The Spanish Jews continued in this state of degradation until Egica's death. When his son Witiga followed him to the grave, the last hours of this empire were evidently at hand. The Jews of Africa, who at various times had emigrated thither from Spain, and their unlucky co-religionists of the Peninsula, made common cause with the Mahometan conqueror, Tarik, who brought over from Africa into Andalusia an army eager for the fray. After the battle of Xeres (July, 711), and the death of Roderic, the last of the Visigothic kings, the victorious Arabs pushed onward, and were everywhere supported by the Jews. In every city that they conquered the Moslem generals were able to leave but a small garrison of their own troops, as they had need of every man for the subjection of the country; they therefore confided them to the safe-keeping of the Jews. In this manner the Jews, who but lately had been serfs, now became the masters of the towns of Cordova, Granada, Malaga, and many others. When Tarik appeared before the capital, Toledo, he found it occupied by a small garrison only, the nobles and clergy having found safety in flight. While the Christians were in church, praying for the safety of their country and religion, the Jews flung open the gates to the victorious Arabs (Palm-Sunday, 712), receiving them with acclamations, and thus avenged themselves for the many miseries which had befallen them in the course of a century since the time of Reccared and Sisebut. The capital also was entrusted by Tarik to the custody of the Jews, while he pushed on in pursuit of the cowardly Visigoths, who had sought safety in flight, for the purpose of recovering from them the treasure which they had carried off. Finally, when Muza Ibn-Nosair, the Governor of Africa, brought a second army into Spain and conquered other cities, he also delivered them into the custody of the Jews. It was under these favorable conditions that the Spanish Jews came under the rule of the Mahometans, and like their co-religionists in Babylonia and Persia, they were esteemed the allies of their rulers. They were kindly treated, obtained religious liberty, of which they had so long been deprived, were permitted to exercise jurisdiction over their co-religionists, and were obliged, like the conquered Christians, to pay only a poll-tax (Dsimma). Thus were they received into that great alliance, which, to a certain extent, united all the Jews of the Islamite empire into one commonwealth.
