Final answer:
Tiberius and Gaius Gracchus were killed after passing reform bills to help the poor. Tiberius wanted to redistribute public land to landless Romans, while Gaius sought to extend citizenship to all Italians. Their actions faced opposition from the Senate.
Step-by-step explanation:
Tiberius and Gaius Gracchus were killed after they had the council pass reform bills to help the poor. Tiberius, as a tribune, proposed a law to distribute public land to landless Romans, which struck a blow at the senatorial class and violated the traditions of the Republic. Gaius, also a tribune, attacked corruption in the provinces and tried to extend full citizenship to all of Rome's Italian subjects. Both brothers faced opposition from the Senate and ultimately met a violent end.
