 At the end of the 14th century, another piece of Provence along the Italian border, including Nice and the lower Alps, was detached from Provence and attached to the lands of the Duke of Savoy.The lower Alps were re-attached to France after the Treaty of Utrecht in 1713, but Nice did not return to France until 1860, during the reign of Napoleon III.The administrative region of Provence-Alpes-Cote d'Azur was created in 1982.
