يزيد بن عبد الملك
Alexander's patriarchate occurred under several Umayyad caliphs, whose positions on the Copts varied greatly. These included Abd al-Malik, Al-Walid I, Sulayman ibn Abd al-Malik, Umar II, Yazid II, and Hisham ibn Abd al-Malik. This period included the Siege of Constantinople, which had a serious economic impact on the economy of Egypt. The failure at Constantinople, coupled with the financial strains brought about by the Al-Zubayr rebellion, made the Caliphs look to Egypt as the closest source of funds from which to prop themselves up economically.
