Quaestor in the context of "Iudicium populi"

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.

Marcus Porcius Cato Uticensis ("of Utica"; /ˈkeɪtoʊ/, KAY-toe; 95 BC – April 46 BC), also known as Cato the Younger (Latin: Cato Minor), was an influential conservative Roman senator during the late Republic. A staunch advocate for liberty and the preservation of the Republic’s principles, he dedicated himself to protecting the traditional Roman values he believed were in decline. A noted orator and a follower of Stoicism, his scrupulous honesty and professed respect for tradition gave him a political following which he mobilised against powerful generals of his day, including Julius Caesar and Pompey.

Before Caesar's civil war, Cato served in a number of political offices. During his urban quaestorship in 63 BC, he was praised for his honesty and incorruptibility in running Rome's finances. He passed laws during his plebeian tribunate in 62 BC to expand the grain dole and force generals to give up their armies and commands before standing in elections. He also frustrated Pompey's ambitions by opposing a bill brought by Pompey's allies to transfer the military command to Pompey against the Catilinarian conspirators. He opposed, with varying success, Caesar's legislative programme during Caesar's first consulship in 59 BC. Leaving for Cyprus the next year, he was praised for his honest administration and after his return was elected as praetor for 54 BC.

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.

The gens Octavia was a plebeian family at ancient Rome, which was raised to patrician status by Caesar during the first century BC. The first member of the gens to achieve prominence was Gnaeus Octavius Rufus, quaestor about 230 BC. Over the following two centuries, the Octavii held many of the highest offices of the state; but the most celebrated of the family was Gaius Octavius, the grandnephew and adopted son of Caesar, who was proclaimed Augustus by the senate in 27 BC.

The Constitution of the Roman Empire was an unwritten set of guidelines and principles passed down mainly through precedent. After the fall of the Roman Republic, the constitutional balance of power shifted from the Roman Senate to the Roman Emperor. Beginning with the first emperor, Augustus, the emperor and the Senate were theoretically two co-equal branches of government. In practice, however, the actual authority of the imperial Senate was negligible, as the emperor held the true power of the state. During the reign of the second emperor, Tiberius, many of the powers that had been held by the Roman assemblies were transferred to the Senate.

The powers of an emperor existed by virtue of his legal standing. The two most significant components to an emperor's power were the "tribunician powers" Latin: tribunicia potestas and the proconsular imperium, or the power to command. The tribunician powers gave the emperor authority over Rome itself and the civil government, while the proconsular powers gave him authority over the provinces and the army. While these distinctions were clearly defined during the early empire, eventually they were lost, and the emperor's powers became less constitutional and more monarchical. The traditional magistracies that survived the fall of the Republic were the Consulship, Praetorship, Plebeian Tribunate, Aedileship, Quaestorship, and Military Tribunate. Any individual of the senatorial class could run for one of these offices. If an individual was not of the senatorial class, he could run for one of these offices if he was allowed to run by the emperor, or otherwise, he could be appointed to one of these offices by the emperor.

The Novellae Constitutiones ("new constitutions"; Ancient Greek: Νεαραὶ διατάξεις, romanized: Nearaì diatáxeis), or Justinian's Novels, are now considered one of the four major units of Roman law initiated by Roman emperor Justinian I in the course of his long reign (AD 527–565). The other three pieces are: the Codex Justinianus, the Digest, and the Institutes. Justinian's quaestor Tribonian was primarily responsible for compiling these last three. Together, the four parts are known as the Corpus Juris Civilis. Whereas the Code, Digest, and Institutes were designed by Justinian as coherent works, the Novels are diverse laws enacted after 534 (when he promulgated the second edition of the Code) that never were officially compiled during his reign.

The executive magistrates of the Roman Republic were officials of the ancient Roman Republic (c. 510 BC – 44 BC), elected by the People of Rome. Ordinary magistrates (magistratus) were divided into several ranks according to their role and the power they wielded: censors, consuls (who functioned as the regular head of state), praetors, curule aediles, and finally 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 as they were elected only by the plebeians, but no ordinary magistrate could veto any of their actions. Dictator was an extraordinary magistrate normally elected in times of emergency (usually military) for a short period. During this period, the dictator's power over the Roman government was absolute, as they were not checked by any institution or magistrate.

Marcus Licinius Crassus (fl. 1st century BC), grandson of the triumvir Marcus Licinius Crassus, was a Roman consul in the year 30 BC as the colleague of Octavian (the future Roman Emperor Augustus). He was best known for his successful campaigns in Macedonia and Thrace in 29–27 BC, for which he was denied customary military honors by Augustus.

The younger Crassus was the son of another Marcus Licinius Crassus, possibly by his wife Caecilia Metella Cretica, daughter of the consul Quintus Caecilius Metellus Creticus (see Caecilius Metellus); his mother's tomb is visible on the Appian Way. His father was a quaestor to Julius Caesar, and a son of Marcus Licinius Crassus possibly by his wife Tertulla (widow of an elder brother killed in December 87 BC). Crassus apparently had no surviving sons by his wife. It is believed that he adopted the future consul Marcus Licinius Crassus Frugi from the Calpurnii Pisones family.

Gnaeus Julius Agricola (/əˈɡrɪkələ/; 13 June 40 – 23 August 93) was a Roman general and politician responsible for much of the Roman conquest of Britain. Born to a political family of senatorial rank, Agricola began his military career as a military tribune under governor Gaius Suetonius Paulinus. In his subsequent career, he served in a variety of political positions in Rome. In 64, he was appointed quaestor in Asia province. Two years later, he was appointed Plebeian Tribune, and in 68, he was made praetor. During the Year of the Four Emperors in 69, he supported Vespasian, general of the Syrian army, in his bid for the throne.

When Vespasian became emperor, Agricola was made a patrician and appointed governor of Gallia Aquitania. In 77, he was made consul and governor of Britannia. As governor, he completed the conquest of what is today Wales and northern England, and led his army to the far north of Scotland, establishing forts across much of the lowlands. In 85, Agricola was recalled from Britain after an unusually lengthy service by Emperor Domitian. After his return, he retired from military and public life and died in 93. Most of what is known about Agricola and his governorship was written in the De vita et moribus Iulii Agricolae, a primary source, written by Tacitus, Agricola's son-in-law, and detailed archaeological evidence from northern Britain.
