Alaric II
During his youth Catholics were persecuted by the Arian Euric, king of the Visigoths (466-485). Euric's successor, Alaric II (485-507), was tolerant towards them, permitting among other things the creation of Catholic bishoprics, including that of Oloron, of which Gratus was the first bishop. He took part in the Council of Agde in 506, where 34 Catholic bishops of the Visigothic kingdom met under the chairmanship of Saint Caesarius of Arles.
