Victor Amadeus III of Sardinia
In 1763 his father granted him the Duchy of Chablais (the prince having been styled Duke of Chablais since birth), with the subsidiary lands of Cureggio, Trino, Dezan, Crescentino, Riva di Chieri, Well, Ghemme Pollenzo Tricerro, and Apertole Centallo. His brother, later Victor Amadeus III of Sardinia, created him Marquis of Ivrea on 19 June 1796. In 1764 Chablais also bought the fiefdom of Agliè, where the Ducal Palace of Agliè was situated, from his brother. Chablais also carried out improvements to the building under the direction of Ignatius Birago Borgaro.
