The Peace of Nimeguen was followed by a period of ten years in which no extensive war broke out. They were, however, far from being years of political quiet. Louis XIV. was as intent upon pushing on his frontiers to the eastward in peace as in war, and grasped in quick succession fragments of territory which had not been given him by the peace. Claiming this and that in virtue of ancient feudal ties; this and that other as implicitly surrendered by the treaty, because dependent upon something else that had been explicitly surrendered; purchasing at one time, using bare force in other cases, and backing up all the so-called peaceful methods of obtaining his asserted rights by the presence of armed power, he carried on this process of extension between 1679 and 1682. The aggression most startling to Europe, and above all to the German Empire, was the seizure of the then imperial city of Strasburg on the 30th of September, 1681; and on the same day Casale, in Italy, was sold to him by the Duke of Mantua, showing that his ambitions were directed that way as well as to the north and east. Both of these were positions of great strategic importance, threatening, the one Germany, the other Italy, in case of war. The excitement throughout Europe was very great; in every direction Louis, serenely trusting to his power, was making new enemies and alienating former friends. The king of Sweden, directly insulted, and injured in his duchy of Deux-Ponts, turned against him, as did the Italian States; and the Pope himself sided with the enemies of a king who was already showing his zeal for the conversion of the Protestants, and was preparing for the revocation of the Edict of Nantes. But the discontent, though deep and general, had to be organized and directed; the spirit necessary to give it form and final effective expression was found again in Holland, in William of Orange. Time, however, was needed to mature the work. "No one yet armed himself; but every one talked, wrote, agitated, from Stockholm to Madrid.... The war of the pen preceded by many years the war of the sword; incessant appeals were made to European opinion by indefatigable publicists; under all forms was diffused the terror of the New Universal Monarchy," which was seeking to take the place once filled by the House of Austria. It was known that Louis sought to make himself or his son emperor of Germany. But complications of different kinds, private interests, lack of money, all combined to delay action. The United Provinces, despite William's wishes, were yet unwilling to act again as banker for a coalition, and the emperor was so threatened on his eastern frontier by the rebel Hungarians and the Turks that he dared not risk a western war.
