sentences:  Plutarch told that as the tribunes arrested people for saluting Caesar as King, crowds applauded, calling them Brutuses—not after Marcus Junius Brutus, not yet the assassin of Caesar, but after Lucius Junius Brutus, a possibly apocryphal figure who had led a coup against the despotic last king, Tarquin the Proud, thereby founding the Roman Republic.He also notes that Caesar insulted the tribunes in a speech as he removed them from office, "and in speaking against them he insulted the people at the same time".He appears as the tribune "Flavius" in Shakespeare's biographical play "Julius Caesar".
