By an unwise administration of this vast empire, Spain, in the course of time, killed the goose that laid the golden egg. The native Indians, enslaved and lashed to their work in Peruvian and Mexican silver mines, rapidly lost even their primitive civilization and died in alarming numbers. This in itself would not have weakened the monarchy greatly, but it appeared more serious when we remember that the high-handed and harassing regulations imposed by short-sighted or selfish officials had checked the growth of a healthy agricultural and industrial population in the colonies, and that the bulk of the silver was going to support the pride of grandees and to swell the fortunes of German speculators, rather than to fill the royal coffers. The taxes levied on trade with the colonies were so exorbitant that the commerce with America fell largely into the hands of English and Dutch smugglers. Under wise government the monopoly of the African trade-route might have proved extremely valuable, but Philip II, absorbed in other matters, allowed this, too, to slip from his fingers. While the Spanish monarchy was thus reaping little benefit from its world-wide colonial possessions, it was neglecting to encourage prosperity at home. Trade and manufacture had expanded enormously in the sixteenth century in the hands of the Jews and Moors. Woolen manufactures supported nearly a third of the population. The silk manufacture had become important. It is recorded that salt-works of the region about Santa Maria often sent out fifty shiploads at a time. These signs of growth soon gave way to signs of decay and depopulation. Chief among the causes of ruin were the taxes, increased enormously during the sixteenth century. Property taxes, said to have increased 30 per cent, ruined farmers, and the "alcabala," or tax on commodities bought and sold, was increased until merchants went out of business, and many an industrial establishment closed its doors rather than pay the taxes. Industry and commerce, already diseased, were almost completely killed by the expulsion of the Jews (1492) and of the Moors (1609), who had been respectively the bankers and the manufacturers of Spain. Spanish gold now went to the English and Dutch smugglers who supplied the peninsula with manufactures, and German bankers became the financiers of the realm.
