The accession of al-Mu'ayyad Shaykh to the sultanate in 815 AH

In 815 AH Shaykh al-Mahmudi took the sultanate, was given the title al-Mu'ayyad, and was called Abu Nasr. This came after the deposition of al-Nasir Faraj, the sultanate and deposition of the caliph al-Musta'in, and the killing of al-Nasir Faraj. This is what the "Shadharat al-Dhahab" relates. ¹

The source arranges the events this way: deposition, then killing, then al-Mu'ayyad took the sultanate. The data does not give the place of the coronation or the details of the oath of allegiance, which need an additional source.

815 AH, with a Gregorian equivalent (around 1412 CE) that is derived. ¹
