Eleanor was a loyal and faithful consort to Henry, but she brought in her retinue a large number of cousins, "the Savoyards," and her influence with the King and her unpopularity with the English barons created friction during Henry's reign.[9] Eleanor was devoted to her husband's cause, stoutly contested Simon de Montfort, raising troops in France for Henry's cause. On 13 July 1263, she was sailing down the Thames when her barge was attacked by citizens of London.[10] Eleanor stoutly hated the Londoners who returned her hatred; in revenge for their dislike Eleanor had demanded from the city all the back payments due on the monetary tribute known as queen-gold, by which she received a tenth of all fines which came to the Crown. In addition to the queen-gold other such fines were levied on the citizens by the Queen on the thinnest of pretexts.[11] In fear for her life as she was pelted with stones, loose pieces of paving, dried mud, rotten eggs and vegetables, Eleanor was rescued by Thomas Fitzthomas, the Mayor of London, and took refuge at the bishop of London's home. In 1272 Henry died, and her son Edward, who was 33 years old, became Edward I, King of England. She remained in England as queen dowager, and raised several of her grandchildren—Edward's son Henry and daughter Eleanor, and Beatrice's son John. When her grandson Henry died in her care in 1274, Eleanor went into mourning and gave orders for his heart to be buried at the priory at Guildford which she founded in his memory. She retired to a convent; however, remained in contact with her son, King Edward, and her sister, Queen Margaret of France. Eleanor died on 24/25 June 1291 in Amesbury, eight miles north of Salisbury, England. She was buried on 11 September 1291 in the Abbey of St Mary and St Melor, Amesbury on 9 December. The exact site of her grave at the abbey is unknown making her the only English queen without a marked grave. Her heart was taken to London where it was buried at the Franciscan priory.[12]
