As far west as the Maghrib, two Berber (Amazigh) dynasties that had emerged in the aftermath of the collapse of the Umayyad caliphate of Cordoba – the Almoravids (1040–1147), who were Abbasid vassals, and their autonomous Almohad successors (1121–1269) who claimed the caliphate for themselves...
The Almoravids, who acknowledged the spiritual authority of the Abbasid caliphate in Baghdad, founded their capital at Marrakech and by 1082 had extended their control along the Mediterranean coast beyond present-day Algiers to the edge of the Kabylia region.
But, as was the rule throughout the history of al-Andalus, the Almoravid Berbers accepted Arab cultural patterns and Arabic as the language of administration and culture.
En outre, bien que les Almoravides aient parlé le berbère, l'arabe restait la langue officielle. [Furthermore, although the Almoravids spoke Berber, Arabic remained the official language.]
