al-Qasim ibn Hammud al-Ma'mun

al-Qasim ibn Hammud ibn Maymun al-Idrisi, brother of Ali ibn Hammud al-Nasir; the two stood by Sulayman ibn al-Hakam al-Musta'in when the Berbers set him up as caliph in al-Andalus and served him well, al-Qasim receiving Algeciras — after Ali's death he took the caliphate as al-Ma'mun, contested by his nephew Yahya ibn Ali who prevailed over him, one of the last Hammudid caliphs of Cordoba.
