Gaius's Life and Work in Rome

Like Tiberius, Gaius began his career attached to the staff of their much older brother-in-law Scipio Emilianus. In 126 BC, he was elected Quester and was assigned by Lot to a post in Sardinia. But it was on the island that Gaius found himself becoming personally embittered towards the Senate for slights directed at him personally. He returned to Rome, and in 123 BC was elected Tribune of the Plebs like his father and brother before him. His sources differ as to whether Gaius entered office with a revolutionary slate of proposals in hand, or whether his platform grew organically as a response to circumstance.
