Sisenand or Sisinand (Gothic: Sisinanþs; Spanish, Galician, and Portuguese: Sisenando; Latin: Sisenadus) (c. 605 – 12 March 636) was a Visigothic King of Hispania, Septimania and Galicia from 631 to 636.
Sisenand overthrew Suintila with the aid of Dagobert I, King of the Franks, to whom Gothic nobles offered a plate of pure gold weighing 500 pounds. It is allegedly a gift that Aetius, a roman general, gave to Thorismund, the king of the Visigoths in 451.
He was the one to summon the IV Council of Toledo, which drew up civil and ecclesiastical laws within the Visigothic Kingdom, and succeeded in increasing the power of the king. During his election to kingship, he had Suintila, the previous king, declared a tyrant for his many crimes, iniquity, and accumulation of wealth at the expense of the poor while also removing all taxes on the clergy. However, the council did not concede any hereditary right to the king; the next king would be elected by the bishops and magnates from one of their own.
Between 632 and 633, there was a rebellion led by Iudila. It wasn't mentioned in any records, it is only attested to by two coins from Mérida and Granada bearing the inscription IUDILA REX.
Sisenand died in the city of Toledo on March 12, 636.
