Treaty of Vienna (1738)

By the terms of the treaty, Stanisław Leszczyński renounced his claim on the Polish throne and recognized Augustus III, Duke of Saxony.

[1] As compensation he received instead the duchies of Lorraine and Bar, which were to pass to his daughter, Maria, the wife of King Louis XV of France upon his death.

Francis Stephen, who was the Duke of Lorraine, was indemnified with the vacant throne of the Grand Duchy of Tuscany, the last Medici having died in 1737.

In another provision of the treaty, the kingdoms of Naples and Sicily were ceded by Austria to Duke Charles of Parma and Piacenza, the younger son of King Philip V of Spain.

Charles, in turn, had to cede Parma to Austria, and to give up his claims to the throne of Tuscany in favor of Francis Stephen.
