Moulouya River
The "Banu Marin" (Marinids) were a semi-nomadic Zenata Berber tribe who in the 12th century were practicing transhumance in the region between Figuig and the Moulouya River in what is now eastern Morocco. Unlike many Zenata tribes in the region, they did not join the Almohads as they conquered the Maghrib. Later, their chief Muhyu did fight on the side of the Almohads and participated in the Battle of Alarcos in 1195, where he died of his wounds. Afterwards, leadership of the tribe passed on to Abd al-Haqq (Abd al-Haqq I).
