He succeeded his father
Hammad ibn Buluggin in 1029. He named his brother Yusuf as governor of North Africa, and another brother, Ouighlan, governor of Hamza (modern day
Bouira). In 1038 he was attacked by Hammama, lord of
Fes but pushed him back after which Hammama requested peace and declared his submission to the Hammadids. Four years later, he signed a treaty of peace with the
Zirid Al-Mu'izz ibn Badis, who had moved against him from
Kairouan. In 1048, when al-Muizz declared himself subject of the
Abbasid caliph of Baghdad, Qaid confirmed his allegiance to the
Fatimid caliphs of Egypt, obtaining by caliph
Ma'ad al-Mustansir Billah the title of
Sharaf al-Dawla. He died in October 1054, and was succeeded by his son
Muhsin ibn Qaid. ==References==
