Pope Gregory II
Greek was the language of choice during this period as countless Easterners rose through the ranks of the clergy. According to Ekonomou, between 701 and 750, "Greeks outnumbered Latins by nearly three and a half to one". Any power vacuum was swiftly filled from Rome: for example, Pope Gregory II came to the aid of the exarchate of Ravenna in 729 by helping to crush the rebellion of Tiberius Petasius, and Pope Zacharias in 743 and 749 negotiated the withdrawal of the Lombards from imperial territory.
