Savoie in southeastern France corresponds to the provinces of La Savoie and of the Haute-Savoie (Upper Savoie). In the 4th century the term Sapaudia emerged which was translated as Savoie. In the 6th century the Franks invaded the region.
The annexation of Piémont in the 11th century and the occupation of Geneva and Montferrat considerably increased Savoie status as a state, although the Duchy underwent a period of decline from 1434 to 1553. After much erosion of its territorial boundaries it was finally returned to the sovereignty of France under the treaty of Turin in 1860.
