THE Dutch Revolt lasted longer than any other uprising in modern European history—from the iconoclastic fury in August 1566 to the Peace of Munster in January 1648; and it involved more continuous fighting than any other war of modern times—from April 1572 to April 1607 (with only six months' cease-fire in 1577) and from April 1621 to June 1647. Its economic, social, and political costs were enormous. The longevity of the revolt becomes even more remarkable when one remembers that the two combatants were far from equal. The areas in revolt against Spain were small in size, in natural resources, and in population—especially in the first few years. In 1574 only about twenty towns, with a combined population of 75,000, remained faithful to William of Orange; Amsterdam, the largest town in Holland, stayed loyal to the king until 1578. Against the ‘rebels’ Philip II could draw on the resources of Spain, Spanish America, Spanish Italy and, of course, the Spanish Netherlands. Although by the seventeenth century the odds had narrowed somewhat—by then there were seven ‘rebel’ provinces with a combined population of over one million—Spain could still call on vastly superior resources of men and money. There were a number of occasions in the course of the war when Spain seemed to stand on the threshold of success. In 1575, for example, the con-quest of the islands of Duiveland and Schouwen in South Holland divided the rebel heartland in two and appeared to presage the collapse of the revolt. A decade later, in 1585, Antwerp was re-captured against all predictions, leaving Holland and Zealand dispirited and prepared to discuss surrender. As late as 1625, with the reconquest of Breda in Brabant and Bahia in Brazil, Spain's final victory seemed near. But total success never came. Spain never regained the seven northern provinces of the Netherlands and by 1648 Philip IV counted himself lucky to have retained the ten southern ones.
