of more ancient traditions of penitence. She experienced a mystical ecstasy that became profoundly influential on Spanish culture and art. Ignatius Loyola, founder of the Jesuit Order, was influential across the world in his stress on spiritual and mental excellence and contributed to a resurgence of learning across Europe. In 1625, a peak of Spanish prestige and power, the Count-Duke of Olivares established the Jesuit colegia imperial in Madrid to train Spanish nobles in the humanities and military arts. The Moriscos of southern Spain had been forcibly converted to Christianity in 1502, but under the rule of Charles I they had been able to obtain a degree of tolerance from their Christian rulers. They were allowed to practice their former custom, dress, and language, and religious laws were laxly enforced. (However, Charles also passed the Limpieza de sangre, a law that excluded those not of pure Old Christian, non-Jewish blood from public office.) Philip began to put back into place the restrictive laws of generations before and in 1568 the Moriscos rebelled (see Morisco Revolt). The revolt was only put down by Italian troops under Don John of Austria, and even then the Moriscos retreated to the highlands and were not defeated until 1570. The revolt was followed by a massive resettlement program in which 12,000 Christian peasants replaced the Moriscos. In 1609, on the advice of the Duke of Lerma, Philip III expelled the 300,000 Moriscos of Spain. The expulsion of the industrious Jews, Moors, and Moriscos did nothing to advance the Spanish economy. The small scattered groups of Moriscos lived largely by subsistence farming in marginal mountain areas or by unskilled laboring in a country that had very many underemployed hands. A council set up to investigate the matter in Castile found little effect, but in parts of Aragon and especially Valencia, where half the Moriscos had lived, and had made up a substantial minority of the population, the impact was certainly noticeable for the noblemen who had lost rents. Administration and bureaucracy The Spanish received a large influx of gold from the colonies in the New World as plunder when they were conquered, much of which Charles used to prosecute his wars in Europe. In the 1520s silver began to be extracted from the rich deposits at Guanajuato, but it was not until the 1540s, with the opening of the mines at Potosí and Zacatecas, that silver
