This paper examines Julius Caesar as a political tragedy that interrogates the ethics of power, loyalty, and republicanism. Through the character of Brutus, Shakespeare presents political idealism in its most sincere yet flawed form. Brutus justifies Caesar’s assassination as a preventive act against tyranny, believing that the preservation of Rome’s democratic values demands personal sacrifice. However, his moral reasoning is manipulated by Cassius, whose motives are shaped by envy and political rivalry.

The assassination, far from restoring liberty, plunges Rome into chaos and civil war. Mark Antony’s masterful rhetoric exposes the vulnerability of political systems to emotional persuasion and mass psychology. The play thus suggests that betrayal in the name of patriotism can destroy the very ideals it seeks to protect.
