In 1524, following Ismail I's death, the Al-Mughamis resumed effective control.[3] Twelve years later, during the Ottoman–Safavid War of 1532–1555, the ruler of Basra, Rashid ibn Mughamis, acknowledged the Ottoman sultan Suleiman the Magnificent (r. 1520–1566) as his suzerain, who in turn confirmed him as governor of the city.[1] Though Basra submitted to the Ottomans, the Ottoman hold over Basra was initially tenuous.[2] This changed in 1546, when an Ottoman garrison was installed in the city after a Moshasha uprising.[2][6]
