Leo III

Leo III, Leon III, or Levon III may refer to:

Pope Leo III

Pope Saint Leo III (Unknown – 12 June 816 AD) was Pope from 795 to his death in 816. Protected by Charlemagne from his enemies in Rome, he subsequently strengthened Charlemagne's position by crowning him Holy Roman Emperor and "Augustus of the Romans".

Biography

Early life and pontifical selection

Leo was a Roman, the son of Atyuppius and Elizabeth. At the time of his election he was Cardinal-Priest of Santa Susanna, and seemingly also vestiarius, or chief of the pontifical treasury, or wardrobe.

He was elected on the very day his predecessor, Adrian I, was buried (26 Dec., 795), and consecrated on the following day. It is quite possible that this haste may have been due to a desire on the part of the Romans to anticipate any interference of the Franks with their freedom of election. With the letter informing Charlemagne that he had been unanimously elected pope, Leo sent him the keys of the confession of St. Peter, and the standard of the city, and requested an envoy. This he did to show that he regarded the Frankish king as the protector of the Holy See.

Leo III the Isaurian

Leo III the Isaurian also known as the Syrian (Greek: Λέων Γ΄ ὁ Ἴσαυρος, Leōn III ho Isauros), (c. 685 – 18 June 741) was Byzantine Emperor from 717 until his death in 741. He put an end to a period of instability, successfully defended the Empire against the invading Umayyads, and forbade the veneration of icons.

Life

Early life

Leo, whose original name was Konon, was born in Germanikeia in the Syrian province of Commagene (modern Kahramanmaraş in Turkey). Some, including the Byzantine chronicler Theophanes, have claimed that Konon's family had been resettled in Thrace, where he entered the service of Emperor Justinian II, when the latter was advancing on Constantinople with an army of 100,000 horsemen provided by Tervel of Bulgaria in 705.

After the victory of Justinian II, Konon was dispatched on a diplomatic mission to Alania and Lazica to organize an alliance against the Umayyad Caliphate under Al-Walid I. Konon was appointed commander (stratēgos) of the Anatolic theme by Emperor Anastasius II. On his deposition, Konon joined with his colleague Artabasdus, the stratēgos of the Armeniac theme, in conspiring to overthrow the new Emperor Theodosius III. Artabasdus was betrothed to Anna, daughter of Leo as part of the agreement.
