Why is the play called Julius Caesar and not The Tragedy of Brutus?

The play Julius Caesar is named after the historical figure Julius Caesar, who is the main protagonist and antagonist of the play. The play focuses on Caesar's rise to power, his assassination, and the subsequent power struggle between his supporters and opponents. Brutus, on the other hand, is a complex and tragic character who plays a significant role in the play, but he is not the central figure or the driving force of the plot. The play's title reflects its focus on Caesar and the wider political and historical events that shape the narrative.
