Ignatius III David
Jerusalem's Coptic Bishop 
Pope Cyril III of Alexandria used the increasing military and political power of Egypt over Jerusalem to appoint a Coptic Orthodox bishop of that church, which until then had been the prerogative of the Patriarch of Antioch. This angered Patriarch Ignatius III David, who retaliated by attempting unsuccessfully to fill the vacancy of Abuna or metropolitan for the Ethiopian Orthodox Church. This was a very rare incident between the two churches as in general their relationship is one of the strongest between any two churches.
