With Mohammed the Green vanished the good fortune of the Almohades. The princes of that house, who followed El Nazir in rapid succession, purchased their royal prerogatives at the expense of continual unhappiness and danger, and were finally driven from the throne. The empire of Morocco was then divided, and three new dynasties were established; that of Fez, of Tunis, and of Tremecen. These three powerful and rival sovereignties greatly multiplied the {110} conflicts, crimes, and atrocities, the narration of which alone constitutes the history of Africa. About this period some dissensions arose in Castile, which, together with the part assumed by the King of Aragon in the war of the Albigense in France, allowed the Moors time to breathe. The Moslems were still masters of the kingdoms of Valencia, Murcia, Grenada, and Andalusia, with part of Algarva and the Balearic Isles, which last, until that time, had continued to be but little known to the Christians of the Continent. These states were divided between several sovereigns, the principal of whom was Benhoud, a descendant of the ancient kings of Saragossa, a sagacious monarch and a great commander, who by his genius and courage had obtained dominion over all the southeastern part of Spain. Next to Benhoud in rank, the most important of these Mohammedan princes were the kings of Seville and Valentia. The barbarian who reigned at Majorca was a mere piratical chief, whose enmity was formidable only to the inhabitants of the neighbouring coast of Catalonia. Such was the condition of Moorish Spain, {111} when two young heroes seated themselves, nearly at the same time, on the thrones of the two principal Christian states; and, after having allayed the commotions created during the period of their minority, directed their concentrated efforts against the Mussulmans, A.D. 1224, Heg. 621. These princes, who were mutually desirous to emulate each other in fame, but were never rivals in interest, both consecrated their lives to the extirpation of the inflexible enemies of their native land. One of these sovereigns was Jacques I., king of Aragon (a son of the Peter of Aragon who distinguished himself on the field of Toloza), who united to the courage, grace, and energy of his father, a greater degree of genius and success than fell to the lot of that sovereign. The other was Ferdinand III., king of Castile and Leon, a discerning, courageous, and enterprising monarch, whom the Romish Church has numbered with its saints, and history ranks among its great men. This prince was the nephew of Blanche of Castile, queen of France, and cousin-german of St. Lewis,[8] whom he nearly resembled in his {112} piety, his bravery, and the wise laws he framed for the benefit of his subjects.
