In the case of the Western Alps (excluding the part from the chain of Mont Blanc to the Simplon Pass, which followed the fortunes of the Valais), a prolonged struggle for control took place between the feudal lords of Savoy, the Dauphiné and Provence. In 1349 the Dauphiné fell to France, while in 1388 the county of Nice passed from Provence to the house of Savoy, which also then held Piedmont as well as other lands on the Italian side of the Alps. The struggle henceforth was limited to France and the house of Savoy, but little by little France succeeded in pushing back the house of Savoy across the Alps, forcing it to become a purely Italian power.
