Roman consul in the context of "Pompey"

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 overthrow of the Roman monarchy was an event in ancient Rome that took place between the 6th and 5th centuries BC where a political revolution replaced the then-existing Roman monarchy under Lucius Tarquinius Superbus with a republic. The details of the event were largely forgotten by the Romans a few centuries later; later Roman historians presented a narrative of the events, traditionally dated to c. 509 BC, but it is largely believed by modern scholars to be fictitious.

The traditional account portrays a dynastic struggle in which the king's second son, Sextus Tarquinius, rapes a noblewoman, Lucretia. Upon revealing the assault to some Roman noblemen, she kills herself. The Roman noblemen, led by Lucius Junius Brutus, obtain the support of the Roman aristocracy and the people to expel the king and his family and create a republic. The Roman army, supporting Brutus, forces the king into exile. Despite a number of attempts by Lucius Tarquinius Superbus to reinstate the monarchy, the Roman people are successful in establishing a republic and thereafter elected two consuls annually to rule the city.

The War of Actium (32–30 BC) was the last civil war of the Roman Republic, fought between Mark Antony (assisted by Cleopatra and by extension Ptolemaic Egypt) and Octavian. In 32 BC, Octavian convinced the Roman Senate to declare war on the Egyptian queen Cleopatra. Her lover and ally Mark Antony, who was Octavian's rival, gave his support for her cause. Forty percent of the Roman Senate, together with both consuls, left Rome to join the war on Antony's side. After a decisive victory for Octavian at the Battle of Actium, Cleopatra and Antony withdrew to Alexandria, where Octavian besieged the city until both Antony and Cleopatra were forced to commit suicide.

The war involved some of the largest Roman armies ever seen. Both Antony and Octavian's legions were experienced veterans of previous civil wars who had fought together, many also having once served under Julius Caesar. The two did however raise their own legions separately.

In ancient Rome, imperium was a form of authority held by a citizen to control a military or governmental entity. It is distinct from auctoritas and potestas, different and generally inferior types of power in the Roman Republic and Empire. One's imperium could be over a specific military unit, or it could be over a province or territory. Individuals given such power were referred to as curule magistrates or promagistrates. These included the curule aedile, the praetor, the consul, the magister equitum, and the dictator. In a general sense, imperium was the scope of someone's power, and could include anything, such as public office, commerce, political influence, or wealth.

A legate (Latin: legatus, Classical Latin: [ɫeːˈɡaːtʊs]) was a high-ranking military officer in the Roman army, equivalent to a modern-era general officer. Initially used to delegate power, the term became formalised under Augustus as the officer in command of a Roman legion.

From the times of the Roman Republic, legates received large shares of the military's rewards at the end of a successful campaign. This made the position a lucrative one, so it could often attract even distinguished consuls or other high-ranking political figures within Roman politics (e.g., the consul Lucius Julius Caesar volunteered late in the Gallic Wars as a legate under his first cousin, Gaius Julius Caesar).

Marcus Aurelius Antoninus (/ɔːˈriːliəs/ or-EE-lee-əs, Latin: [ˈmaːrkʊs au̯ˈreːli.us antoːˈniːnʊs]; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher. He was a member of the Nerva–Antonine dynasty, the last of the rulers later known as the Five Good Emperors and the last emperor of the Pax Romana, an age of relative peace, calm, and stability for the Roman Empire lasting from 27 BC to 180 AD. He served as Roman consul in 140, 145, and 161.

Marcus Aurelius was the son of the praetor Marcus Annius Verus and his wife, Domitia Calvilla. He was related through marriage to the emperors Trajan and Hadrian. Marcus was three when his father died, and was raised by his mother and paternal grandfather. After Hadrian's adoptive son, Aelius Caesar, died in 138, Hadrian adopted Marcus's uncle Antoninus Pius as his new heir. In turn, Antoninus adopted Marcus and Lucius, the son of Aelius. Hadrian died that year, and Antoninus became emperor. Now heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto. He married Antoninus's daughter Faustina in 145.

