The Patriarchate of Alexandria is the office and jurisdiction of the bishop of Alexandria in Egypt, referred to since 531 as Patriarch of Alexandria. It originated from Mark the Evangelist and developed until the Council of Chalcedon in 451 when it split into parallel Chalcedonian and Miaphysite traditions, which then competed for the position for several decades before permanently parting ways in 536:
