Assassination of Julius Caesar participant Decimus Junius Brutus Albinus
Julius Caesar was  assassinated by a group of senators on the Ides of March (15 March) of 44 BC during a meeting of the Senate at the Curia of Pompey of the Theatre of Pompey in Rome where the senators stabbed Caesar 23 times. They claimed to be acting over fears that Caesar's unprecedented concentration of power during his dictatorship was undermining the Roman Republic. At least 60 to 70 senators were party to the conspiracy, led by Marcus Junius Brutus, Gaius Cassius Longinus, and Decimus Junius Brutus Albinus. Despite the death of Caesar, the conspirators were unable to restore the institutions of the Republic. The ramifications of the assassination led to his Martyrdom, the Liberators' civil war and ultimately to the Principate period of the Roman Empire.Ides of March
On the Ides of March of 44 BC, conspirators and non-conspirators met at the Senate House of Pompey, located in the Theatre of Pompey, for the senate meeting. Usually, the senators would be meeting at the Roman Forum, but Caesar was financing a reconstruction of the forum and so the senators met in other venues throughout Rome, this being one of them. There were gladiatorial games underway at the Theatre, and Decimus Brutus, who owned a company of gladiators, stationed them in the Portico of Pompey, also located in the Theatre of Pompey. The gladiators could be useful to the conspirators: if a fight broke out to protect Caesar, the gladiators could intervene; if Caesar was killed but the conspirators came under attack, the gladiators could protect them; and since it was impossible to enter the Senate House without going through the Portico, the gladiators could block entrance to both if necessary.The senators waited for Caesar's arrival, but he did not come. The reason for this is that early that morning, Calpurnia, Caesar's wife, was awoken from a nightmare. She had dreamt that she was holding a murdered Caesar in her arms and mourning him. Other versions have Calpurnia dream that the front pediment of their house had collapsed and that Caesar had died; yet another shows Caesar's body streaming with blood. Calpurnia had no doubt heard Spurinna's warnings of great peril to Caesar's life, which helps explain her visions. Around 5 a.m., Calpurnia begged Caesar not to go to the senate meeting that day. After some hesitation, Caesar acquiesced. Although not superstitious, he knew that Spurinna and Calpurnia were involved in Roman politics, and decided to be cautious. Caesar sent Mark Antony to dismiss the Senate. When the conspirators heard of this dismissal, Decimus went to Caesar's home to try to talk him into coming to the Senate meeting. "What do you say, Caesar?" Decimus said. "Will someone of your stature pay attention to a woman's dreams and the omens of foolish men?" Caesar eventually decided to go.Caesar was walking to the senate house when he caught sight of Spurinna. "Well, the Ides of March have come!" Caesar called out playfully. "Aye, the Ides have come," said Spurinna, "but they are not yet gone." Mark Antony started to enter with Caesar, but was intercepted by one of the plotters (either Trebonius or Decimus Brutus) and detained outside. He remained there until after the assassination, at which point he fled.
According to Plutarch, as Caesar took his seat, Lucius Tillius Cimber presented him with a petition to recall his exiled brother. The other conspirators crowded round to offer their support. Both Plutarch and Suetonius say that Caesar waved him away, but Cimber grabbed Caesar's shoulders and pulled down Caesar's toga. Caesar then cried to Cimber, "Why, this is violence!" ("Ista quidem vis est!"). At the same time, Casca produced his dagger and made a glancing thrust at the dictator's neck. Caesar turned around quickly and caught Casca by the arm. According to Plutarch, he said in Latin, "Casca, you villain, what are you doing?" Casca, frightened, shouted simultaneously "Brother! Help me!" (Ancient Greek: ἀδελφέ, βοήθει, romanized: adelphe, boethei). Though Caesar was able to violently throw Casca away, Gaius Servilius Casca stabbed him in the side. Within moments, Caesar was attacked from all directions, with Cassius, slashing Caesar's face, Bucilianus stabbing at the back and Decimus slicing his thigh. Caesar attempted to fight back, but tripped and fell; the men continued stabbing him as he lay defenseless on the lower steps of the portico. Caesar was stabbed 23 times. Suetonius relates that a physician who performed an autopsy on Caesar established that only one wound (the second one to his ribs) had been fatal. This autopsy report (the earliest known post-mortem report in history) describes that Caesar's death was mostly attributable to blood loss from his stab wounds.Caesar was killed at the base of the Curia of Pompey in the Theatre of Pompey.The dictator's last words are a contested subject among scholars and historians. Suetonius himself says he said nothing, nevertheless, he mentions that others have written that Caesar's last words were the Greek phrase "καὶ σύ, τέκνον;" (transliterated as "Kai su, teknon?": "You too, child?" in English). Plutarch also reports that Caesar said nothing, pulling his toga over his head when he saw Brutus among the conspirators. According to Plutarch, after the assassination, Brutus stepped forward as if to say something to his fellow senators not involved in the plot; they, however, fled the building. Brutus and his companions then marched through the city, announcing: "People of Rome, we are once again free!" They were met with silence, as the citizens of Rome had locked themselves inside their houses as soon as the rumours of what had taken place began to spread. According to Suetonius, after the murder all the conspirators fled; Caesar's body lay untouched for some time afterwards, until finally three slaves put him on a litter and carried him home, with one arm hanging down.
