The Imamate of Imam Sultan Muhammed Shah is witness to a glorious period in Ismaili history, as portrayed by the illustrious presentation of the Jubilees, where the followers weighed their Imam physically against gold, diamond and platinum respectively, and subsequently placed these in humble submission to the Imam.

After the death of the King, Imam Hasan Aly Shah continued to enjoy the good pleasure of the newly enthroned grandson, much to the chagrin of the other political bodies. After such envy turned into rising political tension and armed conflict, the Imam was forced to leave Iran for good and travelled through Afghanistan to Sind, Pakistan, and finally choosing to settle down in Bombay, India. In due course, Imam Hasan Aly Shah was conferred the title of His Highness by Queen Victoria of Britain.
Mowlana Imam Hasan Aly Shah was born in Mahalat, Iran, in 1805AD. He would succeed his father, who had been murdered by a group of fanatics, at the young age of thirteen years.

Imam Abyl Hasan Ali moved to Shahr-i Babak in Kirman, mainly to ensure the safety of the Ismaili pilgrims from the plundering tribesman who had thus far posed much difficulty to the pilgrims as they were on their way to the Anjudan and Mahallat regions where the Imam had previously resided. Sayed Fateh Ali Shah who had visited the Imam in Shahr-i Babak alludes to the Imam's location in northern iran ('sehentar deep') in one of his ginans.

Imam Nizar passed away in Kahek, his body buried in his palace, which served as a mausoleum also for other members of the Imam's family. (Sadik Ali, 1997).
The last Imam to live in Anjudan, Imam Khalilillahi Ali remained aloof from the political instability which prevailed throughout Iran at this time. During this time, Pir Naseer Mohammed was followed by Pir Agha Hashem in the line of Piratan. Sayyid Daood, an acclaimed vakil, was appointed by the Imam to govern the religious affairs in the jamats of India. The Imam was followed in succession by his son Sayyid Nizar Ali in 1585.
