The Zaydi tribesmen in the northern highlands, particularly those of Hashid and Bakil, constantly resisted Turkish rule in Arabia.[2] Justifying their presence in Yemen as a triumph for Islam, the Ottomans accused the Zaydis of being infidels.[3] Hassan Pasha was appointed governor of Yemen, which enjoyed a period of relative peace from 1585 to 1597. Pupils of al-Mansur al-Qasim suggested that he claim the immamate and fight the Turks.
