Question: When did the man who said "I came; I saw; I conquered" die?

full_context: Document 1: Roman Republic: After the assassination, Mark Antony formed an alliance with Caesar's adopted son and great-nephew, Gaius Octavian. Along with Marcus Lepidus, they formed an alliance known as the Second Triumvirate. They held powers that were nearly identical to the powers that Caesar had held under his constitution. As such, the Senate and assemblies remained powerless, even after Caesar had been assassinated. The conspirators were then defeated at the Battle of Philippi in 42 BC. Eventually, however, Antony and Octavian fought against each other in one last battle. Antony was defeated in the naval Battle of Actium in 31 BC, and he committed suicide with his lover, Cleopatra. In 29 BC, Octavian returned to Rome as the unchallenged master of the Empire and later accepted the title of Augustus ("Exalted One"). He was convinced that only a single strong ruler could restore order in Rome.
Document 2: Roman Republic: Caesar was now the primary figure of the Roman state, enforcing and entrenching his powers. His enemies feared that he had ambitions to become an autocratic ruler. Arguing that the Roman Republic was in danger, a group of senators hatched a conspiracy and assassinated Caesar at a meeting of the Senate in March 44 BC.  Mark Antony, Caesar's lieutenant, condemned Caesar's assassination, and war broke out between the two factions. Antony was denounced as a public enemy, and Caesar's adopted son and chosen heir, Gaius Octavianus, was entrusted with the command of the war against him. At the Battle of Mutina Mark Antony was defeated by the consuls Hirtius and Pansa, who were both killed.
Document 3: Roman Republic: Clodius formed armed gangs that terrorised the city and eventually began to attack Pompey's followers, who in response funded counter-gangs formed by Titus Annius Milo. The political alliance of the triumvirate was crumbling. Domitius Ahenobarbus ran for the consulship in 55 BC promising to take Caesar's command from him. Eventually, the triumvirate was renewed at Lucca. Pompey and Crassus were promised the consulship in 55 BC, and Caesar's term as governor was extended for five years. Crassus led an ill-fated expedition with legions led by his son, Caesar's lieutenant, against the Kingdom of Parthia. This resulted in his defeat and death at the Battle of Carrhae. Finally, Pompey's wife, Julia, who was Caesar's daughter, died in childbirth. This event severed the last remaining bond between Pompey and Caesar.
Document 4: Roman Republic: Caesar held both the dictatorship and the tribunate, and alternated between the consulship and the proconsulship. In 48 BC, Caesar was given permanent tribunician powers. This made his person sacrosanct, gave him the power to veto the senate, and allowed him to dominate the Plebeian Council. In 46 BC, Caesar was given censorial powers, which he used to fill the senate with his own partisans. Caesar then raised the membership of the Senate to 900. This robbed the senatorial aristocracy of its prestige, and made it increasingly subservient to him. While the assemblies continued to meet, he submitted all candidates to the assemblies for election, and all bills to the assemblies for enactment. Thus, the assemblies became powerless and were unable to oppose him.
Document 5: Divide and rule: The maxim divide et impera has been attributed to Philip II of Macedon, and together with the maxim divide ut regnes was utilised by the Roman ruler Caesar and the French emperor Napoleon.
Document 6: Roman Republic: However, civil war flared again when the Second Triumvirate of Octavian, Lepidus and Mark Antony failed. The ambitious Octavian built a power base of patronage and then launched a campaign against Mark Antony. At the naval Battle of Actium off the coast of Greece, Octavian decisively defeated Antony and Cleopatra. Octavian was granted a series of special powers including sole "imperium" within the city of Rome, permanent consular powers and credit for every Roman military victory, since all future generals were assumed to be acting under his command. In 27 BC Octavian was granted the use of the names "Augustus" and "Princeps", indicating his primary status above all other Romans, and he adopted the title "Imperator Caesar" making him the first Roman Emperor.
Document 7: Et tu, Brute?: Et tu, Brute? (pronounced (ɛt ˈtuː ˈbruːtɛ)) is a Latin phrase meaning ``and you, Brutus? '', made famous by its occurrence in William Shakespeare's play Julius Caesar, where it is uttered by the Roman dictator Julius Caesar to his friend Marcus Brutus at the moment of the former's assassination. The Latin expression first occurs in Elizabethan literary texts. The quotation is widely used in the English - speaking world to signify the unexpected betrayal by a person, such as a friend.
Document 8: Virgil: The Georgics' tone wavers between optimism and pessimism, sparking critical debate on the poet's intentions, but the work lays the foundations for later didactic poetry. Virgil and Maecenas are said to have taken turns reading the Georgics to Octavian upon his return from defeating Antony and Cleopatra at the Battle of Actium in 31 BC.
Document 9: Roman Republic: By 59 BC an unofficial political alliance known as the First Triumvirate was formed between Gaius Julius Caesar, Marcus Licinius Crassus, and Gnaeus Pompeius Magnus ("Pompey the Great") to share power and influence. In 53 BC, Crassus launched a Roman invasion of the Parthian Empire (modern Iraq and Iran). After initial successes, he marched his army deep into the desert; but here his army was cut off deep in enemy territory, surrounded and slaughtered at the Battle of Carrhae in which Crassus himself perished. The death of Crassus removed some of the balance in the Triumvirate and, consequently, Caesar and Pompey began to move apart. While Caesar was fighting in Gaul, Pompey proceeded with a legislative agenda for Rome that revealed that he was at best ambivalent towards Caesar and perhaps now covertly allied with Caesar's political enemies. In 51 BC, some Roman senators demanded that Caesar not be permitted to stand for consul unless he turned over control of his armies to the state, which would have left Caesar defenceless before his enemies. Caesar chose civil war over laying down his command and facing trial.
