Pope Zachary (; 679 – March 752) was the bishop of Rome from 28 November 741 to his death. He was the last pope of the Byzantine Papacy. Zachary built the original church of Santa Maria sopra Minerva, forbade the traffic of slaves in Rome, negotiated peace with the Lombards, and sanctioned Pepin the Short's usurpation of the Frankish throne from Childeric III. Zachary is regarded as a capable administrator and a skillful and subtle diplomat in a dangerous time. Early career Zachary was born into a family of Greek origin, in the Calabrian town of Santa Severina. He was most probably a deacon of the Roman Church and as such signed the decrees of the Roman council of 732. He was selected to succeed Gregory III as pope on 3 December or 5 December 741.

"As for Milo and his like, who are doing great injury to the church of God, preach in season and out of season, according to the word of the Apostle, that they cease from their evil ways." At Boniface's request, Zachary confirmed three newly established bishoprics of Würzburg, Büraburg, and Erfurt. In 742 he appointed Boniface as papal legate to the Concilium Germanicum, hosted by Carloman, one of the Frankish mayors of the Palace. In a later letter Zachary confirmed the metropolitans appointed by Boniface to Rouen, Reims, and Sens. In 745 Zachary convened a synod in Rome to discourage a tendency toward the worship of angels. Zachary corresponded with temporal rulers as well.
