The French invaded Piedmont, but were totally defeated at the siege of Turin by Victor Amadeus and Prince Eugene of Savoy (1706), and eventually driven from the country.
Raimond Balthazar Phelypeaux, seigneur du Verger, a member of the La Vrilliere branch, was sent as ambassador to Savoy in 1700, where he discovered the intrigues of the duke of Savoy, Victor Amadeus II., against France; and when war was declared he was kept a close prisoner by the duke (1703-1704).
In 1440 Aleman obtained the support of the emperor Sigismund and of the duke of Milan to his views, and proclaiming the deposition of Pope Eugenius IV., placed the tiara upon the head of Amadeus VIII., duke of Savoy (henceforward known as antipope Felix V.).

When Amadeus succeeded to the throne these were divided into the county of Savoy (his own territory), the princi pality of Piedmont ruled by his nephew Philip, prince of Achaea (a title acquired through his wife, Isabella of Villehardouin, heiress of Achaea and the Morea), and Vaud ruled by his brother Louis.
On the 25th of June 1439 the synod - which had already pronounced sentence of heresy on Eugenius IV., by reason of his obstinate disobedience to the assembly of the Church - formally deposed him; and, on the 5th of November, a rival pontiff was elected in the person of the ambitious Amadeus of Savoy, who now took the Felix V.
His only son, Victor Amadeus II.
In 1730 Victor Amadeus abdicated in favor of his son Charles Emmanuel III.
He sat in the Cortes Constituyentes of 1869 as a doctrinaire Conservative, combating all Radical and democratic reforms, and defending the exiled Bourbons; but he abstained from voting when the Cortes elected Amadeus king on the 16th of November 1870.
