We do not know much about Muhammad’s successors except their names. He appears to have been succeeded by his son Sulaimān and he was in turn succeeded by his son, ‘Isā Jāshū. The latter’s title of Jāshū “naval soldier”, might say something about the ruling society of Old Hormoz. Muhammad Deramku himself had managed to conquer Mūghestān and Mināb by the help of Omani Jashu soldiers, thus establishing the supremacy of naval officers and seamen in a kingdom that was essentially a thalassocracy, with most of its territory consisting of water.
