Tarasios of Constantinople
Tarasios of Constantinople was the Ecumenical Patriarch of Constantinople from 25 December 784 until his death on 25 February 806.
Background
Tarasios was born and raised in the city of Constantinople. A son of a high-ranking judge, Tarasios was related to important families, including that of the later Patriarch Photios I of Constantinople. He had an elder brother, Sisinnios, who was captured during the invasion of Calabria in 788–789.Tarasios had embarked on a career in the secular administration and had attained the rank of senator, eventually becoming imperial secretary to the Emperor Constantine VI and his mother, the Empress Irene of Athens. When Patriarch Paul IV of Constantinople retired to a monastery, he recommended the lay administrator Tarasios as his successor.
Since Tarasios exhibited both Iconodule sympathies and the willingness to follow imperial commands when they were not contrary to the faith, he was selected as Ecumenical Patriarch of Constantinople by Empress Irene in 784, even though he was a layman at the time. Nevertheless, like all educated Byzantines, he was well versed in theology, and the election of qualified laymen as bishops was not unheard of in the history of the Church.
He reluctantly accepted, on condition that church unity would be restored with Rome and the Oriental Patriarchs, and a council be called to address the iconoclast controversy. To make him eligible for the office of patriarch, Tarasios was duly ordained to the deaconate and then the priesthood, prior to his consecration as bishop.
Second Council of Nicaea

As a part of his policy of improving relations with Rome, he persuaded Empress Irene to write to Pope Adrian I, inviting him to send delegates to Constantinople for a new council, to repudiate heresy. The Pope agreed to send delegates, although he disapproved of the appointment of a layman to the patriarchate. The council convened in the Church of the Holy Apostles on 17 August 786. Mutinous troops burst into the church and dispersed the delegates. The shaken papal legates at once took ship for Rome. The mutinous troops were removed from the city, and the legates reassembled at Nicaea in September 787. The Patriarch served as acting chairman. The council, known as the Second Council of Nicaea, condemned Iconoclasm and formally approved the veneration of icons. The patriarch assumed a moderate policy towards former Iconoclasts, which incurred the opposition of Theodore the Studite and his partisans.
