Gaius Julius Caesar (12 or 13 July 100 BC – 15 March 44 BC) was a Roman general, statesman, and author who was the dictator of the Roman Republic almost continuously from 49 BC until his assassination in 44 BC. A member of the First Triumvirate, he led the Roman armies through the Gallic Wars and defeated his political rival Pompey in Caesar's civil war. He consolidated power and was titled as dictator perpetuo in 44 BC, helping create the political conditions that led to the collapse of the Roman Republic and the emergence of the Roman Empire. For his role in these events, he is regarded as one of history's most influential figures.
In 60 BC, Caesar, Crassus, and Pompey formed the First Triumvirate, an informal political alliance that dominated Roman politics for several years. Their attempts to amass political power were opposed by many in the Senate, including Cato the Younger with the private support of Cicero. Caesar rose to become one of the most powerful politicians in the Roman Republic through a string of military victories in the Gallic Wars, completed by 51 BC, which greatly expanded Roman territory. During this time, he invaded Britain and built a bridge across the Rhine. These achievements, along with the loyalty of his veteran army, threatened to eclipse the standing of Pompey. The alliance between Caesar and Pompey slowly broke down and, by 50 BC, Pompey had realigned himself with the Senate. With his command expiring and the Gallic Wars largely concluded, the Senate ordered Caesar to relinquish his military command and return to Rome. In early January 49 BC, Caesar openly defied the Senate by crossing the Rubicon and marching towards Rome at the head of an army. This act began Caesar's civil war, which he won, leaving him in a position of near-unchallenged power and influence in 45 BC.
After assuming control of government and pardoning many of his enemies, Caesar carried out various reforms and public works. He created the Julian calendar to replace the republican lunisolar calendar, reduced the size of the grain dole, settled his veterans in new overseas colonies, greatly increased the size of the Senate, and extended citizenship to communities in Spain and what is now northern Italy. In early 44 BC, he was proclaimed "dictator in perpetuity". Fearful of his power, his domination of the state, and the possibility that he might make himself king, a group of senators led by Brutus and Cassius assassinated Caesar on the Ides of March (15 March) 44 BC. A new series of civil wars broke out and the constitutional government of the Republic was never fully restored. Caesar's great-nephew and adoptive heir Octavian, later known as Augustus, rose to sole power after defeating his opponents thirteen years later. Octavian then set about consolidating his power, transforming the Republic into the Roman Empire as its first emperor.
Caesar was an accomplished author and commentator; much of his life is known through his own accounts of his military campaigns. Other contemporary sources include the letters and speeches of Cicero and the historical writings of Sallust. Later biographies of Caesar by Suetonius and Plutarch are also important sources. Caesar is considered by many historians to be one of the greatest military commanders in history. His cognomen subsequently became a synonym for emperor; the title Caesar was used throughout the Roman Empire, and gave rise to modern derivatives such as Kaiser and Tsar. He has frequently appeared in literary and artistic works.
Early life and career Gaius Julius Caesar was born into a patrician family, the , on 12 or 13 July 100 BC. The family claimed to have immigrated to Rome from Alba Longa during the seventh century BC after the third king of Rome, Tullus Hostilius, took and destroyed their city. The family also claimed descent from Julus, the son of Aeneas and founder of Alba Longa. Given that Aeneas was a son of Venus, this made the clan divine. This genealogy had not yet taken its final form by the first century, but the clan's claimed descent from Venus was well established in public consciousness. There is no evidence that Caesar himself was born by Caesarian section; such operations entailed the death of the mother, but Caesar's mother lived for decades after his birth and no ancient sources record any difficulty with the birth.
Despite their ancient pedigree, the Julii Caesares were not especially politically influential during the middle republic. The first person known to have had the cognomen Caesar was a praetor in 208 BC during the Second Punic War. The family's first consul was in 157 BC, though their political fortunes had recovered in the early first century, producing two consuls in 91 and 90 BC.; Caesar's homonymous father was moderately successful politically. He married Aurelia, a member of the politically influential Aurelii Cottae, producing – along with Caesar – two daughters. Buoyed by his own marriage and the marriage of his sister to the extremely influential Gaius Marius, he also served on the Saturninian land commission in 103 BC and was elected praetor some time between 92 and 85 BC; he served as proconsular governor of Asia for two years, likely 91–90 BC. dates the land commission to 103 per MRR 3.109; ; , dating the proconsulship to 91 with praetorship in 92 BC and citing, among others, and .
Life under Sulla and military service
Caesar's father did not seek a consulship during the domination of Lucius Cornelius Cinna and instead chose retirement. During Cinna's dominance, Caesar was named as flamen Dialis (a priest of Jupiter) which led to his marriage to Cinna's daughter, Cornelia. The religious taboos of the priesthood would have forced Caesar to forgo a political career; the appointment – one of the highest non-political honours – indicates that there were few expectations of a major career for Caesar. In early 84 BC, Caesar's father died suddenly. After Sulla's victory in the civil war (82 BC), Cinna's acta were annulled. Sulla consequently ordered Caesar to abdicate and divorce Cinna's daughter. Caesar refused, implicitly questioning the legitimacy of Sulla's annulment. Sulla may have put Caesar on the proscription lists, though scholars are mixed., stating Caesar was placed on the lists. Cf, stating Caesar was only summoned for interrogation, Caesar then went into hiding before his relatives and contacts among the Vestal Virgins were able to intercede on his behalf. They then reached a compromise where Caesar would resign his priesthood but keep his wife and chattels; Sulla's alleged remark he saw "in [Caesar] many Mariuses"; . is apocryphal.
