It seems that it was difficult to establish a clear definition of the tribes

that settled the Sahara in ancient times and formed the first nucleus of the Almoravid state. This is due to the scarcity of information and the time difference between writing and research time. Sources indicate that the number is about seventy tribes, including the historian Ibn Abi Zar'at. DAKALA. Masufah Musratah. and Taklata. Mendasa Bani Ziad. Beni Castell. Bani Msefir Bani Dakhir. Lamthouna and Lamta.

They are tribes that are included in the desert region from Nol of Lamta westward to the Kairouan tribe to the east and black Africa to the south and to the Berber to the north. However, the historian Hassan al-Wazzan (Lion of Africa) is the definer of the border of most extreme south of Berber, . The longitudinal identification in which Ibn Abi Zarath mentioned the field of Sanhaja in the desert from Nol of Lamta to the west to Kairouan in the east is a field that combines all the Sunnajah. But Ibn Khaldun divided it into two parts: the Zirids and the Hammadites who are in the Middle East and the other part. They are masked settlers in the arid desert to the south. Their area stretches from the surrounding sea to Ghadames east of Tripoli and Barqa. Ibn Khaldun took this identification from Ibn Abi Zer. Three months to four riding on camels and longer ones from west to east and up to seven months. The western limit remains the most accurate (Atlantic) Nurlama, which is the subject of this episode of memory.
