He was born to Qatadah ibn Idris and a woman from the Anizah tribe.
According to Islamic sources, including Abu Shamah, al-Dhahabi, and Ibn Kathir, Qatadah died in July of 1220.
Historians mention that Hasan killed his father, brother, and uncle in order to gain control the Emirate.
Hasan was then dethroned somewhere in April or May of 1222 by al-Mas'ud Yusuf, the Ayyubid Emir of Yemen.
A Shi'ite, Hasan was buried in the mashhad of Musa al-Kazim.
