Nicephorus I, Michael I, and the Patriarch Nicephorus (802-813).
Nicephorus I (802-11) was a tough ruler. He had to restore an economy ruined by Irene's foolishly lavish grants and to secure the military defences in the Balkans and Asia Minor. He was orthodox, but evidently not pro-monastic. When the moderate Patriarch Tarasius died in 806, the Studite monks saw an opportunity for one of their own persuasion. Theodore Studites was their obvious candidate. Nicephorus I however secured the appointment of another Nicephorus. He came from an iconophile family and, like Tarasius, was a layman at the time of his election though by no means divorced from ecclesiastical affairs. 44He had worked under Tarasius in the imperial secretariat and in 787 he went with him to the council of Nicaea as an imperial official. He subsequently led a retired life near the Bosphorus and then at the imperial command he took charge of a large poorhouse in Constantinople. After hesitation he accepted imperial nomination and on 5 April became a monk. On 9 and 10 April he was ordained deacon and presbyter and was enthroned in Hagia Sophia on Easter Day 12 April. At this period he seemed to fall in with imperial policy. Apparently bowing to the wishes of the Emperor, who was furious at the papal coronation of Charlemagne, he did not send the Pope his customary synodical announcing his election and setting out his profession of faith. He also had to call a synod to reinstate Joseph the priest who had conducted Constantine VI's second marriage. 45This enraged the monastic party and Theodore Studites' vociferous opposition brought him another period of exile. 46At this time Theodore regarded the Patriarch Nicephorus as the betrayer of high ecclesiastical principles and was markedly hostile towards him, contemptuously describing him as 'Caesar's steward'. 47
The Emperor Nicephorus I had shown no desire to reverse the moderate orthodox religious policy which had on the whole prevailed during Tarasius' patriarchate. But after his disastrous defeat and death in battle against the Bulgar Krum in 811 there were quick changes in policy varying from support for the extreme monastic party to the revival of iconoclasm. Nicephorus I's successor Michael I (811-13) was an ineffective ruler who did not continue the statesmanlike economic and military policies of his predecessor. The Studites were recalled from exile and their influence was reflected in Michael's religious outlook. The Patriarch Nicephorus was induced to reverse the reinstatement of the priest Joseph (812) 48and he stated moreover that his earlier action in 809 had been due to imperial pressure. 49This was in effect a victory for the Studites. Then the church authorities were urged to act against Manichaeans or Paulicians and other heretics. 50This was in contrast to the policy of Nicephorus; he had valued the fighting qualities of the Paulicians and had enrolled them in his army, promising them religious freedom. Relations with the papacy and the West also took a different turn. The Patriarch Nicephorus was now able to send his synodal letter to the Pope, Leo III, apologizing for the delay due to hindrance from 'the powers that be'. 51The western imperial coronation, which had so infuriated the Emperor Nicephorus, was accepted by Michael I. He tried to stem Carolingian advance into Byzantine Adriatic territory by recognizing Charlemagne's title, though conceding only 'Emperor and Basileus', not 'Emperor of the Romans' which was reserved for East Roman rulers. Later Byzantine emperors did not accept this concession to the West and liked to taunt the German rulers by deliberately calling them 'rex' and not 'imperator'. Subsequent Byzantine repudiation could not however root out Germanic assumption of imperial authority which, though differing from the Byzantine conception, was nevertheless to constitute a continuing challenge to the universal claims of Constantinople. As far as Michael I was concerned renewed links with Rome and Aachen and strong monastic support at home could not compensate for his unstatesmanlike rule. Apparently relying on foolish advice given him by Theodore Studites, Michael was crushingly defeated by the Bulgars at Versinicia (813). In the face of the menacing Bulgarian advance on Constantinople hostility to the iconodules grew. The military failures of the Byzantines seemed to reflect divine displeasure at their iconophile religious policy. The tomb of the great general Constantine V was besieged by iconoclasts in the capital and they called on the dead ruler to arise and help them (June 813). Shortly afterwards, with the support of the army, Leo the Armenian, commander of the Anatolicon theme, gained the throne (10 July 813).
