Catherine de' Medici, queen of Henry II of France (born 1519)

Catherine de' Medici was an Italian Florentine noblewoman of the Medici family and Queen of France from 1547 to 1559 by marriage to King Henry II. She was the mother of French kings Francis II, Charles IX, and Henry III. She was a cousin of Pope Clement VII. The years during which her sons reigned have been called "the age of Catherine de' Medici" since she had extensive, albeit at times varying, influence on the political life of France.

Henry II was King of France from 1547 until his death in 1559. The second son of Francis I and Claude, Duchess of Brittany, he became Dauphin of France upon the death of his elder brother Francis in 1536.
