Pope Martin I (d. 656)
Pope Martin I (Latin: Martinus I; between 590 and 600 – 16 September 655), also known as Martin the Confessor, was the bishop of Rome from 21 July 649 to his death 16 September 655. He served as Pope Theodore I's ambassador to Constantinople and was elected to succeed him as pope. He was the only pope during the Eastern Roman domination of the papacy whose election was not approved by an imperial mandate from Constantinople. For his strong opposition to Monothelitism, Pope Martin I was arrested by Emperor Constans II, carried off to Constantinople, and ultimately banished to Cherson. He is considered a saint and martyr by the Catholic Church and the Eastern Orthodox Church.
