* The Kharijites were a group of early Muslims who rejected the authority of the Umayyad Caliphate. They established a number of independent kingdoms in the Maghreb during the 7th and 8th centuries, and their military prowess helped to spread Islamic rule throughout the region. However, they were eventually defeated by the Umayyads, and their influence waned.
* The Almoravids were a Berber group from the Sahara Desert. They embraced a strict form of Islam and embarked on a series of military conquests that brought much of the Maghreb under their control in the 11th century. They defeated various Berber tribes, the Christian kingdoms of Iberia, and even pushed into the Iberian Peninsula, where they played a significant role in the Reconquista. Their rule was marked by a period of stability and cultural flourishing, and they contributed to the spread of Islamic architecture and learning throughout the region.
While other Berber groups and rulers played important roles in the history of the Maghreb, the Kharijites and the Almoravids stand out for their significant contributions to the unification of the region under Muslim rule.
