Dynasties claiming Abbasid descent

Centuries after the Abbasids fall, several dynasties have claimed descent from them, as "claiming kinship relation with Muhammad", that is, claiming an affiliation to the 'People of the House' or the status of a sayyid or sharif, has arguably been the most widespread way in Muslim societies of supporting one's moral or material objectives with genealogical credentials." Such claims of continuity with Muhammad or his Hashemite kin such as the Abbasids foster a sense of "political viability" for a candidate dynasty, with the intention of "serving an internal audience" (or in other words, gaining legitimacy in the view of the masses). The Wadai Empire which ruled parts of modern-day Chad and Sudan also claimed Abbasid descent, alongside the Khairpur and Bahawalpur states in Pakistan and the Khanate of Bastak.

A common trope among Abbasid claimant dynasties is that they are descended from Abbasid princes of Baghdad, "dispersed" by the Mongol invasion in 1258 CE. These surviving princes would leave Baghdad for a safe haven not controlled by the Mongols, assimilate to their new societies, and their descendants would grow to establish their own dynasties with their Abbasid 'credentials' centuries later. This is highlighted by the origin myth of the Bastak khanate which relates that in 656 AH/1258 CE, the year of the fall of Baghdad, and following the sack of the city, a few surviving members of the Abbasid dynastic family led by the eldest amongst them, Ismail II son of Hamza son of Ahmed son of Mohamed migrated to Southern Iran, in the village of Khonj and later to Bastak where their khanate was established in the 17th century CE.

Meanwhile, the Wadai Empire related a similar origin story, claiming descent from a man by the name of Salih ibn Abdullah ibn Abbas, whose father Abdullah was an Abbasid prince who fled Baghdad for Hijaz upon the Mongol invasion. He had a son named Salih who would grow to become an "able jurist" and a "very devout man". The Muslim ulama on pilgrimage in Mecca met him and, impressed by his knowledge, invited him to return with him to Sennar. Seeing the population's deviation from Islam, he "pushed further" until he found the Abu Sinun mountain in Wadai where he converted the local people to Islam and taught them its rules, after which they made him sultan, thus laying the foundations of the Wadai Empire.

With regards to the Bastak khanate, Shaikh Mohamed Khan Bastaki was the first Abbasid ruler of Bastak to hold the title of "Khan" after the local people accepted him as a ruler, meaning "ruler" or "king", a title which was reportedly bestowed upon him by Karim Khan Zand. The title then became that of all the subsequent Abbasid rulers of Bastak and Jahangiriyeh, and also collectively refers in plural form, i.e., "Khans", to the descendants of Shaikh Mohamed Khan Bastaki. The last Abbasid ruler of Bastak and Jahangiriyeh was Mohamed A'zam Khan Baniabbassian son of Mohamed Reza Khan "Satvat al-Mamalek" Baniabbasi. He authored the book Tarikh-e Jahangiriyeh va Baniabbassian-e Bastak (1960), in which is recounted the history of the region and the Abbasid family that ruled it. Mohamed A'zam Khan Baniabbassian died in 1967, regarded as the end of the Abbasid reign in Bastak.
