120 free Julius Caesar trivia questions with answers — history quiz, new questions added Oct 2026.
62 free Julius Caesar trivia questions with answers. Julius Caesar conquered Gaul, crossed the Rubicon, rewrote the calendar and was stabbed at least twenty-three times in a Senate meeting, and every part of that story is in this quiz. It covers his early life under Sulla and his kidnapping by pirates, the First Triumvirate with Pompey and Crassus, the Gallic Wars and Alesia, the invasions of Britain, the civil war and Pharsalus, Cleopatra and Caesarion, the dictatorship for life, the Ides of March, and what happened to Brutus, Cassius and Octavian afterwards. There is a short section on Shakespeare's play too, since that is how most people first meet him. Easy questions ask which river he crossed and what 'veni, vidi, vici' means; the hard ones want the month that was renamed for him, the astronomer behind his calendar, the number of stab wounds and where the Senate was actually meeting that day. Written for history buffs, students and pub-quiz teams. Every answer was checked against Wikipedia's articles on Caesar, his battles and his assassination, and each question carries the sentence that backs it up.

Q 01Which name did the senators who killed Caesar give themselves?
The Liberators
The Liberators expected the killing to restore the old Republic; instead, anger in the city drove them out of Rome within weeks, and the civil wars that followed ended in one-man rule.
Q 02On which date, known by its Roman calendar name, was Caesar killed?
The Ides of March
The Ides of March had come, Caesar joked on his way in to the seer who had warned him about the day; 'Ay, but not gone,' came the reply.
Q 03Which river did Caesar famously cross with his army in January 49 BC?
The Rubicon
The Rubicon marked the border of his province, and no governor could lawfully lead an army past it into Italy, so crossing it was an act of war; the phrase still means passing a point of no return.
Q 04Caesar's 'the die is cast', famous in Latin, was reportedly spoken in which other language?
Greek
Greek: he was apparently quoting a line by the Athenian playwright Menander, and the famous Latin wording comes from a Roman biographer writing more than a century afterwards.
Q 05In Spain, Caesar reportedly lamented that which conqueror had achieved far more by the same age?
Alexander the Great
Alexander the Great. In one telling Caesar brooded over a history of the king; in another he sighed before his statue at Cádiz, then asked to leave his post early to chase greater things in Rome.
Q 06Along with Caesar, which two men formed the First Triumvirate in 60 BC?
Pompey and Crassus
Pompey and Crassus had been enemies since sharing the consulship, so Caesar first patched up their quarrel; the pact that followed was a private deal between three men, never a formal office.
Q 07Which of Caesar's relatives became Pompey's wife in 59 BC?
His daughter Julia
His daughter Julia died in childbirth in 54 BC, and the family tie between the two men died with her; within five years they were at war.
Q 08Caesar's Gallic Wars all but ended with the surrender of which chieftain at Alesia?
Vercingetorix
Vercingetorix, in the most dramatic ancient telling, rode out in his finest armour, circled the seated Caesar and sat down at his feet; he was held for six years, paraded in Caesar's triumph and then executed.
Q 09At Alesia, Caesar's second wall faced outward against what?
A Gallic relief army
A Gallic relief army attacked from outside while the starving garrison struck from within, so Caesar's men were besiegers and besieged at once; both assaults failed and the town gave up.
Q 10In which long-running European comic series is Julius Caesar the recurring foe?
Asterix
Asterix is set in 50 BC, when one village of Gauls still holds out against Caesar's legions thanks to a druid's magic potion that gives its drinkers superhuman strength.
Q 11Which island did Caesar invade in 55 and 54 BC?
Britain
Britain's tides caught him out: on the first landing a storm and a full-moon high tide his men had not expected wrecked much of the beached fleet, so he came back the next year with a far larger force.
Q 12Across which river did Caesar build a bridge as a show of Roman engineering power?
The Rhine
The Rhine was bridged in just ten days; Caesar marched his army across, spent eighteen days on the far bank, then marched back and cut the bridge down behind him.
Q 13Which migrating tribe did Caesar stop near Geneva in the first engagement of the Gallic Wars?
The Helvetii
The Helvetii had burned their own towns and villages before setting out so that no one would turn back; after beating them, Caesar ordered the survivors home to rebuild.
Q 21What does 'veni, vidi, vici' mean?
I came, I saw, I conquered
I came, I saw, I conquered summed up a war won in a single battle within five days of his arrival; in Latin the three words share one ending, which gives the boast its punch.
