Alauddin Muhammad, or Muhammad III was born in 609/1213. He was succeeded by his father at the age of 9 years. The administration of the state affairs had been governed by his gifted mother for about six years, which was the first instance when a woman administered at Alamut.
The period of six years (618/1221 to 624/1227) was very peaceful in Alamut, during which time the Imam's mother seems to have deposed many incapable governors in Rudhbar and Kohistan. It seems that some governors and officers had misused their powers in that period. In 624/1227, Alauddin Muhammad took the power upon death of his mother at the age of 15 or 16 years, and dealt iron-handed with the persons misusing the powers. Most of them turned against him and went to live in Qazwin. In order to cover the story of their defalcations, they started to spread rumours against the Imam in bitter sarcasms. Some of them went on to propagate that the brain of Alauddin Muhammad had been affected few months before 624/1227 when a physician operated him, causing waste of excess blood. The oppositions were however surmounted very soon.
A cursory glance of the contemporary rules indicates that the Abbasid caliph Nasir had died in 622/1225, and was succeeded by Zahir (d. 623/1226), Mustansir (d. 640/1242) and Mustasim (d. 656/1258), the last of the dynasty. Jalaluddin Khwarazmshah (617-628/1220-1231) was however absolutely ruling in Central Asia.
