For seven generations this sultanate and Isma’ili imamate continued without any divisions. At the death of the seventh Imam, al-Mustansir bi’llah Mu’idd ibn Ali, his sons, Nizar and al-Musta’li, began to dispute over the caliphate and imamate. After long disputes and bloody battle al-Musta’li was victorious. He captured his brother Nizar and placed him in prison, where he died.
Following this dispute those who accepted the Fatimids divided into two groups: the Nizaris and the Musta’lis. The Nizaris are the followers of Hasan al-Sabbah, who was one of the close associates of al-Mustansir. After Nizar’s death, because of his support of Nizar, Hasan al-Sabbah was expelled from Egypt by al-Musta’li. He came to Persia and after a short while appeared in the Fort of Alamut near Qazwin. He conquered Alamut and several surrounding forts. There he established his rule and also began to invite people to the Isma’ili cause.
After the death of Hasan in 518/1124 Buzurg Umid Rudbari and after him his son, Kiya Muhammad, continued to rule following the methods and ways of Hasan al-Sabbah. After Kiya Muhammad, his son Hasan ’AlaDhikrihi’l-Salam, the fourth ruler of Alamut, changed the ways of Hasan al-Sabbah, who had been Nizari, and became Batini. Henceforth the Isma’ili forts continued as Batini. Four other rulers, Muhammad ibn Ala Dhikruhi’l-Salam, Jala al-Din Hasan, ’Ala’ al-Din, and Rukn al-Din Khurshah, became Sultan and Imam one after another until Hulagu, the Mongol conqueror, invaded Persia. He captured Isma’ili forts and put all the Isma’ilis to death, leveling their forts to the ground.
Centuries later, in 1255/1839, the Aqa Khan of Mahalat in Persia, who belonged to the Nizaris, rebelled against Muhammad Shah Qajar in Kerman, but he was defeated and fled to Bombay. There he propagated his Batini-Nizari cause which continues to this day. The Nizaris are today called the Aqa Khanids. The Musta’lis. The Musta’lis were the followers of al-Musta’li. Their imamate continued during Fatimid rule in Egypt until it was brought to an end in the year 567/1171. Shortly thereafter, the Bohra sect, following the same school, appeared in India and survives to this day.
The Druzes. The Druzes, who live in the Druze mountains in Syria (and also in Lebanon), were originally followers of the Fatimid caliphs. But as a result of the missionary activity of Nashtakin, the Druzes joined the Batini sect. The Druzes stop with the sixth Fatimid caliph al-Hakim bi’llah, whom others believe to have been killed, and claim that he is in occultation. He has ascended to heaven and will appear once again to the world. The Muqanna’ah. The Muqanna’ah were at first disciples of ’Ata’ al-Marwi known as Muqanna’, who according to historical sources was a follower of Abu Muslim of Khurasan. After the death of Abu Muslim, Muqanna’ claimed that Abu Muslim’s soul had become incarnated in him. Soon he claimed to be a prophet and later a divinity. Finally, in the year 162/777 he was surrounded in the fort of Kabash in Transoxiana. When he became certain that he would be captured and killed, he threw himself into a fire along with some of his disciples and burned to death. His followers soon adopted Isma’ilism and the ways of the Batinis.
