Who are the people of Rome honoring at the beginning of Julius Caesar?
At the beginning of Julius Caesar, the people are honoring Caesar. There is a triumphant parade. Caesar has defeated the sons of Pompey, an arch rival. The people are celebrating Caesar's victory. The play opens with two tribunes, Flavius and Murellus, scolding the citizens for neglecting their work and removing the decorations from Caesar's statutes.
Caesar enters with his entourage which includes the military and the political figures such as the noble Brutus, Cassius and Antony:
A Soothsayer calls out to Caesar to “beware the Ides of March,” but Caesar ignores him and proceeds with his victory celebration (I.ii.19, I.ii.25).
Indeed, there is a celebration and Caesar is being honored as the play opens. Brutus and Cassius are discussing the dangers of Caesar becoming a dictator. Brutus does fear that Caesar is about to crown himself emperor. Brutus is worried that Caesar has become too ambitious. This leads to Caesar being stabbed by the conspirators on the Ides of March.
