The experience of Abd-al-Mumen with treacherous vassals and daring impostors made him reluctant to leave his capital, constantly exposed to revolution, for the sake of confirming his power over the Moslem states of Spain. And, indeed, there seemed to be but little necessity for his personal appearance in Andalusia. In addition to the native auxiliaries there were now fifty thousand Almohade veterans in that country. His generals had demonstrated their ability for command on many fields of battle. The principal cities of the South--Cordova, Seville, Carmona, Granada, Malaga, Almeria, Badajoz--were garrisoned by his troops. His armies had as yet sustained no repulse; the most fertile districts furnished them with abundant subsistence; a considerable tribute was collected from the Jews and Mozarabes, who were compelled to pay liberally for privileges and protection which they did not enjoy; Alfonso VII., the most redoubtable enemy of the Moslems, had recently died, and the other Christian princes, doubtful of their strength, hesitated to confront the victorious Almohade squadrons. Although determined not to imperil his crown by a prolonged absence from his capital, Abd-al-Mumen paid a visit to Gibraltar, which he strongly fortified, and where he received the homage of the various officials of his recently acquired dominions. Almost simultaneously with the disappearance of the Almoravides a new champion of Hispano-Arab independence arose in the east of the Peninsula. Mohammed-Ibn-Saad, Prince of Valencia, attempted, but without success, to oppose the authority of the hated Africans. Routed before Granada, he organized another army in the Alpujarras and, reinforced by a body of Christians from Toledo, again tried the fortunes of war under the walls of Cordova. The bravery of the Andalusians availed little in the presence of the invincible veterans of Abd-al-Mumen. They were cut to pieces, and their leader, Ibn-Saad, escaping with difficulty, fled to Murcia.
