Tiberius Sempronius Gracchus (Latin: TI·SEMPRONIVS·TI·F·P·N·GRACCVS; born c. 169–164 – c. 133 BC) was a Roman Popularis politician of the 2nd century BC, together with Gaius Gracchus, one of the Gracchi brothers. As a plebeian tribune, he caused political turmoil in the Republic with his reforms of agrarian legislation that sought to transfer wealth from the wealthy, patricians and otherwise, to the poor.
