Hasan ibn Qatadah
Ḥasan ibn Qatādah ibn Idrīs al-Ḥasanī was the Emir of Mecca from 1220 to 1222.
He assumed the Emirate after the death of his father Qatadah ibn Idris. According to most sources, including Abu Shamah, al-Dhahabi, and Ibn Kathir, Qatadah died in Jumada I 617 AH. Al-Mundhiri writes that he died in late Jumada II 617 AH, while Ibn al-Athir writes that he died in Jumada II 618 AH. Historians mention that Hasan killed his father, brother, and uncle in order to gain control the Emirate.
Hasan was dethroned in Rabi al-Awwal 619 AH by al-Mas'ud Yusuf, the Ayyubid Emir of Yemen. He fled to Damascus, then to Baghdad, where he died in 623 AH. A Shi'ite, Hasan was buried in the mashhad of Musa al-Kazim.
