- Tiberius was a Roman politician of the 2nd century BC and brother of Gaius Gracchus. As a plebeian tribune, his reforms of agrarian legislation caused political turmoil in the Republic. These reforms threatened the holdings of rich landowners in Italy.
- Seeking to improve the lot of the poor, Tiberius Gracchus proposed a law known as Lex Sempronia Agraria. The law would reorganize control of the ager publicus, or public land; meaning land conquered in previous wars that was controlled by the state.
