I think you’re referring to Savoy.
Savoy (French: Savoie, pronounced /savwa/; Franco-Provençal: Savouè; Italian: Savoia) is a region of western Europe that emerged, along with the free communes of Switzerland, following the collapse of the Frankish Kingdom of Burgundy. Installed by Rudolph III, King of Burgundy, officially in 1003, the House of Savoy maintained independence as counts (see County of Savoy, ca 1000 to 1416) and then dukes (see Duchy of Savoy, 1416 to 1714), until Savoia was linked with the Kingdom of Sardinia, which included Piemonte in north-western Italy. Savoy was largely absorbed into France in 1860, as part of the political agreement with Napoleon III that brought about the unification of Italy.
In modern France, Savoy was part of the Rhône-Alpes region. Articles about the départements of created following annexation by France are to be found as Savoie and Haute-Savoie. The modern separatist / regionalist movements are discussed in the “Annexation and Opposition” section in this article.
The traditional capital remains Chambéry (Chiamberì), on the rivers Leysse and Albane, hosting the castle of the House of Savoy and the Savoyard senate. The state included six districts:
Savoy proper (capital Chambéry)
Chablais (capital Thonon-les-Bains)
Faucigny (capital Bonneville)
Tarentaise (capital Moûtiers)
Maurienne (capital Saint-Jean-de-Maurienne)
Genevois (capital Annecy).

Savoy. This regio was ruled by counts and later duces of the house of Savoy. It was independent between 1000 and 1714.
