Wales was divided into a number of separate kingdoms. The largest of these was Gwynedd in northwest Wales and Powys in east Wales. Gwynedd was the most powerful of the Welsh kingdoms. For one man to rule all of Wales during this period was rare. This was because of the inheritance system practiced in Wales. All sons received an equal share of their father’s property, including illegitimate sons, resulting in the division of territories.

The Principality of Wales was created in 1216 at the Council of Aberdyfi when it was agreed by Llywelyn the Great and the other Welsh princes that he was the paramount Welsh ruler and the other Welsh princes would pay homage to him. Although he never used the title, Llywelyn was the de facto Prince of Wales. Llywelyn dominated Wales for 45 years and was one of only two Welsh rulers to be called “the Great”, the other being his ancestor Rhodri the Great. Llywelyn was succeeded by his son Dafydd ap Llywelyn and then by his two grandsons who were the sons of his illegitimate son Gruffydd ap Llywelyn.

The campaign of King Edward I of England in Wales (1276 – 1284) resulted in Wales being completely taken over by England. It ended with the deaths of the last two native Princes of Wales: Llywelyn ap Gruffudd who was ambushed and killed in 1282 and his brother Dafydd ap Gruffydd, who was the first prominent person in recorded history to have been hanged, drawn, and quartered, in 1283. To ensure there would be no further members of the House of Aberffraw, the English imprisoned Dafydd ap Gruffydd’s two young sons for the rest of their lives at Bristol Castle and sent his daughter and the daughter of his brother Llywelyn ap Gruffydd to convents. To further humiliate the Welsh, King Edward I invested his son and heir, the future King Edward II, with the title Prince of Wales. Since then, the title has been granted (with a few exceptions) to the heir apparent of the English or British monarch.

Note: In Welsh, “ap” means “son of” and “ferch” means “daughter of”.

The wife of Llywelyn ap Gruffudd, Prince of Wales, Eleanor de Montfort was born at Kenilworth Castle in Kenilworth, Warwickshire, England, around Michaelmas (September 29) in 1252. King Henry III of England had granted Kenilworth Castle to Eleanor’s father in 1244. Eleanor was the youngest of the seven children and the younger and the only surviving of the two daughters of Simon de Montfort, 6th Earl of Leicester and Eleanor of England. Her paternal grandparents were Simon de Montfort, 5th Earl of Leicester and Alix de Montmorency, a French noblewoman. Her maternal grandparents were King John of England and Isabella of Angoulême. King Henry III of England was Eleanor’s maternal uncle and his four surviving children, King Edward I of England, Margaret of England, Queen of Scots, Beatrice of England, Countess of Richmond, and Edmund Crouchback, 1st Earl of Lancaster, were her first cousins.

Eleanor had six siblings:

The displeasure of the English nobility with King Henry III ultimately resulted in a civil war, the Second Barons’ War (1264–1267). The leader of the forces against King Henry III was Eleanor’s father Simon de Montfort, 6th Earl of Leicester. Simon de Montfort wanted to reassert the Magna Carta and force King Henry III to surrender more power to the baron’s council. When Eleanor was thirteen years old, her father Simon de Montfort, 6th Earl of Leicester and her eldest brother Henry de Montfort were killed at the Battle of Evesham. Today, Eleanor’s father is considered one of the fathers of representative government. Over the years, Simon de Montfort’s contributions have been remembered by the British Houses of Parliament. A bas-relief of Simon de Montfort, 6th Earl of Leicester hangs on the wall of the chamber of the United States House of Representatives where he is recognized as one of the 23 historical lawgivers.

After her husband’s death, Eleanor of England, Eleanor’s mother, organized a defense of Dover Castle against royalist troops, but in October 1265, the castle was taken by her nephew Edward, Prince of Wales (the future King Edward I). Eleanor of England’s possessions were confiscated by the Crown and she was exiled to France with her 13-year-old daughter Eleanor de Montfort. She sought refuge at a de Montfort stronghold, Montargis Abbey, founded by her husband’s sister Amicia de Montfort. With the influence of King Louis IX of France, King Henry III paid his sister compensation for her confiscated lands and goods in 1367. Eleanor of England lived the rest of her life as a nun at Montargis Abbey where she died on April 13, 1375, at the age of 60 and was buried. Her daughter Eleanor de Monfort remained with her mother until her death.

In 1265, a marriage contract had been concluded for a marriage between Eleanor de Montfort and Llywelyn ap Gruffudd, Prince of Wales. In 1275, Llywelyn ap Gruffudd, Prince of Wales and Eleanor de Montfort were married by proxy. While making her way from France to Wales by ship, Eleanor de Monfort was captured by agents of her first cousin King Edward I of England. She was held prisoner at Windsor Castle for nearly three years. Eleanor was finally released in 1278 following the signing of the Treaty of Aberconwy between King Edward I of England and Llywelyn ap Gruffydd, Prince of Wales. On October 13, 1278, the feast day of Saint Edward the Confessor, King of England, Llywelyn ap Gruffydd, Prince of Wales and Eleanor de Monfort were married in person at Worcester Cathedral in England with King Edward I giving the bride away and paying for the wedding feast.

Eleanor and Llywelyn ap Gruffydd had one child, a daughter Gwenllian ferch Llywelyn, also known as Gwenllian of Wales, born at the  Palace of Aber Garth Celyn in Gwynedd, Wales. Sadly, Eleanor died due to childbirth complications on June 19, 1282, aged 29 – 30. She was buried at Llanfaes Friary which had been founded by Llywelyn the Great, the grandfather of Llywelyn ap Gruffudd, in memory of his wife Joan, Lady of Wales, an illegitimate daughter of King John of England and Eleanor’s aunt, in the now vanished medieval town of Llanfaes, Anglesey, Wales.

On December 11, 1282, five months after the birth of his daughter Gwenllian and the death of his wife Eleanor, Llywelyn ap Gruffydd, Prince of Wales was one of 3,000 Welshmen killed at the Battle of Orewin Bridge near Builth Wells, Wales. He was ambushed, horribly murdered, and beheaded. His head was sent to London for public display, and it is thought that the rest of his body was interred at Cwmhir Abbey in Abbeycwmhir, Wales. On October 3, 1283, Llywelyn ap Gruffydd’s brother and successor Dafydd ap Gruffydd, Prince of Wales was brutally executed in Shrewsbury, England on the orders of King Edward I of England. Dafydd ap Gruffydd was the first prominent person in recorded history to have been hanged, drawn, and quartered. His head was placed on a pole in the Tower of London near the head of his brother Llywelyn. The days of an independent Wales were over. King Edward I of England had completed a conquest of Wales that resulted in his annexation of the Principality of Wales.

King Edward I of England wanted to make sure that there were no more claimants to the Welsh throne. Gwenllian ferch Llywelyn, the infant daughter of Eleanor de Monfrot and Llywelyn ap Gruffydd and Gwenllian’s first cousin Gwladys ferch Dafydd, Dafydd ap Gruffydd’s young daughter, were confined for life in remote convents in Lincolnshire, England, and never allowed freedom. Gwenllian died in 1337 and Gwladys died circa 1336. Dafydd ap Gruffydd’s two young sons 15-year-old Llywelyn ap Dafydd and 7-year-old Owain ap Dafydd, also Gwenllian’s first cousins, were imprisoned for the rest of their lives at Bristol Castle in England. Much of the time they were kept in cages. Llywelyn died in 1287 while Owain was last reported to be alive in 1325 when he would have been in his fifties.
