Thirty Years War: The Franco-Swedish Period

France entered openly into the war in 1635. Oxenstierna, the Swedish chancellor, anxious to preserve Sweden's hold in Germany, supported Richelieu. The final stage of the Thirty Years War began. The war now occupied most of Europe, with fighting in the Low Countries, where the United Provinces and France opposed Spain; in Italy, where France and Spain struggled for power; in France; in Germany; in the Iberian peninsula, where Portugal revolted against, and France attacked, Spain; and in the North, where Denmark opposed Sweden.

The Austrian forces went into France and achieved some success, but this was temporary. For the most part this period of the war was disastrous for the empire. Bernhard of Saxe-Weimar and the Swedish general, Baner, were victorious in Germany. In 1636 Baner won a notable victory at Wittstock. Bernhard conducted a series of brilliant campaigns, culminating in the capture of Breisach (1638). Bernhard died in 1639, Baner in 1641. Meanwhile, Emperor Ferdinand II was succeeded by Ferdinand III (1637). In 1642 Richelieu died; his successor, Cardinal Mazarin, continued the established French policy. Germany was exhausted.

Peace negotiations were begun before 1640, but the intricate diplomacy proceeded slowly and haltingly. Meanwhile, the empire was reduced by the armies of the Swedish Torstensson, Louis II de Condé, and Turenne. Torstensson defeated the imperialists at Breitenfeld (1642), defeated Gallas after going north to subdue Danish opposition, then won a climactic victory over Hatzfeldt at Jankau (1645). Meanwhile, Condé had destroyed the flower of the Spanish infantry at Rocroi (1643); in 1645 he and Turenne (after a severe defeat) were victorious near Nördlingen. Austria had been stripped of all conquests and her enemies were at the very door of Vienna. Austria's strongest ally, Bavaria, was overrun. The Swede Wrangel and the Frenchman Turenne were carrying on a successful campaign when the long-delayed peace was obtained (see Westphalia, Peace of).
