Banu Ghaniya

[3][4] Following the collapse of the Almoravid power at the hand of the Almohads in the 1140s, the Banu Ghaniya continued to govern the Balearic Islands as independent emirs until about 1203, with a brief interruption in the 1180s.

Later leaders (Ali ibn Ishaq and Yahya) made a determined attempt to reconquer the Maghreb (and in particular Ifriqiya), taking Bougie, Constantine and Algiers,[5] and conquering most of modern Tunisia[6] from about 1180 onwards.

[3] In Tunisia, Ali ibn Ishaq adhered to the Abbasid Caliphate and was formally appointed by Al-Mustadi with the title of "heir of the Almoravids".

In 1144 or 1145, Yahya was transferred from eastern al-Andalus to Seville in order to counter the rebellion of Ibn Qasi in the west.

[8][12] Eventually, faced with attacks by the Christian kingdoms to the north and the Almohad invasion, Yahya attempted to reach an agreement with his enemies to remain as lord of Jaén, but he was soon expelled from there too by Alfonso VII of León and Castile.

[8] Following the fall of the last Almoravid ruler in Marrakesh in 1147, the Banu Ghaniya maintained control of the Balearics and held off several Almohad attacks on the islands.

[5] The Banu Ghaniya undertook miltary campaigns against the Almohads in North Africa from November 1184 to 12378, in hopes of re-establishing Almoravid rule.
