The beneficial effects of leniency upon the Moriscoes, as contrasted with the employment of violent measures, were soon disclosed. They conformed, with seeming alacrity, to the often vexatious regulations imposed upon their conduct. They wore the Spanish costume; they adopted, in all public transactions at least, the use of the Castilian language. Colleges were founded for their instruction by devout and enterprising prelates. Their children, male and female, were educated in the schools, and assumed the ecclesiastical habit of the various monastic orders within whose jurisdiction they were enrolled. From Morisco seminaries missionaries went forth to instruct and reconcile their doubting countrymen. In imitation of their patrons, they founded and supported religious brotherhoods. Their professions were apparently sincere; they began to perform their duties with scrupulous regularity; and it seemed as if at last the hitherto delusive hope of Moslem conversion was about to be realized. But the spirit of ferocious intolerance, ever predominant in the Spanish character, and which in the sixteenth century amounted to a frenzy, regarded with anything but complacency the indulgent consideration extended towards the unhappy objects of hereditary aversion. With this sentiment generally prevalent, fresh pretexts for encroachment were easily invented. In 1560 the assistance of the government was invoked by the Christians of Granada to restrain the purchase of slaves by the Moriscoes, who, it was stated, were in the habit of instructing their servants secretly in the doctrines of Islam and thereby multiplying the number of its adherents, to the scandal of the Church and the prejudice of the royal authority. No attempt was made to ascertain the truth or falsity of this accusation, and the Moriscoes were deprived, by royal decree, of the right of possessing slaves, a measure seriously affecting the rural and domestic economy of the entire population of Granada, which was dependent upon the cultivation of the soil by a multitude of negroes held by the Moorish farmers in servitude.
