Kyros of Constantinople

Kyros of Constantinople (Ancient Greek: Κῦρος; died 8 January 712) was the Ecumenical Patriarch of Constantinople from 705 to 711. He is regarded as a saint in the Eastern Orthodox Church and Catholic Church, which had set his feast for 7 January in Catholic Church and 8 January (21) in Orthodox Church. Kyros was placed on the patriarchal throne in 705 by Emperor Justinian II, as a replacement for the deposed Patriarch Callinicus I of Constantinople. Soon after Justinian II's decline and eventual fall in December 711, Kyros was replaced by the new Emperor Philippicus with Patriarch John VI of Constantinople, who shared Philippicus' Monothelite sympathies.
