Saint Deusdedit (born, Rome [Italy]—died Nov. 8, 618, Rome) was the pope from 615 to 618. His pontificate is chiefly noteworthy for an unsuccessful resumption of the Byzantine war against the Lombards in Italy and for a reversal of the policy of popes Gregory I and Boniface IV, who favoured monks over the secular clergy. Deusdetit, instead, proved partial to the diocesan, or secular, clergy.
