كيف إنتهى العصر العباسي ؟
The political power of the caliphs largely ended with the rise of the Iranian Buyids and the Seljuq Turks, which each captured Baghdad in 945 and 1055 respectively. Although Abbasid leadership over the vast Islamic empire was gradually reduced to a ceremonial religious function, the dynasty retained control over its Mesopotamian domain. The Abbasids' period of cultural fruition ended in 1258 with the sack of Baghdad by the Mongols under Hulagu Khan. The Abbasid line of rulers, and Muslim culture in general, re-centred themselves in the Mamluk capital of Cairo in 1261. Though lacking in political power, the dynasty continued to claim religious authority until after the Ottoman conquest of Egypt in 1517.
