Eleanor was born in 1161 and her marriage had some long lasting consequences in terms of diplomatic, dynastic and cultural influences.
She was Henry II and Eleanor of Aquitaine’s second daughter. Her elder sister, Matilda, was five years older than her. When she was 3-years-old she was joined in her nursery by a sister Joanna and in 1166 by her youngest brother – John. We’ll leave her brawling older brothers to one side on this occasion.
When she was 3-years-old her father arranged a marriage for her to Frederick V, who was the eldest son of the Holy Roman Emperor and still an infant. However the Duke of Swabia died before the marriage could go ahead. Instead, a marriage was arranged to King Alfonso VIII of Castile who was 7-years-old. Eleanor was still only 9-years-old but it secured Aquitaine’s border. For Alfonso it meant that his father-in-law would be an ally against the king of Navarre. The marriage did not take place until Eleanor was 12-years-old. The couple would go on to have twelve children of whom seven survived infancy. It would be Eleanor who introduced the culture of Aquitaine to her adopted home and who acted as ambassador between her husband and her brothers.
The young bride would meet with her mother again when Eleanor of Aquitaine came to collect her granddaughter, Urraca, in 1200, when it was proposed that she should marry Prince Louis of France. Eleanor of Aquitaine spent two months at her daughter’s court and when she left Castile she took another of her granddaughters, Blanca, as Louis’s intended bride rather than Urraca. Blanche as she would be known became Louis’ queen and the mother of King Louis IX of France while Urraca would become Queen of Portugal.
Relations between Alfonso and Henry were not always so cordial. In 1200, or thereabouts, Alfonso tried to claim Gascony as part of Eleanor’s dowry. In 1205 he even invaded the territory in her name. Historians agree that it is highly unlikely that Henry II would have granted such an important territory to his daughter. By then Eleanor’s brother, John, was on the throne and it was Eleanor who was sent to visit her brother resulting in a peace accord. The argument was never truly settled because her grandson Alfonso X of Castile claimed the duchy stating that the dowry had never been paid in full.
Eleanor was clearly her mother’s daughter, holding much territory throughout her husband’s kingdom and ruling them in her own right or on behalf of her husband. In 1204, when Alfonso made his will, he stipulated that she was to be their eldest son’s regent and his executor. He died in October 1214. Unfortunately Eleanor died only 26 days after her husband and was buried beside him at Burgos.
And she understood the importance of making strategic marriage alliances. It was she who helped make the match between her daughter Berengaria and Alfonso IX of Leon even though the union was later dissolved on grounds of consanguinity. Berengaria, who was Eleanor of Castile’s grandmother, would become her bother’s regent and eventually Queen of Castile in her own right when her brother, Henry I, was killed by a falling roof tile. She abdicated soon after becoming queen, in favour of her son who became Ferdinand III.
And of course – for those of you who are keeping track it means that Eleanor of Castile and Edward I were related within the prohibited degrees of consanguinity along yet another line of the family tree. They were first cousins several times removed and shared kinship inside a web of royal families – Angevin, Capetian and Iberian.

Prince Henry was born on 11 Feb 1155, the second of Henry II and Eleanor of Aquitaine’s sons. Five years later he married the daughter of King Louis of France – Marguerite, her dowry was the Vexin region and Henry’s father King Henry II was keen to extend his empire. At seven Prince Henry was sent off to the household of Thomas Becket – the arrangement didn’t last long.
Unfortunately the Young King expected power and finances to go with the title. When this was not forthcoming he revolted against his father in 1173. Henry II was ultimately victorious in the family dispute but one of the consequences was the imprisonment of Eleanor of Aquitaine who had sided with her sons. The Young King got more money out of the deal but no more power although he was sent to fulfill various ceremonial duties on his father’s behalf. Instead of political power the Young King turned to the tournament and jousting.
William Marshall had his first taste of real battle at Neufchatel in 1166 when he demonstrated his bravery but failed to take any of his opponents for ransom. Once peace was restored to Normandy Marshall, now a knight, found himself without a mesnie or household.
19 December 1154 – Henry II, also known as Henry FitzEmpress  was crowned at Westminster Abbey along with his wife Eleanor of Aquitaine. Young Henry ascended to the throne after King Stephen’s death according to the agreement made at the Treaty of Wallingford that marked the end of the civil war that had raged between Stephen and Henry’s mother the Empress Matilda for nineteen long years. Henry’s coronation brought with it the promise of peace and incorporated England into a vast empire which Henry’s youngest son John would ultimately lose.
