2. Queen Jeanne I (of Navarre), daughter of King Enrique I (III) and Blanche D'ARTOIS, was born circa 1271. She had the title 'Reina de Navarre'. She appeared in the census. She died on [Julian] 2 April 1305. She married Philippe IV ROI DE FRANCE.

As the greatest heiress of the age, she was much in demand as a marriage partner. On 30 November 1273, Edward I of England arranged with her father King Enrique that she would marry his second son Henry, then five, with his brother Alfonso, just a few days old at the time of the arrangement, as the 'substitute' in the case of Henry's demise. However, the sudden death of Jeanne's father in July 1274 put paid to the alliance between Navarre and England, and Jeanne was subsequently betrothed to 'one of the sons' of Philip III of France. She grew up with them at Vincennes, and married the future Philip IV on 16 August 1284, aged between eleven and thirteen.
[Edward II had three older brothers, John, Henry and Alfonso, who all died young, in 1271, 1274 and 1284 respectively.]

Jeanne and Philip evidently enjoyed a close relationship, and in 1294, Philip named her Regent of France in case he died before their sons came of age. Although Philip ruled Navarre in right of his wife, Jeanne herself governed her county of Champagne. In 1304, she founded the Coll¨¨ge de Navarre in Paris, one of the colleges of the university of Paris. It was suppressed at the time of the French Revolution.

I've seen several references to the fact that Queen Jeanne raised an army and led her troops against Henri III, Count of Bar (husband of Edward II's eldest sister Eleanor) when he invaded her lands, but I can't find any details. Allegedly, she also kept him prisoner. When this is meant to have happened, I don't know, but doesn't it seem highly unlikely that a woman would lead troops into battle - a high-born woman at that?

Jeanne/Juana, Queen of France, Queen of Navarre in her own right, Countess of Champagne, Brie and Bigorre, died on 2 or 4 April 1305, still in her early thirties, and was buried at the Couvent des Cordeliers in Paris. She was succeeded in Navarre by her eldest son, King Luis I, later Louis X of France, who was fifteen and a half - he and his brothers united the thrones of France and Navarre for a time.

King Philippe IV ROI DE FRANCE, son of Philippe III ROI DE FRANCE (1245-1285) and Isabel de ARAGON (1243-1271), was born circa 1268. He had the title 'Roi de France'. He appeared in the census. He died on [Julian] 29 November 1314. He and Jeanne I (of Navarre) had the following children:

3. Isabelle de France, daughter of King Philippe IV ROI DE FRANCE and Queen Jeanne I (of Navarre), was born between 1292 and 1295. She married Edward II KING OF ENGLAND.

Edward II KING OF ENGLAND of Caernarfon, son of Edward I KING OF ENGLAND (1239-1307) and Eleanor of Castile (1240-1290), was born on [Julian] 25 April 1284. He had the title 'King of England'. He died on [Julian] 21 September 1327. He and Isabelle de France had the following children:
