The Chronicon Mundi of Lucas Tudensis records the succession "Era DCLXI imperii Heraclii octavo" of "Suintila filius Reccaredi Regis". Isidore of Seville records that Suíntila succeeded "in the era 659 (621)" after "having risen to the position of general under king Sisebut [and] captured Roman fortresses and overcame the Ruccones".
He succeeded in 621 as SUÍNTILA King of the Visigoths. Isidore of Seville states that Suíntila "obtained all the remaining cities which the Roman army held in Spain…[and] was the first to obtain the monarchy of the entire kingdom of Spain north of the straits". Fredegar records that "Sintela" succeeded on the death of "Sisebodo regis", commenting that he was "very harsh to his followers and hated by all the magnates of his kingdom".
The Chronica Regum Visigotthorum records that “Suinthila” reigned for ten years. 1
