Michael I Rangabé (also spelled Rangabe or Rhangabe; Greek: Μιχαὴλ Ῥαγγαβέ, romanized: Mikhaḗl Rangabé; c. 770 – 11 January 844) was Byzantine emperor from 811 to 813. A courtier of Emperor Nikephoros I (r. 802–811), he survived the disastrous campaign against the Bulgars and was preferred as imperial successor over Staurakios (r. 811–811), who was severely injured. He was proclaimed emperor by Patriarch Nikephoros I of Constantinople on 2 October 811.

Michael's policies were generally conciliatory, and he was overwhelmingly influenced by the iconodule clerics Nikephoros and Theodore the Stoudite. He improved relations with the Franks, even to the point of recognising Charlemagne as an emperor—although not "of the Romans"—and requesting papal arbitration in the Moechian controversy. His half-hearted leadership of the campaign against the Bulgars resulted in defeat in the Battle of Versinikia. The stratēgos of the Anatolic Theme, Leo the Armenian, a popular and successful general, abandoned Michael on the battlefield but was proclaimed emperor by the military, in what was the last military overthrow of an emperor in Byzantine history. Michael was pressured to abdicate, and he retired to a monastery. His sons were castrated to prevent the continuation of his dynasty.

Michael was the son of the patrician Theophylact Rhangabe, the admiral of the Aegean fleet.^[2] The Rangabé family was of Greek origin.^[3] He married Prokopia, the daughter of the former Emperor Nikephoros I,^[4] and received the high court dignity of kouropalatēs after his father-in-law's accession in 802.

Michael survived Nikephoros' disastrous campaign against Khan Krum of Bulgaria, and was considered a more appropriate candidate for the throne than his severely injured brother-in-law Staurakios, who was proclaimed emperor by the military in the hope that he would recover. When Michael's wife Prokopia failed to persuade her brother Staurakios, who wanted to have him blinded, to name Michael as his successor, a group of senior officials (the magistros Theoktistos, Domestic of the Schools Stephen, and Patriarch Nikephoros I of Constantinople) forced Staurakios to abdicate in his favour on 2 October 811. Michael was proclaimed emperor before the senate and the tagmata.^[5][4][6]

Michael attempted to carry out a policy of reconciliation, abandoning the exacting taxation instituted by Nikephoros I. While reducing imperial income, Michael generously distributed money to the army, the bureaucracy, and the church.^[9] Ruling with the support of the iconodule party in the Church, Michael diligently persecuted the iconoclasts and forced Patriarch Nikephoros to back down in his dispute with Theodore the Stoudite, the influential abbot of the Monastery of Stoudios. He revoked the exile of the Stoudites effected by Emperor Nikephoros, and Theodore became his close confidant.^[10] Michael's piety won him a very positive estimation in the work of the chronicler Theophanes the Confessor. Theophanes also mentions the existence of a group of heretics known as Athinganoi in Phrygia, who were most likely the successors of the Montanists, who Emperor Leo III the Isaurian (r. 717–741) attempted to convert by force, as well as of the Paulicians. Patriarch Nikephoros pressed Michael to organise the persecution and execution of the Athinganoi, Paulicians and iconoclast abbots.^[11] But when Nikephoros insisted the heretics be given time to repent, Michael halted the killings.^[12]

In 812, Michael reopened negotiations with the Franks, and recognized Charlemagne as imperator and basileus ("emperor"), but not "Emperor of the Romans".^[a] In exchange for that recognition, Venice and Istria were returned to the Empire. Michael sent ambassadors to negotiate a marriage alliance between Michael's son Theophylact and a Frankish princess. They also brought a letter from Patriarch Nikephoros requesting papal arbitration on the issue of the Moechian controversy. Pope Leo III resolved the issue in favour of the Stoudites, who claimed that, as emperors were bound by canon law, Constantine VI's second marriage was illicit, which was the view of Empress Irene against Emperor Nikephoros. The Pope's judgment was treated as the formal closing of the affair.^[13][14][15]

