Reigned from 654 to 657. Born in Rome, Italy; died there. He was elected pontiff during the compulsory exile of Martin I, who would not submit to Byzantine direction in the matter of Monothelitism, and his election was subsequently approved by Martin. As pope he demanded a profession of faith from Emperor Constans II, a defender of Monothelitism; the emperor however answered with a request that the pope should enter into communion with the Patriarch of Constantinople. Eugene refused this invitation as there seemed no prospect of an acceptance of the Catholic doctrine in regard to the heresy. Feast, June 2,.
