Patriarch of Alexandria

The Patriarch of Alexandria is the bishop of Alexandria, Egypt. Historically, this office has held the title of Pope, and did so before it was bestowed upon the Pope of Rome. Bestowing the title on Rome's patriarch did not strip it from Alexandria's. There are currently three claimants to this title: All three claimants acknowledge the same succession of church leaders up to about 460.
