Louis XIII (The Just) (1601-1643), King of France (1610-1643), was the son of Henry IV and Marie de Medici. He became king at the age of nine on his father's assassination in 1610, with his mother assuming full powers of regent. One of Marie de Medici's major objectives at that juncture was to bring France into an alliance with Spain and Austria. She decided, therefore, that Louis was to marry Anne of Austria, the daughter of the Spanish king, Philip III, and they were, in fact, married in 1615. The relationship between the young king and his mother, however, was often hostile, as was his relationship with Cardinal Richelieu, his wife Anne's principal advisor. Richelieu, nevertheless, became the most important member of the king's council, and was in large measure responsible of directing France's policy. This policy, which was often openly hostile to non-Catholic members of the community, brought Louis into unremitting conflict with the Protestants. Through Richelieu's influence, Huguenot strongholds were captured, Italy was invaded and France entered the Thirty Year's War (1618-1649) against Habsburg Spain. Despite several attempts to reduce his power, Richelieu continued to retain his ascendancy over the king until the cardinal's death in 1642. Louis and Anne had a child, the future Louis XIV, on September 5, 1638, the event celebrated by this medal. The medal, though dated 1638, was likely struck at a later date, perhaps about 1690 (see Jones). The church of Val-de-Grace, the facade of which is depicted on the reverse of the medal, is a French baroque church built in Paris between 1645 to1650 by Francois Mansart.
