Pope Adeodatus II (c. 621–17 June 676), sometimes called Deodatus, was the bishop of Rome from 672 to his death.
His election was ratified by the exarch of Ravenna within weeks, as required during the period of Byzantine papacy.
It coincided with a surge of passionate interest in Pope Martin I and Maximus the Confessor, who were known for resisting the support of the Eastern Roman emperors for Monothelism.
In light of this, Pope Adeodatus rejected the synodical letters sent to him by Patriarch Constantine I of Constantinople.
[2] Adeodatus was active in improving monastic discipline and in the repression of Monothelitism and gave Venice the right to choose its doge.
