The ruthless barbarity, the blind and reckless folly of this measure, was followed by an everlasting curse of barrenness, ignorance, and penury. The sudden removal of enormous amounts of portable wealth deranged every kind of trade. The circulation of counterfeit money impaired public confidence. In Valencia four hundred and fifty villages were abandoned. The absence of the most industrious and prosperous class of its inhabitants was apparent in every community of Castile. Catalonia lost three-quarters of its population. The districts of Aragon rendered desolate by Moorish expulsion have never been repeopled. Agricultural science and mechanical skill disappeared. The hatred and disdain entertained by the Spaniards for the conquered race had never permitted them to profit by the experience and ingenuity of the latter. Intercourse with a Moor brought moral and social contamination. Still less could the admission of inferiority, which the adoption of his methods implied, be tolerated by the haughty, the vainglorious, the impecunious hidalgo. The effects of the discouragement of all forms of art and industry consequent upon war and persecution had been felt long previous to the expulsion of the Moriscoes in every part of the Peninsula. For many years after the capture of Cordova by Ferdinand III., it was found necessary to bring provisions from the North, not only for the support of the army, but to rescue from famine the sparse and thriftless population of a province which under the Ommeyade khalifs maintained with ease the great capital, as well as twelve thousand villages and hamlets. The decline in the number of inhabitants under Spanish rule indicates the utter stagnation of trade and agriculture. In 1492 the population of Castile was six and three-quarter million; in 1700 there were in the entire kingdom of Spain but six million souls--such had been the significant retrogression in two hundred years. The combined revenues of the Spanish Crown at the close of the fifteenth century amounted to a sum equal to three hundred thousand dollars, about one-thousandth of the annual receipts of the imperial treasury at the death of Abd-al-Rahman III., seven hundred years before.
