Al 'Alī

The Al 'Ali were a Bedouin clan of the Banu Rabi'ah, a branch of the Tayy. In 1337 their grazing grounds reached Dumat al-Jandal, and they were vassals of the Mamluks.

Branches later migrated to the Gulf. From 1739 an Al Ali chiefdom ruled Persia's Shibkuh coast; kinsmen also settled at Umm al-Quwain, where the Al Mualla rulers claimed Tayyid descent. In the late 18th century the tribe moved from Siniyah island to the mainland, building a fort and defensive wall at Umm al-Quwain.
