al-Rahman's education was conducted with some rigour. It was claimed that he had learned and known the local Mozarabic language. Accession to throne Emir Abdallah died at the age of 72. Despite four of his sons (Aban, Abd al Rahman, Muhammad and Ahmad) being alive at the time of his death, all of them were passed over for succession. Abdallah instead chose as his successor his grandson, Abd al-Rahman III (the son of his first son). This came as no surprise, since Abdallah had already demonstrated his affection for his grandson in many ways, namely by allowing him to live in his own tower (something he did not allow for any of his sons), and allowing him to sit on the throne on some festive occasions. Most importantly, Abdallah gave Abd al-Rahman his ring, the symbol of power, when Abdallah fell ill prior to his death. Abd al-Rahman succeeded Abdallah the day after his death, 16 October 912. Historiographers of the time, such as Al-Bayan al-Mughrib and the Crónica anónima de Abd al-Rahman III, state that his succession was "without incident". At the time, Abd al-Rahman was about 21 or 22 years old. He inherited an emirate on the verge of dissolution, his power extending not far beyond the vicinity of Córdoba. To the north, the Christian Kingdom of Asturias was continuing its program of Reconquista in the Douro valley. To the south in Ifriqiya, the Fatimids had created an independent caliphate that threatened to attract the allegiance of the Muslim population, who had suffered under the harsh rule of Abdullah. On the internal front the discontented Muwallad families (Muslims of Iberian origin) represented a constant danger for the Córdoban emir. The most powerful of the latter was Umar ibn Hafsun, who, from his impregnable fortress of Bobastro, controlled much of eastern Al-Andalus. From the very early stages of his reign, Abd al-Rahman showed a firm resolve to quash the rebels of al-Andalus, consolidate and centralise power, and re-establish internal order within the emirate. Within 10 days of taking the throne, he exhibited the head of a rebel leader in Cordoba. From this point on he led annual expeditions against the northern and southern tribes to maintain control over them. To accomplish his aims he introduced into the court the saqalibah, slaves of East European origin. The saqalibah represented a third ethnic group that could neutralise the endless strife between
