When the twenty–two year old Andronicos II (1282–1328) acceded to the throne of Byzantium, the empire was in a state of political, social, and ecclesiastical decline. This paper will consider the attempts of Patriarch Athanasios I to reverse this process of decay and to eliminate foreign religious elements from the capital of the Orthodox Byzantine empire. In 1261, the Byzantine empire had been restored to its capital, Constantinople, after fifty-seven years of Latin occupation. The city, however, had declined sadly from its former glory. The area of its effective hegemony was reduced to sections of western Anatolia and Greece, some islands in the Aegean, and Byzantine Thrace. Even this pitiful remnant was subject to the continuing assaults of the Turks, the pillaging of Catalan mercenaries turned hostile, the exploitation of Latin merchants, and threats of a Western military adventure to restore a Latin kingdom and Church of Constantinople.
