Abu Yusuf Ya'qub al-Mansur

Abu Yusuf Ya'qub al-Mansur (Arabic: ابو يوسف يعقوب المنصور) (c. 1160 –  January 23, 1199) (also known as Moulay Yacoub), was the third Almohad caliph, succeeding his father Abu Ya'qub Yusuf. The historian Abou Mohammed Salah ben Abd el-Halim of Grenada, writing in 1326, says in his Roudh el-Kartas (History of the Rulers of Morocco, French translation by A. Beaumier, 1860, PDF, p. 155  [1] ) "He was the son of a black woman." Yakub al-Mansur reigned from 1184 until 1199. He died in Marrakech, Morocco. During his reign, he undertook several major projects. He built the Koutoubia Mosque and the El Mansouria mosque in Marrakech and a kasbah in the southern part of its medina. He attempted to build what would have been the world's largest mosque in Rabat. However, construction on the mosque stopped after al-Mansur died. Only the beginnings of the mosque had been completed, including the Hassan Tower. Al-Mansur protected the philosopher Averroes and kept him as a favorite at court.
