Tiberius Gracchus' younger brother Gaius Gracchus, who later was to win repeated office to the tribunate so to pass similarly expansive reforms, would be killed by similar violence. Consul Lucius Opimius was empowered by the senate to use military force (including a number of foreign mercenaries from Crete) in a state of emergency declared so to kill Gaius Gracchus, Marcus Fulvius Flaccus and followers. While the citizens killed in the political violence were not declared enemies, it showed clearly that the aristocracy believed violence was a "logical and more effective alternative to political engagement, negotiation, and compromise within the parameters set by existing norms".
