Conditions similar to those prevailing in Africa occupied the attention and destroyed the efficiency of the Mussulmans of Spain. With every year, with the inauguration of each successive potentate of magnificent pretensions and insignificant following, factional hatred was intensified. The Christians, by cession, by purchase, by conquest, were rapidly acquiring the territory once embraced by the khalifate of Cordova, which had been the prize of Moslem valor and the seat of Moslem faith. The authority of the representative of the Almohades was confined to a narrow district which scarcely extended beyond the environs of Seville. The enemies of Islam pressed daily upon the shrunken confines of the rich and extensive domain conquered by the soldiers of Tarik and Musa, made illustrious by three centuries of military success and intellectual progress under the Ommeyades, and degraded by the African sultans to humiliating dependence on a barbarian monarchy. In the West, the rich provinces of Lusitania and the Algarves had been absorbed by Portugal. In the East, the steady progress of the King of Aragon portended the approaching extinction of the Mussulman power. The principality of Guadix had assumed the dignity of a kingdom under the first prince of the Alhamares, a dynasty eventually destined to revive the departed glories of Cordova in the new metropolis of Granada. That entire region of the Peninsula which was still subject to Moslem rule was distracted by the implacable feuds of aspirants to the disrupted empire of the Almohades. The impracticability of again uniting the discordant constituents of that empire was not understood, or even considered. The rival contestants sacrificed every consideration of patriotic and religious duty to the gratification of their revenge or the furtherance of their ambition. Their subjects beheld with apprehension and disgust the purchase of Christian aid against their brethren by the payment of extravagant subsidies and the surrender of the bulwarks of the frontier. They saw the resources wasted which, if properly employed, might have redeemed from infidel occupation vast tracts of territory whose fertility had once been the pride of the industrious people of Andalusia. They saw their own arms turned upon their neighbors, when the combined efforts of both would have sufficed, if not to successfully resist, at least to check the progress of the common foe. Three princes indiscriminately arrayed against each other occupied an unenviable prominence in this suicidal conflict. In the West, Yahya, the former Almohade sovereign, held Seville. In the East, his nephew Mohammed-al-Ahmar and the celebrated partisan Mohammed-Ibn-Hud contended for the possession of the provinces of Murcia and Granada. The latter, in the ignoble desire to satiate his vengeance, had secured from the Castilians temporary immunity from molestation by the daily payment of a thousand pieces of gold.
