In addition to the terrible drain upon the country from losses in war, the expulsion of the Jews and the Moors was productive of the direst results. In 1609 all the Moriscoes were ordered to depart from the Peninsula within three days. The penalty of death was declared against all who failed to obey, and against any Christians who should shelter the recalcitrant. The edict was obeyed, but it was a blow from which Spain never recovered. The Moriscoes were the back-bone of the industrial population, not only in trade and manufactures, but also in agriculture. The haughty and indolent Spaniards had willingly left what they considered degrading employment to their inferiors. The Moors had introduced into Spain the cultivation of sugar, cotton, rice and silk. In manufactures and commerce they had shown superiority to the Christian inhabitants, and many of their products were eagerly sought for by other countries. All these advantages were sacrificed to an insane desire for religious unity. The reigns of Philip III. and Philip IV. witnessed a fearful acceleration in the decline of Spain by the contests with the Dutch and with the German Protestants in the Thirty Years' War, the wars with France, and the rebellion of Portugal in 1640, which had been united to Spain by Philip II. The reign of Charles II. was still more unfortunate, and his death was the occasion of the war of the Spanish succession. Under Charles III. (1759-1788), a wise and enlightened prince, the second great revival of the country commenced, and trade and commerce began to show signs of returning activity. Previous to his accession to the throne, Spain appeared to be a corpse, over which the powers of Europe could contend at will. Suddenly men were astounded to see that country rise with renewed vigor to play once more an important part on the international stage. Commerce and agriculture were developed, native manufactures were encouraged in every way possible, and an attempt was made to remove all prejudices against trade, among the nobles. Meritorious as these reforms were, it would give a false impression to represent them as wholly successful. The regeneration of Spain was by no means accomplished, and many of the abuses which had been growing for centuries, survived the attempt to effect their annihilation. One of the chief causes of this failure was the corruption and ignorance of the lower officials; and a large portion of the population remained, to a great extent, sunk in sloth and superstition, in spite of all that was done in their behalf.
