Stephen II of Constantinople
Stephen II of Constantinople was the Ecumenical Patriarch of Constantinople from 29 June 925 to 18 July 928.
He appears to have been appointed to the post by Emperor Romanos I Lekapenos after the death of Nicholas I of Constantinople as a stop-gap until Romanos I's own son, Theophylact, was old enough to assume the post. Steven Runciman calls him a "deliberate nonentity". He is a saint, commemorated on 18 July.
