Julius Caesar was assassinated in 44 BC on the Ides of March, which corresponds to March 15 on the Roman calendar. A group of Roman senators, fearing Caesar's accumulation of power and potential for dictatorship, conspired to kill him. The assassination took place during a Senate meeting at the Theatre of Pompey. Caesar's death marked a pivotal moment in Roman history, leading to the end of the Roman Republic and the rise of the Roman Empire. His assassination also set off a series of civil wars and ultimately paved the way for the establishment of the imperial rule under Augustus Caesar.
