Rey entre los años 636 y 640, sucedió a Sisenando y convocó los concilios V (636) y VI (638) de Toledo. Los únicos documentos coetáneos que nos arrojan algo de luz sobre sus años de reinado son precisamente las actas de estos concilios. La insistencia que se hace en ellas para proteger la figura y la hacienda del rey, de su familia y de sus allegados permite entrever que hubo de afrontar diversas rebeliones por parte de la nobleza goda, aunque nos es imposible conocer la naturaleza y extensión de éstas. Durante su reinado se dictaron medidas contra los judíos. A su muerte le sucedió, por poco tiempo, su hijo Tulga.
Resumen biográfico extraído de Wikipedia en español: <blockquote>"Chintila (en gótico: Kinþila; ¿? - 639/640) fue rey de los visigodos entre 636 y 639/640. Sabemos muy poco de su reinado, ya que las crónicas son escasas. Casi todo lo que sabemos es por las actas del V y VI Concilio de Toledo. Su nombre también puede encontrarse escrito como Khíntila."</blockquote>
Abstract from English Wikipedia: <blockquote>"Chintila (Gothic: Kinþila); Latin: Chintila, Chintilla, Cintila; c. 606 - 20 December 639 AD) was Visigothic King of Hispania, Septimania and Galicia from 636. He succeeded Sisenand in a time of weakness and reigned until his death. He was elected and confirmed by a convention of bishops and nobles in accordance with the 75th canon of the Fourth Council of Toledo. With his election, nothing changed and instability reigned. He never solved the many problems which plagued his time in office and, as the chroniclers of the age tell us, this included rebellions in Septimania and Gallaecia. In the three years of his reign, he permitted the bishops wide authority and they were the monarchs de facto, if not de jure. He dedicated his time to councils, the Fifth Council of Toledo in June 636 and the Sixth Council of Toledo in June 638. These meetings covered many topics and legislated many new regulations. The king had to be chosen from among the nobility; never a tonsurado (cleric), member of the servile classes (peasants), or foreigners. They dictated the penalties for insurrection and determined that property acquired justly by the king could not be confiscated by his successor. Finally, they outlawed noncatholics within the frontiers of the kingdom, which resulted in many forced conversions. Chintila died in 639 or 640 of natural causes and was followed by his son Tulga."</blockquote>