Lucius Cornelius Sulla Felix (/ˈsʌlə/, Latin pronunciation: [ˈɫuːkius kɔrˈneːlius ˈsulːa ˈfeːliːks]; 138–78 BC), commonly known as Sulla, was a Roman general and statesman of the late Roman Republic. Coming to fame for his military exploits, he was the first general during the late republic to march on Rome and win a civil war. After purging his opponents, he assumed the dictatorship, sought to strengthen the republican system by means of reforms to the constitution, and resigned his plenary powers after their enactment.

Sulla held the office of consul twice and revived the dictatorship. A gifted general, he achieved successes in wars against foreign and domestic opponents. Sulla rose to prominence during the war against the Numidian king Jugurtha, whom he captured as a result of Jugurtha's betrayal by the king's allies, although his superior Gaius Marius took credit for ending the war. He then fought successfully against Germanic tribes during the Cimbrian War, and Italian allies during the Social War. He was awarded the Grass Crown for his bravery at the Battle of Nola. Sulla was closely associated with Venus, adopting the title Epaphroditos, meaning favoured of Aphrodite.

Constans II (Greek: Κώνστας, romanized: Kōnstās; 7 November 630 – 15 July 668), also called "the Bearded" (Greek: ὁ Πωγωνᾶτος, romanized: ho Pōgōnãtos), was the Byzantine emperor from 641 to 668. Constans was the last attested emperor to serve as consul, in 642, although the office continued to exist until the reign of Leo VI the Wise (r. 886–912). His religious policy saw him steering a middle line in disputes between the Orthodox and Monothelites by refusing to persecute either and prohibited discussion of the natures of Jesus Christ under the Typos of Constans in 648. His reign coincided with Arab invasions under Umar, Uthman, and Mu'awiya I in the late 640s to 660s. Constans was the first emperor to visit Rome since the fall of the Western Roman Empire in 476, and the last one to visit Rome while the Empire still held it.

Marcus Tullius Cicero (/ˈsɪsəroʊ/ SISS-ə-roh; Latin: [ˈmaːrkʊs ˈtʊlli.ʊs ˈkɪkɛroː]; 3 January 106 BC – 7 December 43 BC) was a Roman statesman, lawyer, scholar, philosopher, orator, writer and Academic skeptic, who tried to uphold optimate principles during the political crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics. He is considered one of Rome's greatest orators and prose stylists and the innovator of what became known as "Ciceronian rhetoric". Cicero was educated in Rome and in Greece. He came from a wealthy municipal family of the Roman equestrian order, and served as consul in 63 BC.

He greatly influenced both ancient and modern reception of the Latin language. A substantial part of his work has survived, and he was admired by both ancient and modern authors alike. Cicero adapted the arguments of the chief schools of Hellenistic philosophy in Latin and coined a large portion of Latin philosophical vocabulary via lexical innovation (e.g. neologisms such as evidentia, generator, humanitas, infinitio, qualitas, quantitas), almost 150 of which were the result of translating Greek philosophical terms.

The Varronian chronology is the commonly accepted chronology of early Roman history named after the Roman antiquarian Marcus Terentius Varro. It is from this chronology that the commonly used dates for the foundation of the city (753 BC), the overthrow of the monarchy (509 BC), the Decimvirates (451–450 BC), the Gallic sack of Rome (390 BC), and the first plebeian consul (366 BC) are derived. The chronology consists of an ordered list of magisterial colleges (eg pairs of consuls) which, in modern times, are regularly assigned to years BC.

The years given by the Varronian chronology prior to 300 BC should not be accepted as absolute dates. Years in the chronology are also demonstrably incorrect and it flows four years prior to actual events by 340 BC. Moreover, Roman historians and antiquarians (most especially Livy and Dionysius of Halicarnassus) also did not all use Varro's scheme. Because both the ordering and absolute position of Varronian years is not well established for this early period, the numeric years derived from it should be taken as "no more than numerical symbols for specific consular years".
