Overview
Joan of Acre (April 1272 – 23 April 1307) was an English princess, a daughter of Edward I of England and Eleanor of Castile. The name "Acre" derives from her birthplace in the Holy Land while her parents were on a crusade.
She was married twice; her first husband was Gilbert de Clare, 7th Earl of Gloucester, one of the most powerful nobles in her father's kingdom; her second husband was Ralph de Monthermer, a squire in her household whom she married in secret.
Joan is most notable for the claim that miracles have allegedly taken place at her grave, and for the multiple references to her in literature.
Birth and childhood
Joan (or Joanna, as she is sometimes called) of Acre was born in the spring of 1272 in the Kingdom of Acre, Outremer, now in modern Israel, while her parents, Edward I and Eleanor of Castile, were on crusade. At the time of Joan's birth, her grandfather, Henry III, was still alive and thus her father was not yet king of England. Her parents departed from Acre shortly after her birth, travelling to Sicily and Spain before leaving Joan with Eleanor's mother, Joan, Countess of Ponthieu, in France. Joan lived for several years in France where she spent her time being educated by a bishop and "being thoroughly spoiled by an indulgent grandmother." Joan was free to play among the "vine clad hills and sunny vales" surrounding her grandmother's home, although she required "judicious surveillance."
