bill was supported by Scipio Aemilianus but opposed by the then-consul Marcus Aemilius Lepidus Porcina and his tribunician colleague Marcus Antius Briso.

Domitian (/dəˈmɪʃən, -iən/ də-MISH-ən, -⁠ee-ən; Latin: Domitianus; 24 October 51 – 18 September 96) was Roman emperor from 81 to 96. The son of Vespasian and the younger brother of Titus, his two predecessors on the throne, he was the last member of the Flavian dynasty. Described as "a ruthless but efficient autocrat", his authoritarian style of ruling put him at sharp odds with the Senate, whose powers he drastically curtailed.

Domitian had a minor and largely ceremonial role during the reigns of his father and brother. After the death of his brother, Domitian was declared emperor by the Praetorian Guard. His 15-year reign was the longest since Tiberius. As emperor, Domitian strengthened the economy by revaluing the Roman coinage, expanded the border defenses of the empire, and initiated a massive building program to restore the damaged city of Rome. Significant wars were fought in Britain, where his general Agricola made significant gains in his attempt to conquer Caledonia (Scotland), and in Dacia (Modern-day Romania), where Domitian was unable to achieve a decisive victory against King Decebalus. Domitian's government exhibited strong authoritarian characteristics. Religious, military, and cultural propaganda fostered a cult of personality, and by nominating himself as perpetual censor, he sought to control public and private morals.

Quintus Caecilius Metellus Macedonicus (c. 188 BC – 116 BC/115 BC) was a statesman and general of the Roman Republic during the second century BC. He was praetor in 148 BC, consul in 143 BC, the Proconsul of Hispania Citerior in 142 BC and censor in 131 BC. He got his agnomen, Macedonicus, for his victory over the Macedonians in the Fourth Macedonian War.

Lucius Valerius Flaccus (died 180 BC) was a Roman politician and general. He was consul in 195 BC and censor in 183 BC, serving both times with his friend Cato the Elder, whom he brought to the notice of the Roman political elite.

The Senate was the governing and advisory assembly of the aristocracy in the ancient Roman Republic. It was not an elected body, but one whose members were appointed by the consuls, and later by the censors, which were appointed by the aristocratic Centuriate Assembly. After a Roman magistrate served his term in office, it usually was followed with automatic appointment to the Senate. According to the Greek historian Polybius, the principal source on the Constitution of the Roman Republic, the Roman Senate was the predominant branch of government. Polybius noted that it was the consuls (the highest-ranking of the regular magistrates) who led the armies and the civil government in Rome, and it was the Roman assemblies which had the ultimate authority over elections, legislation, and criminal trials. However, since the Senate controlled money, administration, and the details of foreign policy, it had the most control over day-to-day life. The power and authority of the Senate derived from precedent, the high caliber and prestige of the senators, and the Senate's unbroken lineage, which dated back to the founding of the Republic in 509 BC. It developed from the Senate of the Roman Kingdom, and became the Senate of the Roman Empire.

Originally the chief magistrates, the consuls, appointed all new senators. They also had the power to remove individuals from the Senate. Around the year 318 BC, the "Ovinian Plebiscite" (plebiscitum Ovinium) gave this power to another Roman magistrate, the censor, who retained this power until the end of the Roman Republic. This law also required the censors to appoint any newly elected magistrate to the Senate. Thus, after this point in time, election to magisterial office resulted in automatic Senate membership. The appointment was for life, although the censor could impeach any senator.

The Roman magistrates (Latin: magistratus) were elected officials in ancient Rome. During the period of the Roman Kingdom, the King of Rome was the principal executive magistrate. His power, in practice, was absolute. He was the chief priest, lawgiver, judge, and the sole commander of the army. When the king died, his power reverted to the Roman Senate, which then chose an Interrex to facilitate the election of a new king.

During the transition from the Roman Kingdom to Roman Republic, the constitutional balance of power shifted from the executive (the Roman king) to the Roman Senate. When the Roman Republic was founded in 509 BC, the powers that had been held by the king were transferred to the Roman consuls, of which two were to be elected each year. Magistrates of the republic were elected by the people of Rome, and were each vested with a degree of power called "major powers" (maior potestas). Dictators had more "major powers" than any other magistrate, and after the dictator was the censor, and then the consul, and then the praetor, and then the curule aedile, and then the quaestor. Any magistrate could obstruct ("veto") an action that was being taken by a magistrate with an equal or lower degree of magisterial powers. By definition, plebeian tribunes and plebeian aediles were technically not magistrates since they were elected only by the plebeians, and plebeian tribunes could veto the actions of any ordinary magistrate.
