The softness of the climate, together with the effects of wealth and luxury, gradually enfeebled these conquerors, creating vices from which they had been previously free, and depriving {34} them of the warlike qualities to which alone they had been indebted for their success. Of the kings who succeeded Euric, some were Arians and others Catholics, who abandoned their authority to the control of bishops, and occupied a throne shaken to its centre by internal disturbances. Roderick, the last of these Gothic sovereigns, polluted the throne by his vices; and both history and tradition accuse him of the basest crimes. Indeed, in the instance of nearly all these tyrants, their vices either directly occasioned, or were made the pretext of their final ruin. The fact is well established, that Count Julian and his brother Oppas, archbishop of Toledo, both of them distinguished and influential men, favoured the irruption of the Moors into Spain. Tarik, one of the most renowned captains of his time,[10] was sent into Spain by Moussa. He had at first but few troops; but he was not by this prevented from defeating the large army that, by command of Roderick, the last Gothic king, opposed his course. Subsequently, having received re-enforcements {35} from Africa, Tarik vanquished Roderick himself at the battle of Xeres, where that unfortunate monarch perished during the general flight in which the conflict terminated, A.D. 714, Heg. 96. After this battle, the Mohammedan general, profiting by his victory, penetrated into Estremadura, Andalusia, and the two Castiles, and took possession of the city of Toledo. Being soon after joined by Moussa, whose jealousy of the glory his lieutenant was so rapidly acquiring prompted him to hasten to his side, these two remarkable commanders, dividing their troops into several corps, achieved, in a few months, the conquest of the whole of Spain. It should be observed, that these Moors, whom several historians have represented as bloodthirsty barbarians, did not deprive the people whom they had subjugated either of their faith, their churches, or the administrators of their laws. They exacted from the Spaniards only the tribute they had been accustomed to pay their kings. One cannot but question the existence of the ferocity that is ascribed to them, when it is remembered that the greater part of the Spanish cities submitted to the invaders {36} without making the least attempt at resistance; that the Christians readily united themselves with the Moors; that the inhabitants of Toledo desired to assume the name of _Musarabs_; and that Queen Egilona, the widow of Roderick, the last of the Gothic sovereigns, publicly espoused, with the united consent of the two nations, Abdelazis the son of Moussa.
