Abu Zakariya Yahya al-Wattasi

Abu Zakariya Yahya ibn Ziyan al-Wattasi (died 1448) was a Wattasid strongman and vizier of Marinid Morocco. As governor of Salé, he seized power at Fez after Sultan Abu Sa'id Uthman III was assassinated in 1420, installed the infant Abd al-Haqq II as sultan and ruled as regent.

He kept power after the sultan came of age in 1436. When Henry the Navigator's Portuguese army besieged Tangier in 1437, Abu Zakariya starved it into surrender, securing a treaty promising the return of Ceuta. The victory won him widespread support. He ruled until his death, founding the Wattasid line of viziers and sultans.
