The crowning misfortune was the revolt of the Netherlands, the richest provinces of the whole empire. Some of the wealthiest cities of Europe were situated in the Netherlands. Bruges had once been a great city, and in 1566 was still able to buy nearly $2,000,000 worth of wool to feed its looms; but as a commercial and financial center, the Flemish city of Antwerp had taken first place. In 1566 it was said that 300 ships and as many wagons arrived daily with rich cargoes to be bought and sold by the thousand commercial houses of Antwerp. Antwerp was the heart through which the money of Europe flowed. Through the bankers of Antwerp a French king might borrow money of a Turkish pasha. Yet Antwerp was only the greatest among the many cities of the Netherlands. Charles V, king of Spain during the first half of the sixteenth century, had found in the Netherlands his richest source of income, and had wisely done all in his power to preserve their prosperity. As we shall see in Chapter III, the governors appointed by King Philip II in the second half of the sixteenth century lost the love of the people by the harsh measures against the Protestants, and ruined commerce and industry by imposing taxes of 5 and 10 per cent on every sale of land or goods. In 1566 the Netherlands rose in revolt, and after many bloody battles, the northern or Dutch provinces succeeded in breaking away from Spanish rule. Spain had not only lost the little Dutch provinces; Flanders was ruined: its fields lay waste, its weavers had emigrated to England, its commerce to Amsterdam. Commercial supremacy never returned to Antwerp after the "Spanish Fury" of 1576. Moreover, during the war Dutch sailors had captured most of the former possessions of Portugal, and English sea-power, beginning in mere piratical attacks on Spanish treasure-fleets, had become firmly established. The finest part of North America was claimed by the English and French. Of her world empire, Spain retained only Central and South America (except Brazil), Mexico, California, Florida, most of the West Indies, and in the East the Philippine Islands and part of Borneo. [Sidenote: Dutch Sea Power] The Dutch, driven to sea by the limited resources of their narrow strip of coastland, had begun their maritime career as fishermen "exchanging tons of herring for tons of gold." In the sixteenth century they had built up a considerable carrying trade, bringing cloth, tar, timber, and grain to Spain and France, and distributing to the Baltic countries the wines and liquors and other products of southwestern Europe, in addition to wares from the Portuguese East Indies.
