[Sidenote: Arab invasion of Spain.] Those were the circumstances of the Arab conquest of Spain. In that country the Arian Creed had been supplanted by the orthodox, and the customary persecutions had set in. From the time of the Emperor Hadrian, who had transported 50,000 Jewish families into Spain, that race had greatly increased, and, as might be expected, had received no mercy at the hands of the orthodox. Ninety thousand individuals had recently suffered compulsory baptism, and so had been brought under the atrocious Catholic law that whoever has been baptized shall be compelled to continue the observances of the Church. The Gothic monarchy was elective, and Roderic had succeeded to the throne, to the prejudice of the heirs of his predecessor. Though a very brave soldier, he was a luxurious and licentious man. It was the custom of the Goths to send their children to Toledo to be educated, and, under these circumstances, a young girl of extraordinary beauty, the daughter of Count Julian, governor of Ceuta in Africa, was residing there. King Roderic fell passionately in love with her, and, being unable to overcome her virtuous resolution by persuasion, resorted to violence. The girl found means to inform her father of what had occurred. "By the living God!" exclaimed the count, in a paroxysm of rage, "I will be revenged." But, dissembling his wrath, he crossed over into Spain, had an understanding with Oppas, the Archbishop of Toledo, and other disaffected ecclesiastics, and, under specious pretences, lulled the suspicions of Roderic, and brought his daughter away. And now he opened communications with the Emir Musa, prevailing upon him to attempt the conquest of the country, and offering that he himself would take the lead. The conditions were settled between them, and the consent of the khalif to the expedition obtained. [Sidenote: Its conquest.] Tarik, a lieutenant of the emir, was sent across the Straits with the van of the army. He landed on the rock called, in memory of his name, Gibraltar, April, A.D. 711. In the battle that ensued, a part of Roderic's troops, together with the Archbishop of Toledo, consummated their treasonable compact, and deserted to the Arabs; the rest were panic-stricken. In the rout, Roderic himself was drowned in the waters of the Guadalquivir.
