He was born in Turin to Victor Amadeus I, Duke of Savoy, and Christine of France. His maternal grandparents were Henry IV of France and his second wife Marie de' Medici. In 1638 at the death of his older brother Francis Hyacinth, Duke of Savoy, Charles Emmanuel succeeded to the duchy of Savoy at the age of 4. His mother governed in his place, and even after reaching adulthood in 1648, he invited her to continue to rule. Charles Emmanuel continued a life of pleasure, far away from the affairs of state. He became notorious for his persecution of the Vaudois culminating in the massacre of 1655, known as Piedmontese Easter. The massacre was so brutal that it prompted the English poetJohn Milton to write the sonnetOn the Late Massacre in Piedmont. Oliver Cromwell, Lord Protector, called for a general fast in England and proposed to send the British Navy if the massacre was not stopped while gathering funds for helping the Waldensians. Sir Samuel Morland was commissioned with that task. He later wrote The History of the Evangelical Churches of the Valleys of Piemont. The 1655 massacre was only the beginning of a series of conflicts, the Savoyard–Waldensian wars, that saw Waldensian rebels use guerrilla warfare tactics against ducal military campaigns to enforce Roman Catholicism upon the entire population. Only after the death of his mother in 1663, did he really assume power. He was not successful in gaining a passage to the sea at the expense of Genoa, and had difficulties in retaining the influence of his powerful neighbour France. But he greatly improved commerce and wealth in the Duchy, developing the port of Nice and building a road through the Alps towards France. He also reformed the army, which until then was mostly composed of mercenaries: he formed instead five Piedmontese regiments and recreated cavalry, as well as introducing uniforms. He also restored fortifications. He constructed many beautiful buildings in Turin, for instance the Palazzo Reale. He died on 12 June 1675, leaving his second wife as regent for his son. He is buried at Turin Cathedral.
Marriages and issue
Charles Emmanuel first met Marie Jeanne of Savoy in 1659 and fell in love with her. However, his mother disagreed with the pairing, and encouraged him to marry Françoise Madeleine d'Orléans, daughter of his maternal uncle Gaston, Duke of Orléans, the younger brother of his mother Christine Marie. They were married 3 April 1663. The couple had no issue. His mother died at the end of 1663, and his first wife died at the start of 1664. This left him free to get married on 20 May 1665 to Marie Jeanne of Savoy. They had one son:
