Explanation: The Brothers Gracchi were two reformers in the Late Roman Republic who championed land reform and relief for the urban poor. They were both killed by conservatives, though some of their reforms survived.
Julius Caesar, of conqueror and dictator fame, was also killed by conservatives - but after Caesar was killed, the people of Rome rioted in protest against his killers, unlike the more muted, though sour, response to the extrajudicial killings of the Gracchi.
