Paul Palaiologos Tagaris (c. 1330 – after 1394) was a Byzantine Greek monk, a swindler, and an impostor. A scion of the Tagaris family, Paul also claimed a—somewhat dubious—connection with the Palaiologos dynasty that ruled the Byzantine Empire at the time. Married as a teenager, he left his wife and became a monk, but soon his fraudulent practices embroiled him in scandal. Fleeing Constantinople, he travelled widely, from Palestine to Persia and Georgia and eventually, via Ukraine and Hungary, to Italy, Latin Greece, Cyprus and France. During his long and tumultuous career, Paul was appointed an Orthodox bishop, sold ordinations to ecclesiastical offices, pretended to be the Orthodox Patriarch of Jerusalem, switched from Greek Orthodoxy to Roman Catholicism and back again, supported both the See of Rome and the Avignon anti-popes in the Western Schism, and managed to be named Latin Patriarch of Constantinople. In the end, his deceptions unmasked, he returned to Constantinople, where he confessed his sins before a synod in 1394.