Document 10: Battle of Pharsalus: The Battle of Pharsalus was the decisive battle of Caesar's Civil War. On 9 August 48 BC at Pharsalus in central Greece, Gaius Julius Caesar and his allies formed up opposite the army of the republic under the command of Gnaeus Pompeius Magnus ("Pompey the Great"). Pompey had the backing of a majority of the senators, of whom many were optimates, and his army significantly outnumbered the veteran Caesarian legions.
Document 11: Veni, vidi, vici: Veni, vidi, vici (Classical Latin: (ˈweːniː ˈwiːdiː ˈwiːkiː); Ecclesiastical Latin: (ˈvɛni ˈvidi ˈvitʃi); ``I came; I saw; I conquered '') is a Latin phrase popularly attributed to Julius Caesar who, according to Appian, used the phrase in a letter to the Roman Senate around 47 BC after he had achieved a quick victory in his short war against Pharnaces II of Pontus at the Battle of Zela. The phrase is used to refer to a swift, conclusive victory.
Document 12: Assassination of Julius Caesar: Two days after the assassination, Mark Antony summoned the senate and managed to work out a compromise in which the assassins would not be punished for their acts, but all of Caesar's appointments would remain valid. By doing this, Antony most likely hoped to avoid large cracks in government forming as a result of Caesar's death. Simultaneously, Antony diminished the goals of the conspirators. The result unforeseen by the assassins was that Caesar's death precipitated the end of the Roman Republic. The Roman lower classes, with whom Caesar was popular, became enraged that a small group of aristocrats had sacrificed Caesar. Antony, who had been drifting apart from Caesar, capitalised on the grief of the Roman mob and threatened to unleash them on the Optimates, perhaps with the intent of taking control of Rome himself. But, to his surprise and chagrin, Caesar had named his grandnephew Gaius Octavius his sole heir, bequeathing him the immensely potent Caesar name as well as making him one of the wealthiest citizens in the Republic. Upon hearing of his adopted father's death, Octavius abandoned his studies in Apollonia and sailed across the Adriatic Sea to Brundisium. Octavius became Gaius Julius Caesar Octavianus or Octavian, the son of the great Caesar, and consequently also inherited the loyalty of much of the Roman populace. Octavian, aged only 18 at the time of Caesar's death, proved to have considerable political skills, and while Antony dealt with Decimus Brutus in the first round of the new civil wars, Octavian consolidated his tenuous position. Antony did not initially consider Octavius a true political threat due to his young age and inexperience, but Octavius quickly gained the support and admiration of Caesar's friends and supporters.
Document 13: Greece: The process was completed in 27 BC when the Roman Emperor Augustus annexed the rest of Greece and constituted it as the senatorial province of Achaea. Despite their military superiority, the Romans admired and became heavily influenced by the achievements of Greek culture, hence Horace's famous statement: Graecia capta ferum victorem cepit ("Greece, although captured, took its wild conqueror captive"). The epics of Homer inspired the Aeneid of Virgil, and authors such as Seneca the younger wrote using Greek styles. Roman heroes such as Scipio Africanus, tended to study philosophy and regarded Greek culture and science as an example to be followed. Similarly, most Roman emperors maintained an admiration for things Greek in nature. The Roman Emperor Nero visited Greece in AD 66, and performed at the Ancient Olympic Games, despite the rules against non-Greek participation. Hadrian was also particularly fond of the Greeks; before he became emperor he served as an eponymous archon of Athens.
Document 14: Roman Republic: Beginning in the summer of 54 BC, a wave of political corruption and violence swept Rome. This chaos reached a climax in January of 52 BC, when Clodius was murdered in a gang war by Milo. On 1 January 49 BC, an agent of Caesar presented an ultimatum to the senate. The ultimatum was rejected, and the senate then passed a resolution which declared that if Caesar did not lay down his arms by July of that year, he would be considered an enemy of the Republic. Meanwhile, the senators adopted Pompey as their new champion against Caesar. On 7 January of 49 BC, the senate passed a senatus consultum ultimum, which vested Pompey with dictatorial powers. Pompey's army, however, was composed largely of untested conscripts. On 10 January, Caesar crossed the Rubicon with his veteran army (in violation of Roman laws) and marched towards Rome. Caesar's rapid advance forced Pompey, the consuls and the senate to abandon Rome for Greece. Caesar entered the city unopposed.
Document 15: Veni, vidi, vici: ``Veni, vidi, vici ''(Classical Latin: (ˈweːniː ˈwiːdiː ˈwiːkiː); Ecclesiastical Latin: (ˈvɛni ˈvidi ˈvitʃi);`` I came; I saw; I conquered'') is a Latin phrase popularly attributed to Julius Caesar who, according to Appian, used the phrase in a letter to the Roman Senate around 47 BC after he had achieved a quick victory in his short war against Pharnaces II of Pontus at the Battle of Zela. The phrase is used to refer to a swift, conclusive victory.
