Born on 29th September, 1252, at Kenilworth Castle, Eleanor de Montfort was the only daughter and sixth child of Eleanor of England. Her mother was the fifth and youngest child of King John and Isabella of Angouleme, and sister of Henry III. Her father was Simon de Montfort, Earl of Leicester, leader of the rebels in the Barons’ War.
Eleanor had 5 older brothers; Henry, Simon, Amaury, Guy and Richard.
Her father, Simon de Montfort, is remembered as one of the founders of representative government. He was a leading figure of the Second Barons’ War. He and his eldest son, Henry, were killed at the Battle of Evesham on 4th August 1265. On her father’s death, Eleanor fled to exile in France with her mother. The women settled at the Abbey at Montargis until Eleanor of England’s death there in 1275.
In 1265, in return for Welsh support, Simon de Montfort had agreed to the marriage of his daughter, Eleanor, to Llewelyn ap Gruffydd, Prince of Wales. De Montfort’s downfall had postponed the marriage, but in 1275, in a move guaranteed to rile Edward I, King of England, Llewelyn reprised his marriage plans and the couple were married by proxy whilst Eleanor was still in France.
Shortly after, Eleanor set sail for Wales, accompanied by her brother, Amaury, a Papal Chaplain and Canon of York. Believing the marriage would ‘scatter the seeds which had grown from the malice her father had sown’, Edward arranged for Eleanor to be captured at sea. When Eleanor’s ship was taken in the Bristol Channel, the de Montfort arms and banner were found beneath the ship’s boards.
Eleanor was taken to close captivity at Windsor, whilst her brother Amaury was imprisoned at Corfe Castle for 6 years.
In 1276 Llewelyn having refused to pay homage to Edward I, and was declared a rebel. Faced with Edward’s overwhelming forces, and support slipping away, Llewelyn was forced to submit within a year. The Treaty of Aberconwy reduced his lands to Gwynedd, but paved the way for his marriage to Eleanor, at last; it’s possible that the marriage was one of the conditions of Llewelyn’s submission.
The marriage of Eleanor de Montfort and Llewelyn ap Gruffydd was an extravagant affair, celebrated at Worcester Cathedral on the Feast of St Edward, 13th october 1278. The illustrious guest list included Edward I and Alexander III, King of Scots. Edward’s brother, Edmund of Lancaster gave Eleanor away at the church door, and Edward paid for the lavish wedding feast.
While the marriage did not prevent further struggles between the Welsh and the English king, there was relative peace for a short time and Eleanor may have encouraged her husband to seek political solutions. She is known to have visited the English court when Princess of Wales; and was at Windsor on such a visit in January 1281.
However, on 22nd March, 1282, Llewelyn’s younger brother, Dafydd, attacked the Clifford stronghold of Hawarden Castle and Llewelyn found himself in rebellion against Edward I yet again. At the same time, Eleanor was in the final few months of her pregnancy and Llewelyn held off taking the field until the birth of his much hoped for heir.
Eleanor and Llewelyn’s only child, a daughter, Gwenllian, was born on 19th June 1282; Eleanor died 2 days later.
Llewelyn himself was killed in an ambush on 11 December of the same year, at Builth, earning himself the name of Llewelyn the Last – the last native Prince of Wales.
Gwenllian was taken into Edward I’s custody, and sent to be raised at the convent at Sempringham, where she eventually became a nun. She died there on 7th June 1337, the last of her father’s line – and the last de Montfort. She was never allowed to speak, hear or learn her native language.
Eleanor de Montfort was the first woman known to have used the title Princess of Wales. She was buried alongside her aunt Joan, illegitimate daughter of King John and wife of Llewelyn the Great, at Llanfaes on the Isle of Anglesey.
