Louis XIII, 1601-43, king of France (1610-43). He succeeded his father, Henry IV, under the regency of his mother, Marie de' Medici. He married Anne of Austria in 1615. Even after being declared of age in 1614, he was excluded from affairs of state by his domineering mother. In 1617 he caused the assassination of her minister Concino Concini, with the aid of his own favorite, Charles d'Albert, duc de Luynes, and Marie de' Medici was forced into retirement. He was reconciled to her in 1622 and entrusted (1624) the government to her protégé, Cardinal Richelieu. In 1630, urged by his mother to discharge Richelieu, he instead sent his mother again into exile. Melancholy and retiring by nature, Louis thenceforth gave full support to Richelieu and his successor, Cardinal Mazarin. Richelieu strengthened royal authority and centralized government control. Louis's reign was remarkable for the establishment of the French Academy and for the work of St. Francis de Sales and St. Vincent de Paul in religion, René Descartes in philosophy, and Pierre Corneille in literature.

(born Sept. 27, 1601, Fontainebleau, France—died May 14, 1643, Saint-Germain-en-Laye) King of France (1610–43). He was the son of Henry IV and Marie de Médicis. His mother was regent until 1614 but continued to govern until 1617; she arranged Louis's marriage to the Spanish Anne of Austria in 1615. Resentful of his mother's power, Louis exiled her, but Cardinal de Richelieu, her principal adviser, reconciled them in 1620. In 1624 Louis made Richelieu his principal minister, and the two cooperated closely to make France a leading European power, consolidating royal authority in France and fighting to break the dominant rule of the Spanish and Austrian Habsburgs in the Thirty Years' War. Pro-Spanish Catholic zealots led by Marie de Médicis appealed to Louis to reject Richelieu's policy of supporting the Protestant states, but Louis stood by his minister and his mother withdrew into exile. France declared war on Spain in 1635 and had won substantial victories by the time Richelieu died in 1642. Louis was succeeded by his son Louis XIV.
