What is "masmuda"

The Masmuda is a Berber tribal confederacy of Morocco and one of the largest in the Maghreb, along with the Zanata and the Sanhaja. They were composed of several sub-tribes: Berghouatas, Ghomaras (Ghomarids), Hintatas ( Hafsids), Tin Malel, Hergha, Genfisa, Seksiwa, Gedmiwa, Hezerdja, Urika, Guerouanes, Bni M'tir, Hezmira, Regraga, Haha les Banou Maghus, Gilawa and others. Today, the Masmuda confederacy largely corresponds to the speakers of the Shilha (Tachelhit) Berber variety, whereas other clans, such as Regraga and Doukkala, have adopted Arabic.
