STEPHEN V., pope from 885 to 891, succeeded Adrian III., and was in turn succeeded by Formosus. In his dealings with Constantinople in the matter of Photius, as also in his relations with the young Slavonic church, he pursued the policy of Nicholas I. His pontificate was otherwise unimportant.

STEPHEN VI., pope from May 896 to July-August 897, succeeded Boniface VI., and was in turn followed by Romanus. He is remembered only in connexion with his conduct towards the remains of Formosus, his last predecessor but one (see Formosus). It excited a tumult, which ended in his imprisonment and his death by strangling.

STEPHEN VII. (February 929 to March 931) and STEPHEN VIII. (July 939 to October 942) were virtually nonentities, who held the pontificate during the so-called “pornocracy” of Theodora and Marozia (see Rome, vol. XX. p. 787-8).
