Ahmad ibn Tulun
In ca. 877 the Abbasid regent al-Muwaffaq decided to appoint Amajur over Egypt, as its governor Ahmad ibn Tulun had been displaying signs of independence. Although Amajur was somewhat reluctant about the plan, the general Musa ibn Bugha was dispatched to enforce the decision and install him in the province. The expedition, however, stalled at Raqqa and came to an end when Musa's troops revolted against him, forcing him to return to Iraq; as a result, Ibn Tulun remained in control of Egypt.
