Muhammad-Shah was the last Seljuq amir of Kerman, from 1183 until 1186.
The son of Bahram-Shah, Muhammad-Shah succeeded his uncle Turan-Shah to the throne of Kerman in 1183. By the time of his ascension Kerman had been overrun by bands of Ghuzz Turks. Their devastation of the province had made the city of Bardasir virtually uninhabitable, so Muhammad-Shah made Bam his capital. By 1186, however, Muhammad-Shah been unable to handle the Ghuzz, and he decided to abandon Bam and departed from Kerman. The Ghuzz chief Malik Dinar quickly seized control of Kerman in his place.
Muhammad-Shah at first hoped to receive foreign assistance to reacquire Kerman, and traveled to Fars and Iraq requesting help. He also sought for aid from the Khwarezmshah Tekish. Eventually, however, he realized that he could get no assistance in recovering Kerman. He made his way to the Ghurid Empire and spent the remainder of his life in the service of the Ghurid sultans.
