Louis was ten years old when the peace of Westphalia was concluded and the House of Habsburg, as a result of the Thirty Years War, lost its predominant position in Europe. It was inevitable that a man with his ambition should use so favourable a moment to gain for his own dynasty the honours which had formerly been held by the Habsburgs. In the year 1660 Louis had married Maria Theresa, daughter of the King of Spain. Soon afterward, his father-in-law, Philip IV, one of the half-witted Spanish Habsburgs, died. At once Louis claimed the Spanish Netherlands (Belgium) as part of his wife's dowry. Such an acquisition would have been disastrous to the peace of Europe, and would have threatened the safety of the Protestant states. Under the leadership of Jan de Witt, Raadpensionaris or Foreign Minister of the United Seven Netherlands, the first great international alliance, the Triple Alliance of Sweden, England and Holland, of the year 1661, was concluded. It did not last long. With money and fair promises Louis bought up both King Charles and the Swedish Estates. Holland was betrayed by her allies and was left to her own fate. In the year 1672 the French invaded the low countries. They marched to the heart of the country. For a second time the dikes were opened and the Royal Sun of France set amidst the mud of the Dutch marshes. The peace of Nimwegen which was concluded in 1678 settled nothing but merely anticipated another war. A second war of aggression from 1689 to 1697, ending with the Peace of Ryswick, also failed to give Louis that position in the affairs of Europe to which he aspired. His old enemy, Jan de Witt, had been murdered by the Dutch rabble, but his successor, William III (whom you met in the last chapter), had checkmated all efforts of Louis to make France the ruler of Europe. The great war for the Spanish succession, begun in the year 1701, immediately after the death of Charles II, the last of the Spanish Habsburgs, and ended in 1713 by the Peace of Utrecht, remained equally undecided, but it had ruined the treasury of Louis. On land the French king had been victorious, but the navies of England and Holland had spoiled all hope for an ultimate French victory; besides the long struggle had given birth to a new and fundamental principle of international politics, which thereafter made it impossible for one single nation to rule the whole of Europe or the whole of the world for any length of time.
