Henry IV of France (1552 - 1619). Henry IV, also known by the epithet Good King Henry or Henry the Great, was King of Navarre from 1572 and King of France from 1589 to 1610. He was the first monarch of France from the House of Bourbon, a cadet branch of the Capetian dynasty. He was assassinated in 1610 by François Ravaillac, a fanatical Catholic, and was succeeded by his son Louis XIII. The son of Antoine de Bourbon, Duke of Vendôme and Jeanne d'Albret, the Queen of Navarre, Henry was baptised as a Catholic but raised in the Protestant faith by his mother. He inherited the throne of Navarre in 1572 on his mother's death. As a Huguenot, Henry was involved in the French Wars of Religion, barely escaping assassination in the St. Bartholomew's Day massacre. He later led Protestant forces against the royal army. Henry IV and his predecessor Henry III of France are both direct descendants of the Saint-King Louis IX. Henry III belonged to the House of Valois, descended from Philip III of France, elder son of Saint Louis; Henry IV belonged to the House of Bourbon, descended from Robert, Count of Clermont, younger son of Saint Louis. As Head of the House of Bourbon, Henry was first prince of the blood. Upon the death of his brother-in-law and distant cousin Henry III in 1589, Henry was called to the French succession by the Salic law. He initially kept the Protestant faith and had to fight against the Catholic League, which denied that he could wear France's crown as a Protestant. To obtain mastery over his kingdom, after four years of stalemate, he found it prudent to abjure the Calvinist faith. As a pragmatic politician, he displayed an unusual religious tolerance for the era. Notably, he promulgated the Edict of Nantes, which guaranteed religious liberties to Protestants, thereby effectively ending the Wars of Religion. Considered a usurper by some Catholics and a traitor by some Protestants, Henry became target of at least 12 assassination attempts. An unpopular king among his contemporaries, Henry gained more status after his death. He was admired for his repeated victories over his enemies and his conversion to Catholicism. The Good King Henry was remembered for his geniality and his great concern about the welfare of his subjects. An active ruler, he worked to regularise state finance, promote agriculture, eliminate corruption and encourage education. During his reign, the French colonization of the Americas truly began with the foundation of the colony of Acadia and its capital Port-Royal. He was celebrated in the popular song Vive le roi Henri and in Voltaire's Henriade. Henry de Bourbon was born in Pau, the capital of the joint Kingdom of Navarre with the sovereign principality of Béarn. His parents were Queen Joan III of Navarre and her consort, Antoine de Bourbon, Duke of Vendôme, King of Navarre. Although baptised as a Catholic, Henry was raised as a Protestant by his mother, who had declared Calvinism the religion of Navarre. As a teenager, Henry joined the Huguenot forces in the French Wars of Religion. On 9 June 1572, upon his mother's death, the 19-year-old became King of Navarre. At Queen Joan's death, it was arranged for Henry to marry Margaret of Valois, daughter of Henry II and Catherine de' Medici. The wedding took place in Paris on 18 August 1572 on the parvis of Notre Dame Cathedral. On 24 August, the St. Bartholomew's Day massacre began in Paris. Several thousand Protestants who had come to Paris for Henry's wedding were killed, as well as thousands more throughout the country in the days that followed. Henry narrowly escaped death thanks to the help of his wife and his promise to convert to Catholicism. He was forced to live at the court of France, but he escaped in early 1576. On 5 February of that year, he formally abjured Catholicism at Tours and rejoined the Protestant forces in the military conflict. He named his 16-year-old sister, Catherine de Bourbon, regent of Béarn. Catherine held the regency for nearly thirty years. Henry became heir presumptive to the French throne in 1584 upon the death of Francis, Duke of Anjou, brother and heir to the Catholic Henry III, who had succeeded Charles IX in 1574. Given that Henry of Navarre was the next senior agnatic descendant of King Louis IX, King Henry III had no choice but to recognise him as the legitimate successor. Salic law barred the king's sisters and all others who could claim descent through only the female line from inheriting.
