Abstract
The immigration of the Arab tribes now present in the south of Egypt especially the tribes of Bani Hilal, to the west of the Arab Land is a cause for the deterioration of bani Zen al-Sanhaji state.Its power was limited within the walls of al-Mahdiah city, and it became under the control of the Arab tribes specially the African cities suburabs. Some of the powerful people in Africa also fully controlled the cities they were ruling. This situation was the cause to control cites like Bni Maki in Qabis, Bani Khurasan in Tunisia.
