Tiberius Sempronius c. 163-133 BC
Roman social reformer. Known with his brother Gaius Sempronius Gracchus (c. 153-121 BC) as “the Gracchi,” he sought to aid poor farmers through greater subdivision of land but was killed in a riot. Gaius assumed his brother's work, initiating several reforms, and met a similar fate.
