The Almoravid dynasty was a Berber Muslim dynasty centered in the territory of present-day Morocco. It established an empire that stretched over the western Maghreb and Al-Andalus, starting in the 1050s and lasting until its fall to the Almohads in 1147.

A ribāṭ is an Arabic term, initially designating a small fortification built along a frontier during the first years of the Muslim conquest of the Maghreb to house military volunteers, called murabitun, and shortly after they also appeared along the Byzantine frontier, where they attracted converts from Greater Khorasan, an area that would become known as al-ʻAwāṣim in the ninth century CE.
