Idrisid dynasty
Since the earliest form of Zaydism was Jaroudiah, many of the first Zaidi states were supporters of its position, such as those of the Iranian Alavids of Mazandaran Province and the Buyid dynasty of Gilan Province and the Arab dynasties of the Banu Ukhaidhir of al-Yamama (modern Saudi Arabia) and the Rassids of Yemen. The Idrisid dynasty in the western Maghreb were another Arab Zaydi dynasty, ruling 788–985.
