Chintila never solves the many problems which plague his time in office and, as the chroniclers of the age tell us, this includes rebellions in Septimania and Gallaecia.

In the three years of his reign, he has permitted the bishops wide authority and they are the monarchs de facto, if not de jure.

He has 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 has 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 decided the kings should die in peace, and declared their persons sacred, seeking to end the violence and regicides of the past.

Despite all this, another coup takes place: Chintila is deposed at the end of 639, and Tulga succeeds him.

Moreover, the councils have outlawed non-Catholics within the frontiers of the kingdom, which has resulted in many forced conversions.
