List of Isma'ili imams

This is a list of the Imams as recognized by the different sub-sects of the Ismai'li sect of Shia Islam. Imams are considered members of the Bayt (Household) of Muhammad through his daughter Fatima.

Early Imams

All Isma'ili sects roughly share the first four Imams with the Zaydi Shia, and the first six Imams with the Twelver Shia. The Nizari and Musta'li are collectively also known as Fatimid Isma'ili, in contrast to the Sevener Isma'ili.

After Ali ibn Husayn Zayn al-Abidin, the Zaydis consider Zayd ibn Ali to be their next Imam rather than his older brother Muhammad al-Baqir who is considered the next Imam by the Isma'ili and Twelvers. After Ja'far al-Sadiq, the Twelvers consider Musa ibn Ja'far to be their next Imam, whereas Fatimid Isma'ilis consider his older brother Isma'il ibn Ja'far to be their next Imam, followed next by his son Muhammad ibn Isma'il. The Sevener Isma'ilis consider either Isma'il ibn Ja'far or his son Muhammad ibn Isma'il to be their final Imam and occulted Mahdi.

The Seveners propagated their faith from their bases in Syria through Da'iyyun. In 899, Abd Allah al-Mahdi Billah announced that he was the "Imam of the Time" being also the fourth direct descendant of Muhammad ibn Isma'il in the very same dynasty, and proclaimed his previous three descendant Da'is to have been "hidden Imams". This caused a split between his Sevener followers accepting his claim and the Qarmatian who continued to dispute his claim and considered Muhammad ibn Isma'il as the Imam in occultation. Abdallah al-Mahdi Billah eventually became the first Fatimid Caliph with his empire spanning Egypt and the eastern Maghreb. Sevener communities continued to exist in Eastern Arabia and Syria, and for a while in northern Iran but where it was gradually replaced by Fatimid Isma'ilis and other Shiʿi communities.

Fatimid

In the Fatimid and its successor Isma'ili traditions, the Imamate was held by the following. Each Imam listed is considered the son of the preceding Imam by mainstream accounts.

Abd Allah ibn Muhammad (Ahmad al-Wafi), died 829, "hidden Imam", son of Muhammad ibn Isma'il according to Fatimid Isma'ili tradition
Ahmad ibn Abd Allah (Muhammad at-Taqi), died 840, "hidden Imam"
Husayn ibn Ahmad (Abd Allah al-Radi), died 881, "hidden Imam"
Abd Allah al-Mahdi Billah, died 934, openly declares himself Imam, 1st Fatimid Caliph
Al-Qa'im bi-Amr Allah, died 946, 2nd Fatimid Caliph
Al-Mansur bi-Nasr Allah, died 953, 3rd Fatimid Caliph
Al-Mu'izz li-Din Allah, died 975, 4th Fatimid Caliph
Abu Mansur Nizar al-Aziz Billah, died 996, 5th Fatimid Caliph
Al-Hakim bi-Amr Allah, 6th Fatimid Caliph, disappeared 1021. The Druze believe in the divinity of all Imams and split off after al-Hakim's disappearance, believed by them to be the occultation of the Mahdi.
Al-Zahir li-I'zaz Din Allah, died 1036, 7th Fatimid Caliph
Al-Mustansir Billah, died 1094, 8th Fatimid Caliph.

After his death, the succession was disputed. The regent Malik al-Afdal placed Mustansir's younger son Al-Musta'li Billah on the throne. This was contested by the elder son Nizar al-Mustafa li-Din Allah, who was defeated and died in prison. This dispute resulted in the split into two branches, lasting to this day, the Nizari and the Musta'li.

Musta'li

The rival lines of succession of the Isma'ili imams resulting from the Musta'li–Nizari and Hafizi–Tayyibi schisms

The Musta'li recognized Imams:

Ahmad al-Musta'li Billah, died 1101, 9th Fatimid Caliph, son of al-Mustansir Billah
Al-Amir bi-Ahkam Allah, died 1130, 10th Fatimid Caliph, son of al-Musta'li Billah

Hafizi Ismaili Muslims claimed that al-Amir died without an heir and was succeeded as Caliph and Imam by his cousin al-Hafiz. The Musta'li split into the Hafizi, who accepted him and his successors as an Imam, and the Tayyibi, who believed that al-Amir's purported son At-Tayyib was the rightful Imam and had gone into occultation.

Tayyibi

The Tayyibi recognized Imam:

At-Tayyib Abu'l-Qasim, born 1130, disappeared in 1132, son of al-Amir bi-Ahkam Allah

The Tayyibi branch continues to this day, headed by a Da'i al-Mutlaq as vice-regent in the imam's occultation. The Tayibbi have broken into several branches over disputes as to which Da'i is the true vice-regent. The largest branch are the Dawoodi Bohra, and there are also the Sulaymani Bohra and Alavi Bohra.

Hafizi

The Hafizi recognized Imams:

Al-Hafiz li-Din Allah, died 1149, 11th Fatimid Caliph, cousin of al-Amir bi-Ahkam Allah
Al-Zafir bi-Amr Allah, died 1154, 12th Fatimid Caliph, son of al-Hafiz li-Din Allah
Al-Fa'iz bi-Nasr Allah, died 1160, 13th Fatimid Caliph, son of al-Zafir bi-Amr Allah
Al-Adid li-Din Allah, died 1171, son of Yusuf ibn al-Hafiz li-Din Allah, 14th Fatimid Caliph. The Fatimid Caliphate ended with Al-Adid's death.
Da'ud al-Hamid li-Allah, died 1207/8, son of al-Adid li-Din Allah. Died in prison under the Ayyubid dynasty, Al-Adil I.
Sulayman Badr al-Din, died 1248, son of Da'ud al-Hamid li-Allah. Died in prison under the Ayyubid dynasty, As-Salih Ayyub. The last Hafizi Imam.

The Hafizi Ismaili sect lived on until the 14th century in Egypt and Syria but had died out by the end of the 14th century.

Following the death of Shams al-Din Muhammad, the Nizari Isma'ili split into two groups: the Mu'mini Nizari (or, Muhammad-Shahi Nizari) who considered his elder son Ala al-Din Mu'min Shah to be the next Imam followed by his son Muhammad Shah, and the Qasimi Nizari (or, Qasim-Shahi Nizari) who consider his younger son Qasim Shah to be the next Imam
