Final answer:
In Shakespeare's 'Julius Caesar,' Brutus is the last person to stab Caesar, an act that was part of a broader conspiracy against Caesar's increasing power.
Step-by-step explanation:
In Shakespeare's play Julius Caesar, the last conspirator to stab Caesar is Marcus Junius Brutus, known simply as Brutus. Caesar's assassination was the result of a conspiracy led by Brutus and Gaius Cassius Longinus, who were former political adversaries of Caesar and had become alarmed by his accumulation of power and indefinite dictatorship, which they saw as a threat to the Republic. Despite their intentions, the assassination did not restore the Republic but instead led to the rise of Caesar's heir, Octavian, and the ensuing conflicts that resulted in the end of the Roman Republic and the beginning of the Roman Empire under the Principate.
