Biography

Life of Ferdinand III of the Holy Roman Empire

King and general

The son of Ferdinand II and Maria Anna of Bavaria, he was born in Graz in 1608. He was crowned King of Hungary (1625) and Bohemia (1627). After Wallenstein’s death, he assumed imperial command and, with his cousin the Cardinal-Infante Ferdinand, defeated the Swedes at Nördlingen in 1634.

Emperor of war and peace

Elected King of the Romans in 1636, he succeeded his father in 1637, amid war against Sweden and France. Defeats and the exhaustion of his territories led him to negotiate at Münster and Osnabrück. The Peace of Westphalia (1648) recognised the German princes’ territorial sovereignty, toleration of Calvinism and the independence of the United Provinces and the Swiss Confederation.

Reconstruction and succession

In his hereditary lands he maintained the restoration of Catholicism and reorganised the standing army. An amateur composer, he supported court music. His eldest son, Ferdinand IV, died in 1654; on his death in Vienna in 1657, his son Leopold I succeeded him.
