Athanagild

Athanagild, having risen against King Agila, called in the Byzantines and, in payment for the succour they gave him, ceded to them the maritime places of the southeast (554). Liuvigild restored the political unity of the peninsula, subduing the Suebians, but the religious divisions of the country, reaching even the royal family, brought on a civil war. St. Hermengild, the king’s son, putting himself at the head of

the Catholics, was defeated and taken prisoner, and suffered martyrdom for rejecting communion with the Arians. Recared, son of Liuvigild and brother of St. Hermengild, added religious unity to the political unity achieved by his father, accepting the Catholic faith in the Third Council of Toledo (589). The religious unity established by this council was the basis of that fusion of Goths with Hispano-Romans which produced the Spanish nation. Sisebut and Suintila completed the expulsion of the Byzantines from Spain.[24]

Intermarriage between Visigoths and Hispano-Romans was prohibited, though in practice it could not be entirely prevented and was eventually legalised by Liuvigild.[34] The Spanish-Gothic scholars such as Braulio of Zaragoza and Isidore of Seville played an important role in keeping the classical Greek and Roman culture. Isidore was one of the most influential clerics and philosophers in the Middle Ages in Europe, and his theories were also vital to the conversion of the Visigothic Kingdom from an Arian domain to a Catholic one in the Councils of Toledo. Isidore created the first western encyclopedia which had a huge impact during the Middle Ages.[35]
