Episcopate and Contributions
Photius governed the metropolis of Kiev and All Russia for some twenty-three years under Grand Prince Vasily I of Moscow. Sources record that he worked to rebuild the Church's material standing and to restore ecclesiastical discipline after the disruptions that preceded his arrival.
Beyond administration, he is credited with literary and canonical works, including a treatise on the selection and installation of bishops dated to 1423, and with efforts to suppress the Strigolniki movement, a dissenting current active in the Rus' lands during his episcopate.
