Mark Antony is a character from Shakespeare's <em>Julius Caesar</em>. He is Caesar's supporter and friend. It is due to his support that Caesar managed to become as successful as he is, and to be the ruler of Rome. However, Roman Senators, including Brutus and Cassius, decide to murder Caesar, as he has become too powerful. Upon Caesar's death, Mark Antony delivers a speech which makes people who loved Caesar both sad and angry, weakens the conspirators' control, and affects the emotions of the audience through the use of demagogic language. Therefore, the purpose of the speech was quite the opposite of befriending and supporting the conspirators.
