The tenth, eleventh, and twelfth centuries represent the epoch of the greatest fame and influence of the Spanish Jews. This period, coincident with the highest power and civilization of the Hispano-Arab empire, had, however, been preceded by two centuries of uninterrupted progress. The enlightened policy of the Western khalifs, from the accession of the Ommeyade dynasty, attracted to their capital the learned of every country and of every profession. Of these strangers, the Hebrews constituted the largest proportion of any one race, excepting the Arabs. The schools and academies they founded vied in educational opportunities and literary culture with the Moslem institutions of similar character whose reputation was unrivalled in the world. The interpretations of the Scriptures and the Talmud, as promulgated by the synagogues of Toledo and Cordova, were acknowledged everywhere as of the highest and most binding authority. A constant and profitable intercourse was maintained with their kinsmen of the Orient, which promoted an interchange of ideas, and was consequently of incalculable advantage to the mental development of both divisions of the race.

Encouraged by the influence which they wielded, and presuming upon the favor of a liberal and indulgent sovereign, the Jews of the Moorish empire formed an organization modelled after the institutions of their ancestors which could scarcely have been tolerated under a severe and jealous despotism. They elected as their king a prince of the house of Judah, who, while not openly invested with the insignia of royalty, received the homage and the tribute of his subjects. Under this potentate judges and priests were chosen, who exercised the functions performed centuries before in the days of the independence and renown of the Hebrew nation. The Moors countenanced, and even approved of, the establishment of this anomalous system. Its officials, despite their grandiloquent titles, were strictly subordinated to the authority of the khalifate. They were suffered,
