The union of no two countries could be less likely to prove advantageous or agreeable than that of the Netherlands and Spain. They were widely separated geographically, while in history, manners, and politics, they were utterly opposed to each other. Spain, which had but just assumed the form of a single state by the combination of all its kingdoms, with its haughty nobles descended from petty kings, and arrogating almost sovereign power within their domains, with its fierce enthusiasm for the Catholic religion, which, in the course of long warfare with the Saracens, had become the absorbing characteristic of a whole nation, with its sparse population scattered over a wide and stern country, with a military spirit which led nearly all classes to prefer poverty to the wealth attendant upon degrading pursuits of trade;--Spain, with her gloomy, martial, and exaggerated character, was the absolute contrast of the Netherlands. These provinces had been rarely combined into a whole, but there was natural affinity in their character, history, and position. There was life, movement, bustling activity every where. An energetic population swarmed in all the flourishing cities which dotted the surface of a contracted and highly cultivated country. Their ships were the carriers for the world;--their merchants, if invaded in their rights, engaged in vigorous warfare with their own funds and their own frigates; their fabrics were prized over the whole earth; their burghers possessed the wealth of princes, lived with royal luxury, and exercised vast political influence; their love of liberty was their predominant passion. Their religious ardor had not been fully awakened; but the events of the next generation were to prove that in no respect more than in the religious sentiment, were the two races opposed to each other. It was as certain that the Netherlanders would be fierce reformers as that the Spaniards would be uncompromising persecutors. Unhallowed was the union between nations thus utterly contrasted. Philip the Fair and Ferdinand had detested and quarrelled with each other from the beginning. The Spaniards and Flemings participated in the mutual antipathy, and hated each other cordially at first sight. The unscrupulous avarice of the Netherland nobles in Spain, their grasping and venal ambition, enraged and disgusted the haughty Spaniards. This international malignity furnishes one of the keys to a proper understanding of the great revolt in the next reign.
