He strengthened the position of his family and provided for the security of his kingdom by associating his two sons, Recared and Hermenegild, with himself in the kingly office and placing parts of the land under their rule.
His son Hermenegild, however, was converted to the orthodox faith through the influence of his Frankish wife, Ingundis, daughter of King Sigebert I., and of Leander, metropolitan of Seville.
Hermenegild was captured; he refused to give up his faith and in March or April 585 he was executed.
Ingunda the Frankish wife of Hermenegild, with the help of Leandro, archbishop of Seville, the brother and predecessor of the more famous Isidore (q.v.), persuaded her husband to renounce Arianism.
