Son of Juba I (c. 85-46 b.c.), as a child he had been paraded through the streets of Rome after the defeat of his father. However, Octavian (the future Augustus Caesar; 63 b.c.- a.d. 14) befriended him and in 29 b.c. established him as ruler of Numidia, by then a Roman province. Four years later, Juba additionally became ruler over Mauretania, also a province of Rome.