There were also minor successes against the Arabs in the Anatolic Theme under its stratēgos Leo the Armenian, another figure exiled by Nikephoros and recalled by Michael. However, Michael dealt with the Bulgars poorly during his reign. In 812, Khan Krum besieged the frontier town of Develtos in Thrace, and Michael was too late to prevent its surrender. His soldiers mutinied, and people in western Thrace began to flee their homes. Some soldiers of the tagmata tried to proclaim the blinded sons of Constantine V as emperors, but Michael dismissed them in disgrace. The Bulgars nevertheless managed to capture almost all of the fortified towns on the Byzantine-Bulgarian border that were built and consolidated by Empress Irene and Emperors Constantine VI and Nikephoros in the previous decades. Michael was convinced by Nikephoros and Theodore to reject the peace terms offered by Krum, which involved the return of Christians who fled from Bulgarian territory, provoking the capture of Mesembria (Nesebar) by the Bulgars, the last border stronghold, executing all captives who refused to renounce Christianity. Michael's army prepared for a major engagement at Versinikia near Adrianople, but delayed his attack, leading to further discontent in the military. In June, he begun the attack but appeared hesitant; Leo the Armenian fled halfway through the battle, causing a rout. This prompted suspicion of treachery, however, Leo was acclaimed emperor with the support of his soldiers. Once he arrived in Constantinople, Michael was pressured to retire to a monastery. He was crowned by Patriarch Nikephoros on 12 July 813 ^[4][16][17]

With conspiracy in the air, Michael preempted events by abdicating on 11 July 813 in favour of Leo and becoming a monk (under the name Athanasios).^[18][4] His sons were castrated to end the dynasty and were relegated to monasteries,^[18] with one of them, Niketas (renamed Ignatios), eventually becoming Patriarch of Constantinople.^[19] Michael died on 11 January 844.^[20]

The numismatic record of Michael's reign begins after his son's coronation as co-emperor in 811, with new nomismata struck, bearing Michael on the obverse and Theophylact on the reverse. The miliarēsion, which had not been struck since the reign of Constantine VI (r. 780–797), was revived by Michael with a notable alteration. The imperial title basileis was expanded to basileis romaion ("emperors of the Romans"), seemingly in response to Pope Leo III's coronation of Charlemagne as emperor in 800.^[21]

The reigns of the iconoclast emperors Leo III the Isaurian (r. 717–741) and Constantine V (r. 741–775) were militarily successful and saw the abatement of the Arab and Bulgar threat. According to the iconodule Patriarch Nikephoros I of Constantinople, Isaurian propaganda ascribed both their military successes and longevity to their iconoclasm. The validity of iconoclasm was only confirmed by the military disasters under the iconodule emperors Michael and his predecessor Nikephoros I (r. 802–811) as well as the success of the iconoclast Leo V the Armenian (r. 813–820) against the Bulgars.^[22] Michael was in general a weak emperor whose policies were formed in mere reaction to outside pressures.^[23] Warren Treadgold describes him as "amiable to a fault, lacking in judgment and easily led", "dithering", seeming "to have done whatever he had been told most recently."^[24] He was also the last Byzantine emperor to be overthrown by the military, which is ironic given its increased strength in succeeding centuries.^[25]

In 813, Carolingian Emperor Charlemagne crowned his son Louis the Pious co-emperor in a manner resembling Michael's crowning of his own son, Theophylact, in 811. This was likely because of the Byzantine practice of inviting foreign ambassadors to witness state rituals. Accepting one such invitation, Hugh, Count of Tours, and Haito, Bishop of Basel, were present for Michael's crowning of his son, and so probably returned to the Frankish court with knowledge of Byzantine ceremonies.^[26]

By his wife Prokopia, Michael I had at least five children:

• Georgo, a daughter^[27]
• Theophylact, crowned co-emperor on Christmas 811, became a monk after 813.^[28]
• Niketas, later Patriarch Ignatios of Constantinople (c. 798 – 877)^[19]
• Staurakios, crowned co-emperor on Christmas 811, pre-deceased his father^[29]
• Theophano, a daughter^[30]
