Childebert I
The name "Roussillon" is derived from Ruscino (Rosceliona, Castel Rossello), a small fortified place near modern-day Perpignan where Gaulish chieftains met to consider Hannibal's request for a conference. The region formed part of the Roman province of Gallia Narbonensis from 121 BC to AD 462, when it was ceded with the rest of Septimania to the Visigoth Theodoric II. His successor, Amalaric, on his defeat by Childebert I in 531, retired to Hispania, leaving a governor in Septimania.
