The First Citizen represents the voice of Rome’s common people—volatile, easily moved, and swayed by whoever speaks last and loudest. In Act 3, Scene 2, the Forum scene, the First Citizen stands as the archetypal plebeian whose opinion shifts with the wind of rhetoric. When Brutus speaks, the First Citizen is convinced: “I will hear Brutus speak.” He accepts the logical arguments about honor and the necessity of Caesar’s death. But minutes later, after Antony’s masterful funeral oration, the same First Citizen cries for revenge: “We will be revenged.” He demands that Brutus’s house be burned, that the conspirators be hunted down. In fewer than twenty lines, this character embodies Shakespeare’s meditation on how easily reason can be undone by emotion, how the masses can be manipulated by the right words at the right time.
What makes the First Citizen particularly important to the play’s larger argument is his passivity and responsiveness. He does not initiate action; he follows. He does not think independently; he absorbs. When he says, “I will hear Brutus speak,” and later, “We’ll hear Antony,” he reveals himself as a mirror of the crowd’s collective consciousness. He is not evil or stupid—he is simply human, subject to the same forces that move all people: the desire to believe what we are told, the comfort of being part of something larger, the intoxication of righteous anger. Shakespeare uses the First Citizen and his companions to suggest that democracy itself—rule by the people—is only as stable as the people’s ability to reason, and that ability is fragile.
By the end of the play, the First Citizen has vanished from the action, consumed into the mob. But his brief presence serves a crucial function: he shows us that the conspirators’ failure was not merely military but rhetorical. They believed that reason and honor could govern politics, that their words would persuade the people to accept Caesar’s death as necessary sacrifice. The First Citizen proves them wrong. He walks off stage shouting for blood, having forgotten, in the space of a moment, everything Brutus said. In that forgetfulness lies the seed of civil war.
