Gaius Julius C. f. L. n. Iulus was a Roman statesman, who held the consulship in 482 BC, and a member of the first decemvirate in 451.
As his filiation reveals, Julius was the son of Gaius and grandson of Lucius. His father is generally supposed to have been the same Gaius Julius Iulus who was consul in 489. Although only seven elapsed between the two consulships, this would be perfectly reasonable if the father had been an older man when he achieved the magistracy, and the son attained it while relatively young. Julius also had a brother, Vopiscus, who held the consulship in 473. Julius' son, Gaius Julius Iulus, was consul in 447 BC.
The consular elections for BC 482 were fraught with dissension between the aristocratic and popular parties. The aristocratic candidate was Appius Claudius Sabinus, son of the Appius Claudius who had been consul in 495, and the staunchest opponent of the plebeians. A true son of his father, Claudius was firmly opposed by the popular faction, which preferred older candidates whose even-handedness toward the plebeians had already been proven.
The Tribunes of the Plebs willingly used their veto power to prevent the comitia from meeting to elect Claudius, and there was talk of appointing a dictator, but more moderate voices prevailed, and Aulus Sempronius Atratinus was appointed interrex instead. He was followed by Spurius Lartius, who presided over the election of Gaius Julius Iulus, representing the popular party, and Quintus Fabius Vibulanus for the aristocrats. Fabius had been consul three years earlier, and was acceptable to the plebeians, particularly compared with Claudius.
