Père Anselme states that Isabelle was born in 1292 but does not cite the primary source on which he bases this date. The chronology of the births of Philippe IV’s children is tight and would fit better if Isabelle was born in 1291. Edward I King of England appointed “Amadeum comitem Sabaudiæ consanguineum nostrum” as proxy for the marriages between “nos et Margaretam sororem...regis Franciæ...ac inter Edwardum filium nostrum et Isabellam...regis Franciæ filiam” by charter dated 12 May 1299. The betrothal contract between “Ed. filz du roi d´Angleterre” and “Isabel fille du roi de France” is dated 20 May 1303. The Annales Londonienses record the marriage "apud Boloniam…in festo Conversionis Sancti Pauli" in 1308 of "rex Edwardus" and "Isabellam filiam regis Franciæ Philippi". The Continuatio of the Chronicle of Guillaume de Nangis records the marriage in Jan 1308 "apud Boloniam supra mare" of "Eduardus Angliæ rex" and "filiam unicam regis Franciæ Philippi...Isabellam". The Chronicle of Geoffrey le Baker of Swinbrook records the marriage “apud Boloniam...V Kal Feb” of “rex Edwardus” and “Isabellam filiam...regis Francie”.
She was crowned Queen of England with her husband [23/25] Feb 1308. The Chronicle of Geoffrey le Baker of Swinbrook records the return of the couple to England 5 Feb and their coronation “VII Kal Mar...apud Westmonasterium”.
Her relationship with her husband steadily deteriorated over the years, culminating in her flight to France to seek the protection of her brother Philippe V King of France. In 1324, she started a love affair with Roger Mortimer, and together they plotted her husband's overthrow. She was declared head of the Council of Regency by Parliament on the deposition of her husband. However, her rule was unpopular. She signed an unfavourable treaty with France and recognised Robert Bruce as king of Scotland for the first time. In addition, Mortimer alienated the barons with his territorial ambitions. Her son seized power, had Mortimer arrested after a Great Council meeting at Nottingham 19 Oct 1330 and condemned him to death. Isabelle thereafter lived in retirement. Froissart records that Isabelle went to "Ostrevant en Haynau en un chastel…Buignicourt dont messires Nicoles d´Aubrecicourt estoit sires".
The Chronicon Angliæ records the death “die Sancti Rufi martyris” of “domina mater regis Edwardi domina Ysabella” and her burial “in ecclesia Fratrum Minorum Londoniis”, dated to 1357 from the context. 1
