Over the years, Rome had expanded along the southern Iberian coast until in 211 BC it captured the city of Saguntum. Following two major military expeditions to Iberia, the Romans finally crushed Carthaginian control of the peninsula in 206 BC, at the Battle of Ilipa, and the peninsula became a Roman province known as Hispania. From 206 BC onwards the only opposition to Roman control of the peninsula came from within the native Celtiberian tribes themselves, whose disunity prevented their security from Roman expansion.
