Al-Mamun of Toledo
Yahya ibn Ismail al-Mamun was the second ruler the Berber Hawwara Dhunnunid dynasty who was king of the Taifa of Toledo between 1043 and 1075.Biography
Yahya ibn Ismail succeeded his father Ismaïl ibn Dhi 'l-Nun in 1043. In 1062 he promised his allegiance to king Ferdinand I of León and Castile a fact that did not prevent him from giving military support to his son-in-law Abd al-Aziz ibn Amir, king of the Taifa of Valencia, when the Castilian king laid siege to the city. When Ferdinand I saw himself forced to end the siege and remove his army, Al-Mamun agreed to a union with the Taifa of Valencia which was to form a part of the Toledo taifa until 1092. He died at Córdoba in 1075.
