The relationship between Navarre and the Franks was unusual.
Juana Of Navarre married Philippe IV of France and it was their children who became involved in the Tour Nestlé affair.
Louis X married Margaretha Of Burgundy who was found guilty of adultery. Nevertheless their daughter Juana II was allowed to marry Philippe d’Evereux and was accepted as Queen of Navarre.
Edward III of England was not the only one making claims on the Frankish throne. Charles II of Navarre, Philippe’s son, also made claims and intermittently entered treaties with Edward to make joint attacks on the Frankish homeland . Gaston de Foix was married to Agnes of Navarre, Charles’ sister, which made it difficult for Gaston to avoid involvment in the various intrigues.
