Victor Amadeus II, duke of Savoy and afterward king of Sardinia, born May 14,1666, died Oct. 31, 1732. In 1675 he succeeded his father Charles Emanuel II., under the regency of his mother, against whose wishes he married in 1684 a niece of Louis XIV., who regarded Savoy as a vassal state. At that monarch's request he persecuted the Waldenses, and sent auxiliary troops to the French army in Flanders; but as Louis insisted upon his control of the whole army of Victor Amadeus, he joined in 1690 the Augsburg league against France. This contest, in which he displayed great valor, was nearly fatal to him; but he obtained in a treaty with Louis XIV. (1696) the restoration of important territories occupied by the French, and a large indemnity in money, and joined the French army with his troops. His defection contributed to the termination of the war of the Augsburg league, through the treaty of Ryswick of 1697. After the outbreak of the war of the Spanish succession, as Louis XIV. refused to purchase his alliance by a cession of territory, he again turned against him, and, defeating the French, who had overrun Savoy and Piedmont, with the aid of Prince Eugene, he recovered all his possessions, and in 1713, by the treaty of Utrecht, received additionally a part of the duchy of Milan and the kingdom of Sicily, and on Dec. 24 was crowned at Palermo. In 1720 he exchanged Sicily for the island of Sardinia, which Was then held by Austria, and assumed the title of king of Sardinia. On Sept. 3,1730, he abdicated in favor of his son Charles Emanuel III. A short time before he had secretly married his mistress, the countess of San Sebastiano, whom he made marchioness of Spigno. At her instigation he made in 1731 repeated but futile attempts to regain his throne.

He was imprisoned in September by order of his son, who was goaded on to this step by his courtiers and chiefly by the archbishop of Turin. He was dragged from his bed and confined for several days at the Rivoli palace, and then conveyed to Moncalieri, where he ended his life in captivity. His wife, who was permitted to join him, retired on his death to a convent in Turin, where she died in 1733.
