I took Alexandria, Jerusalem and Antioch naturally in the process of securing the Miaphysite holy sites, and, after forming the Empire of Ethiopia, decided to try for the whole Pentarchy. Speaking of heresies, there are suddenly a lot of them in my current game, because I achieved something I've never seen anyone even attempt: healing the Great Schism, not as Catholicism or Orthodoxy, but as the Miaphysite Coptics of Nubia. We have an EU4 thread, but no CK2 thread? That's extra heretical!