Q 22Which staunch republican killed himself at Utica rather than accept Caesar's pardon?
Cato the Younger
Cato the Younger read Plato on the soul, then stabbed himself, and when a doctor stitched the wound he tore it open again; Caesar said he begrudged Cato a death that robbed him of the chance to spare him.
Q 23The last battle of Caesar's civil war, fought in Spain in 45 BC, was at which town?
Munda
Q 14How does Caesar refer to himself throughout his own account of the Gallic Wars?
In the third person
In the third person: it is always 'Caesar' who marches, decides and wins, never 'I', a device that lets a general's account of his own war read like detached reporting while it promotes him.
Q 15A fire started by Caesar's troops in 48 BC is traditionally blamed for damaging which Egyptian landmark?
The Great Library
The Great Library, or part of it, caught fire when flames spread from ships his men had torched in the harbour; how much burned is unclear, and scholars were still at work there decades later.
Q 16At which battle in 48 BC did Caesar decisively defeat Pompey?
Pharsalus
Pharsalus was won against the odds: outnumbered, Caesar hid a fourth line of infantry that jabbed its javelins at Pompey's charging horsemen instead of throwing them, routed the cavalry and turned his flank.
Q 17How did Caesar reportedly react when shown the severed head of his murdered rival Pompey?
He wept
He wept, and far from rewarding the Egyptian courtiers who had ordered the murder to win his favour, he rebuked them and had his rival's head given an honourable burial.
Q 18Which Egyptian queen became Caesar's lover during the Alexandrine war?
Cleopatra
Cleopatra was fighting her brother for the throne when Caesar arrived; he took her side, the young king drowned in the Nile fleeing the final battle, and she was left as queen.
Q 19What nickname was given to the son the Egyptian queen said she had borne Caesar?
Caesarion
Caesarion, 'little Caesar', reigned beside his mother as Egypt's last pharaoh; as her kingdom fell, the 17-year-old fled but did not escape, and the victor had him put to death.
Q 20In Dante's Inferno, Caesar's killers Brutus and Cassius are chewed in Satan's jaws beside which biblical figure?
Judas Iscariot
Judas Iscariot fills the third mouth: Dante put the two assassins at the very bottom of Hell as betrayers of their lord, while Caesar himself stands armed and hawk-eyed among the noble pagans of Limbo.
Munda was so close that Caesar went into the ranks himself to steady his men; afterwards he said he had often fought for victory, but that day, for the first time, for his life.
Q 24Which animal, new to Rome, did Caesar show off at his games?
A giraffe
A giraffe, which the Romans called a camelopard because it looked to them like a camel with a leopard's spots; the hippopotamus and the crocodile had already been shown at earlier games.
Q 25Which Roman month was renamed in Caesar's honour?
Quintilis
Quintilis, literally the 'fifth' month of a year that once began in March, became Julius, our July, because Caesar was born in it; Sextilis was later renamed August.
Q 26As of 2026, the main Orthodox church based in which capital still dates Christmas by Caesar's Julian calendar?
Moscow
Moscow's church still keeps Christmas by Caesar's calendar, which now runs 13 days behind the civil one, so its 25 December falls on everyone else's 7 January; the other three churches moved to a revised calendar last century.
Q 27For his triumphal games in 46 BC, Caesar had a basin dug and flooded in Rome to stage what?
A mock sea battle
A mock sea battle, the first known in Rome: warships crewed by prisoners of war and condemned men fought in earnest, and the crowds at the games were so vast that spectators were crushed to death.
Q 28Caesar's Julian calendar served the West until which pope dropped ten days in 1582?
Gregory XIII
Gregory XIII acted because Caesar's year ran about 11 minutes long, enough to slip ten days against the seasons over the centuries; his fix also drops three leap years in every four hundred.
Q 29Which statesman, kept out of the plot against Caesar, did Brutus call on by name as he raised his bloody dagger?
Cicero
Cicero had not been told, though the plotters counted on his sympathy; Brutus shouted his name once Caesar was dead, and an enemy later used that cry to brand him an accomplice.
Q 30Which two destroyed cities did Caesar refound as Roman colonies?
Carthage and Corinth
Carthage and Corinth had been destroyed by Roman armies in the very same year; a century later Caesar refounded the pair together, keeping the old names in honour of the cities Rome had wiped out.
