The oldest possessions of the line of Savoy were the counties of Maurienne (the upper valley of the River Arc), Savoy (the district between Arc, Isère, and the middle course of the Rhone), and also Belley, with Bugey as its chief town.
Henceforth the history of Savoy is in general the same as that of the Kingdom of Sardinia (q.v.).
During the French Revolution Savoy was occupied by the French, and by the Treaty of Nice in 1796 was surrendered to France together with Nice.
