In page John II of France:

"

He took as his wife Bonne of Bohemia and fathered 11 children in eleven years. Due to his close relationship with his favourite Charles de la Cerda, partisans of Charles II of Navarre derided the king for "having no other God than him".[1] La Cerda was given various honours and appointed to the high position of connetable when John became king; he accompanied the king on all his official journeys to the provinces. La Cerda's rise at court excited the jealousy of the French barons, several of whom stabbed him to death in 1354. La Cerda's fate paralleled that of Edward II of England's Piers Gaveston and John II of Castile's Álvaro de Luna; the position of a royal favourite was a dangerous one. John's grief on La Cerda's death was overt and public.[citation needed]
