Biography

Life of Maria Theresa of Austria

The Pragmatic Sanction

The daughter of Emperor Charles VI, she was born in Vienna in 1717. Her father spent years securing the powers’ recognition of the Pragmatic Sanction of 1713, which allowed a woman to inherit. In 1736 she married Francis Stephen of Lorraine, subsequently Grand Duke of Tuscany.

The War of the Austrian Succession

On her father’s death in 1740, she inherited Austria, Bohemia and Hungary, but Prussia invaded Silesia, while Bavaria, France and Saxony disputed the inheritance. With Hungarian noble support she held out, although she lost Silesia. In 1745 her husband was elected emperor as Francis I. Her own sovereign titles were queen and archduchess; she was empress consort through her husband.

Reforms and family

She reorganised the administration, army and finances, and introduced compulsory schooling in 1774. The Seven Years’ War did not restore Silesia to her. From 1765 she ruled alongside her son Joseph II. She married her daughters into several reigning houses, including Marie Antoinette, Queen of France. She died in Vienna in 1780.
