Isabel de Clare, suo jure Countess of Pembroke

The death of Isabel Marshal – daughter of Isabel de Clare, one of Isabel and William’s ten children.

The daughter of Earl Richard ‘Strongbow’ Earl of Pembroke and Striguil and Lord of Leinster and Aoife of Leinster, Isabel grew up as part of the powerful de Clare family and following her brother Gilbert’s death became one of the wealthiest heiresses in the kingdom. She was placed by King Henry II, who did not trust Strongbow, in the care of Ranulf de Glanville, justiciar of England. 

In 1189 her marriage was arranged by Richard the Lionheart to William Marshal. The couple were happily married despite a thirty-five year age gap and never having met before their wedding in August that year. Isabel travelled by her husband’s side, took part in the management of their estates and issued writs. They went to Ireland in 1200 and she may have ruled Leinster in his absence. She continued to demonstrate her capacities when, Marshal was placed under arrest in 1207, she led a campaign against the province’s rebel barons.  She was pregnant at the time. She gave William ten children, five boys and five girls. Marshal recognised that his power and his wealth came from his wife, honoured, loved and respected her intelligence. In Leinster her presence in Marshal’s life gave his rule legitimacy – she was after all the grand daughter of the last king of Leinster.

Isabel managed her husband’s affairs in his absence and following his death she took control of her own inheritance corresponding with the justiciar of England, with the papal legate and with King Philip II of France.  After thirty years of marriage, William died. One of the last things he did was to join the Templars – forgoing the company of his wife and daughters in his final days.  Isabel was devastated by Marshal’s death but she worked closely with her family to preserve her inheritance.   She died ten months after her beloved husband. Her earldom did not survive her children. All five of the couples’ sons died without heirs.

Isabel was buried in Tintern Abbey next to her mother.

  1. The days when women knew their place without all this war with sex. She supported her man to receive his total trust and devote love .Seems a fair payout to me. No one rules in marriage but respect is a bond and plan as one against all else .Marshal was a good man I saw his castle at Chepstow and knew him as man of more than his times. When my ancestor became Countess Pembroke to her Herbert husband Chepstow was in ruins even then . Marshal had made his castle into a family home long before his rivals even dared to set in big panoramic windows into 12 feet deep stone defensive walls. No to his real name as Marshall of England was his job and all called him Marshal as name was forgotten I think.