Caesar then left Italy to serve in the staff of the governor of Asia, Marcus Minucius Thermus. While there, he travelled to Bithynia to collect naval reinforcements and stayed some time as a guest of the king, Nicomedes IV, though later invective connected Caesar to a homosexual relation with the monarch.; ; . He then served at the Siege of Mytilene where he won the civic crown for saving the life of a fellow citizen in battle. The privileges of the crown – the Senate was supposed to stand on a holder's entrance and holders were permitted to wear the crown at public occasions – whetted Caesar's appetite for honours. After the capture of Mytilene, Caesar transferred to the staff of Publius Servilius Vatia in Cilicia before learning of Sulla's death in 78 BC and returning home immediately. He was alleged to have wanted to join in on the consul Lepidus' revolt that year, citing . but this is likely literary embellishment of Caesar's desire for tyranny from a young age.
Afterward, Caesar attacked some of the Sullan aristocracy in the courts but was unsuccessful in his attempted prosecution of Gnaeus Cornelius Dolabella in 77 BC, who had recently returned from a proconsulship in Macedonia. Going after a less well-connected senator, he was successful the next year in prosecuting Gaius Antonius Hybrida (later consul in 63 BC) for profiteering from the proscriptions but was forestalled when a tribune interceded on Antonius' behalf. (Trial 140) noting also that Tac. Dial., 34.7 wrongly places the trial in 79 BC; (Trial 141). After these oratorical attempts, Caesar left Rome for Rhodes seeking the tutelage of the rhetorician Apollonius Molon. While travelling, he was intercepted and ransomed by pirates in a story that was later much embellished. According to Plutarch and Suetonius, he was freed after paying a ransom of fifty talents and responded by returning with a fleet to capture and execute the pirates. The recorded sum for the ransom is literary embellishment and it is more likely that the pirates were sold into slavery per Velleius Paterculus. reports that the governor wanted to enslave and sell the pirates but that Caesar returned quickly and had them executed. Pelling believes the second part of Vell. Pat.'s narrative – along with other sources (; ) – are literary embellishment and that the pirates were enslaved and sold. His studies were interrupted by the outbreak of the Third Mithridatic War over the winter of 75 and 74 BC; Caesar is alleged to have gone around collecting troops in the province at the locals' expense and leading them successfully against Mithridates' forces.
Entrance to politics While absent from Rome, in 73 BC, Caesar was co-opted into the pontifices in place of his deceased relative Gaius Aurelius Cotta. The promotion marked him as a well-accepted member of the aristocracy with great future prospects in his political career. Caesar decided to return shortly thereafter and on his return was elected one of the military tribunes for 71 BC.; ; (pontificate); and (military tribunate). There is no evidence that Caesar served in war – even though the war on Spartacus was ongoing – during his term; he did, however, agitate for the removal of Sulla's disabilities on the plebeian tribunate and for those who supported Lepidus' revolt to be pardoned., citing . These advocacies were common and uncontroversial. The next year, 70 BC, Pompey and Crassus were consuls and brought legislation restoring the plebeian tribunate's rights; one of the tribunes, with Caesar supporting, then brought legislation pardoning the Lepidan exiles.;
For his quaestorship in 69 BC, Caesar was allotted to serve under Gaius Antistius Vetus in Hispania Ulterior. His election also gave him a lifetime seat in the Senate. However, before he left, his aunt Julia, the widow of Marius, died; and, soon afterwards, his wife Cornelia died shortly after bearing his only legitimate child, Julia. He gave eulogies for both at public funerals.; . cites for the incipit of Caesar's eulogy. During his aunt's funeral, Caesar displayed the images of Marius, whose memory had been suppressed after Sulla's victory in the civil war. Some of the Sullan nobles – including Quintus Lutatius Catulus – who had suffered under the Marian regime objected, but by this point depictions of husbands in aristocratic women's funerary processions was common. Contra Plutarch, Caesar's action here was likely in keeping with a political trend for reconciliation and normalisation rather than a display of renewed factionalism. Caesar quickly remarried, taking the hand of Sulla's granddaughter Pompeia.
Aedileship and election as pontifex maximus For much of this period, Caesar was one of Pompey's supporters. Caesar joined with Pompey in the late 70s to support restoration of tribunician rights; his support for the law recalling the Lepidan exiles may have been related to the same tribune's bill to grant lands to Pompey's veterans. Caesar also supported the lex Gabinia in 67 BC granting Pompey an extraordinary command against piracy in the Mediterranean and also supported the lex Manilia in 66 BC to reassign the Third Mithridatic War from its then-commander Lucullus to Pompey.
