Al-Mansur ibn al-Nasir (Arabic: المنصور بن الناصر) (died 1104) was the sixth ruler of the Hammadids in Algeria (1088–1104).
[1] In 1090, he left the Kal'a (Beni Hammad Fort), the traditional capital of the Hammadids, to settle in Béjaïa (Bougie) with his troops and his court,[2] which he considered less accessible to the Nomads.
[2] His father had already prepared this transfer by transforming a fishing port into a city he calls An-Nasiriya but which was to assume the name of Bougie,[1] the name of a tribe that inhabited this region.
[2] Al-Mansur built public buildings, palaces, a water distribution network and gardens in Bejaia.
[3] The Kal'a was not completely abandoned by al-Mansur and he even embellished it with a number of palaces.
