Valencia taifa King born about 1050 and died 6 June 1085. His reign was developed in a relative peace that could occur due to the Alliance of the Valencian monarch with al-Muqtadir of Zaragoza.
Son of Abul Hassan Abdel Aziz, who was the founder of the amiri dynasty of Valencia, Abu Bakr was also a brother of the former matte of the taifa, Abd al-Malik Al - Muzaffar, who had been deposed by al - Ma'mumof Toledo in 1065. For ten years the city was ruled by which had been Secretary of the two previous Kings amiries, Ibn Raubas, who at the time had offered his services to al - Ma'mum and had ruled in his name. The death of al - Ma'mum in 1075, Abu Bakr revolted and imprisoned the vizier Ibn Raubas without any opposition from the Valencians. Acclaimed by the amiries, Abu Bakr did not take any promulgating title and was satisfied with the Vizier. Although the territories of their predecessors had been more or less extensive, Abu Bakr only reigned over the city of Valencia and its garden.
Unlike its predecessors, Abu Bakr noted for his fairness and good governance in their territories, following a neutral policy struggles between the different taifa. However, like his father, he is concerned about repair and fortify the walls of the city of Valencia. At the beginning of his reign he received an offer of Alliance from the writer Ibn Ammar, who was a vizier of the Regulus of Seville Muhammad Ibn Abbad al-Muctamid and, having betrayed, he took hold of Murcia and declared independence. Abu Bakr refused their offer, which unleashed the wrath of Ibn Ammar, reviled by his literary work the dynasty of Abu Bakr and urged the Valencians to they beat against his Lord, at the time maintained an intense literary activity aimed at undermining the King of Seville; Abu Bakr got a good payment, that a Jew would do with the originals of the works of Ibn Ammar and sent to al - Muctamid, as soon as he had them in his possession knowing them ordered the death of Ibn Ammar.
In 1076, Abu Bakr had to face the powerful al-Muqtadir of Zaragoza, who, after having conquered Denia, set their eyes on the Valencia taifa. The main obstacle to the monarch hudi was that Alfonso VI of Castile considered Valencia as reconquered area, so al - Muqtadir offered him a large amount of money in Exchange for which we are allowed to take over Valencia. Accepted treatment by the Spanish monarch, al - Muqtadir marched with his army for the conquest of the city; Abu Bakr received him personally and recognized its sovereignty, avoiding the military conquest of the city. Since then relations between Zaragoza and Valencia were excellent and were later made with the marriage of Ahmed, heir to the throne of Zaragoza, with the daughter of Abu Bakr (January of 1085).
Towards 1081 Abu Bakr received delegates from the villas at Ateca and Terrer, Calatayud, Daroca and Molina de Aragón, who requested protection of the amiri monarch against the Cid, which had conquered Alcocer and were encamped in the city with his troops. Abu Bakr sent an army of three thousand men to help Muslims who had asked him for help. Before the superiority of the Valencian army Cid sold Alcocer Ateca Muslims. The battle, which took place in Alcocer, has been considered as a part of the invention jugglery of cidiana legend by reputable historians as Menéndez Pidal, but Ambrosio Huici Miranda offers sufficient detail to prove that the battle actually took place and falls the fact the Alliance the taifas of Zaragoza and Valencia.
The death of Abu Bakr, shortly after the betrothal of his daughter with Ahmed of Zaragoza, his two sons intrigued to get power, until finally the taifa of Valencia passed to his son Utman al-Qadi, who could only reign for nine months until the King of Toledo, al - Qadi conquered the city, putting an end to the amiri dynasty of Valencia.
