Sous in the context of "Saadi Sultanate"

Beni Ḥassan (Arabic: بني حسان "sons of Ḥassān") is a Bedouin Arab tribe which inhabits Western Sahara, Mauritania, Morocco and Algeria. It is one of the four sub-tribes of the Banu Maqil who emigrated in the 11th century from South Arabia to the Maghreb with the Banu Hilal and Banu Sulaym Arab tribes. In the 13th century, they took the Sanhaja territories in the southwest of the Sahara. In Morocco, they first settled, alongside their Maqil relatives, in the area between Tadla and the Moulouya River. The Sous Almohad governor called upon them for help against a rebellion in the Sous, and they resettled in and around that region. They later moved to what is today Mauritania, and from the 16th century onwards, they managed to push back all black peoples southwards to the Senegal Valley river. The Beni Hassan and other warrior Arab tribes dominated the Sanhaja Berber tribes of the area after the Char Bouba war of the 17th century. As a result, Arabs became the dominant ethnic group in Western Sahara and Mauretania. The Bani Hassan dialect of Arabic became used in the region and is still spoken, in the form of Hassaniya Arabic. The hierarchy established by the Beni Hassan tribe gave Mauritania much of its sociological character. That ideology has led to oppression, discrimination and even enslavement of other groups in Mauritania.

The Lamtuna (Berber languages: Ilemteyen) are a nomadic Berber tribe belonging to the Iẓnagen / Sanhaja (Zenaga) confederation, who traditionally inhabited areas from Sous to Adrar Plateau. During the Almoravid period, many Lamtunas emigrated northwards. Currently, the Lemtuna Tribe is based in the South of Mauritania (Monguel and Agueilat). The chief of this Tribe is Mr. Limam Ould Teguedi (former Minister of Justice, former Minister of Culture and former Attorney General of Mauritania). Among notable families are the family of Ehl Aly Ibn Ibrahim, the family of Ehel Sidelemine, Ehl Abdawa, Ehl Mohamed El-Emine and Ehl Mohammed Ghali. Sahrawi Tajakant as well as Messouma tribes are of the most recognisable offshoots of the Lamtunas. They inhabit areas in Algeria, Morocco, Mauritania and Western Sahara. The Banu Ghaniya, the successors of this dynasty in Tripoli and the Nafusa Mountains and the governors of the Spanish Balearic Islands until about the middle of the 13th century, originated from this tribe as well.

One of the members of the Sanhaja confederation, the Lamtuna inhabited the areas of Adrar and Tagant. During the 11th century, the Lamtuna, Godala, and Masufa tribes were united under the Lamtuna leader, Abu Abdallah Muhammad ibn Tifat (Tarsina). After Tarsina's death his successor Yahya ibn Ibrahim, of the Godala tribe, married a member of the Urtantac family that governed the Lamtuna, expanding both his personal influence and that of the family. The Lamtuna sat at the top of the ruling class as well as holding positions in important administrative and military posts in the Almoravid dynasty. After Abdallah ibn Yasin's death in 1059 Almoravid leadership was assumed by the chief of the Lamtuna, Abu Bakr ibn Umar, who fought against rebels in Mauritania in 1060. His cousin, Yusuf ibn Tashfin, continued to lead the Almoravids in southern Morocco and it was under his leadership that most of the Maghreb and Al-Andalus was conquered.

Abū ʿAbd Allāh Muḥammad Ibn Tūmart (Arabic: أبو عبد الله محمد ابن تومرت, ca. 1080– August 1130) was a Muslim religious scholar, teacher and political leader, from the Sous in southern present-day Morocco. He founded and served as the spiritual and first military leader of the Almohad movement, a puritanical reform movement launched among the Masmuda Berbers of the Atlas Mountains. Ibn Tumart launched an open revolt against the ruling Almoravids during the 1120s. After his death his followers, the Almohads, went on to conquer much of North Africa and part of Spain. Although the Almohad movement itself was founded by Ibn Tumart, his disciple Abd al-Mu'min was the founder of the ruling dynasty.

Abu Abdallah Muhammad ibn Abd al-Rahman al-Qaim bi-Amr Allah, (Arabic: القائم بأمر الله السعدي) often shortened to Abu Abdallah al-Qa'im or Muhammad al-Qa'im, was the first political leader of the Saadi Dynasty of Morocco. He ruled the Sous and other parts of southern Morocco from 1510 to 1517, setting the stage for his sons to lead the dynasty to power over the rest of Morocco in the decades after his death.

The Shilha people (Berber languages: ⵉⵛⵍⵃⵉⵢⵏ, romanized: išelḥiyen, Arabic: الشلوح, romanized: aš-Chlūḥ), or Chleuh or Ichelhiyen, are a Berber ethnic group that Inhabit and are Indigenous to the Anti-Atlas, High Atlas and the Sous valley.
