Mandylion
The situation changed however when the admiral Romanos Lekapenos assumed power as a co-emperor with three of his rather useless sons and Constantine VII, thus ending the internal problems with the government. Meanwhile, the Bulgar problem more or less solved itself with the death of Simeon in 927, so Byzantine general John Kourkouas was able to campaign aggressively against the Saracens from 923 to about 950. Armenia was consolidated within the Empire whilst Melitene, which had been a ruined emirate since the 9th century, was annexed at last. In 941 John Kourkouas was forced to turn his army north to fight off the invasion of Igor I of Kiev, but he was able to return to lay siege to Edessa—no Byzantine army had reached as far since the days of Heraclius. In the end the city was able to maintain its freedom when Al-Muttaqi agreed to give up a precious Christian relic: the "Image of Edessa".
