As Africa, distracted by the long war of the Almoravides and the Almohades, was unable to offer any opposition to the progress of the Christians in Spain, these last, availing themselves of this condition of affairs, continued to extend their conquests in Andalusia. If the Spanish princes had been less disunited, and had acted in concert against the infidels, they would have been able { 99} at this period to deprive the Mussulmans of their entire dominions in the Peninsula. But these ever-contending princes had no sooner taken a Moorish city than they began to dispute among themselves about its possession.
The newly-created kingdom of Portugal, established by the military powers of Alphonso, was soon at war with that of Leon.[5] Aragon and Castile, after many bloody quarrels, united in a league against Navarre. Sancho VIII., the sovereign of that little state, was forced to resort to Africa for assistance, and implore the aid of the Almohades. But they, being but recently established on the throne of Morocco, were still employed in exterminating the dismembered fragments of the party of the Almoravides, and could not, in spite of their eager desire to do so, establish any claim to their assumed rights in Spain. Nevertheless, two kings of the race of the Almohades, both named Joseph, passed the Mediterranean more than once with numerous armies. The one was successfully opposed by the Portuguese, and did not survive his final defeat; the other was more fortunate, and succeeded in vanquishing the Castilians, but { 100} was soon after obliged to accept a truce and return in haste to Morocco, to which new disturbances recalled him, A.D. 1195, Heg. 591.
But these useless victories, these ill-sustained efforts, did not permanently disable either the Mussulmans or the Christians. On both sides, the vanquished parties soon re-entered the field, in utter neglect of the treaties into which they might ever so recently have entered. The sovereigns of Morocco, though regarded as the kings of Andalusia, nevertheless possessed only a precarious authority in that country, which was always disputed when they were absent, and acknowledged only when necessity forced the Mussulman inhabitants to have recourse to their protection.
