Although William the Silent was assassinated by an agent of Spain (1584), and Antwerp was captured from the Protestants in 1585, the ability and genius of Farnese did not avail to make further headway against the United Provinces; but Philip II, stubborn to the end, positively refused to recognize Dutch independence. In 1609 Philip III of Spain consented to a twelve years' truce with the States-General of The Hague. In the Thirty Years' War (1618-1648) the Dutch and Spaniards again became embroiled, and the freedom of the republic was not recognized officially by Spain till the general peace of Westphalia in 1648. [Footnote: See below, p. 229.] The seven provinces, which had waged such long war with Spain, constituted, by mutual agreement, a confederacy, each preserving a distinct local government and administration, but all subject to a general parliament--the States-General--and to a stadtholder, or governor-general, an office which subsequently became hereditary in the Orange family. Between the States-General and the stadtholder, a constitutional conflict was carried on throughout the greater part of the seventeenth century--the former, supported by well-to-do burghers, favoring a greater measure of political democracy, the latter, upheld by aristocratically minded nobles, laboring for the development of monarchical institutions under the Orange family. [Sidenote: Natural Opposition of England and France to the Policies of Philip II] Not only his efforts in the Netherlands but many other projects of Philip II were frustrated by remarkable parallel developments in the two national monarchies of England and France. Both these countries were naturally jealous opposition and fearful of an undue expansion of Spain, which might upset the balance of power. Both states, from their geographical locations, would normally be inimical to Philip II: England would desire, from her island position, to destroy the monopoly which Spain claimed of the carrying trade of the seas; France, still encircled by Habsburg possessions in Spain, Italy, and the Netherlands, would adhere to her traditional policy of allying herself with every foe of the Spanish king. Then, too, the papal authority had been rejected in England and seriously questioned in France: Philip's crusading zeal made him the champion of the Church in those countries. For ecclesiastical as well as for economic and political purposes it seemed necessary to the Spanish king that he should bring France and England under his direct influence. On their side, patriotic French and English resented such foreign interest in their domestic affairs, and the eventual failure of Philip registered a wonderful growth of national feeling among the peoples who victoriously contended against him. The beginnings of the real modern greatness of France and England date from their struggle with Philip II. [Sidenote: Philip II and Mary Tudor]
