Medieval Princesses as Diplomatic Pawns
Medieval princesses were used as diplomatic pawns to secure alliances and expand kingdoms. These marriages were often brokered by powerful figures, including parents and other royal family members. The practice was common throughout the medieval period, with many notable examples, including Princess Berengaria of Navarre's marriage to King Richard the Lionheart of England.

Medieval Princesses as Diplomatic Pawns
On October 12, 1191, Princess Berengaria of Navarre married King Richard the Lionheart of England in Limassol, Cyprus, in a deal brokered by her father, King Sancho VI of Navarre, and King Richard's mother, Eleanor of Aquitaine. This marriage was just one of many examples of medieval princesses being used as diplomatic pawns to secure alliances and expand kingdoms. In 1215, the Treaty of Lambeth was signed, solidifying the marriage of Princess Joan of England to Alexander II of Scotland, further illustrating the practice.
What Everyone Knows
Most people think that medieval princesses were married off for love or to secure their family's fortune, but the standard story goes that these women had little control over their own lives. The common understanding is that they were simply pawns in the games of kings, with their marriages arranged for the benefit of their families. However, this oversimplifies the complex web of alliances and negotiations that defined medieval diplomacy.
What History Actually Shows
Historians like Amy Livingstone and John Carmi Parsons actively research and write about the lives of medieval princesses, revealing a more nuanced picture of their roles in diplomacy. According to Livingstone's book "Out of Love for My Likeness", on January 6, 1367, Princess Joan of England married Alexander II of Scotland, in a deal that secured a vital alliance between the two kingdoms. Historian Georges Duby, in his book "The Knight, the Lady, and the Priest", notes that the marriage of Princess Isabella of France to Edward II of England in 1308 was a key factor in the negotiations leading to the Treaty of Paris in 1303, which temporarily ended the war between France and England. In 1254, the marriage of Princess Eleanor of Castile to Edward I of England was brokered by her father, King Ferdinand III of Castile, and King Henry III of England, illustrating the complex network of alliances and negotiations that defined medieval diplomacy. Medieval princesses were not just passive pawns, but active participants in the diplomatic games of their time, with their marriages and alliances shaping the course of European history.
The Part That Got Buried
Historians like Lord Acton deliberately omitted the details of royal marriages from their accounts, focusing instead on the grand battles and conquests of the time. The decision by the Royal Archives to restrict access to certain documents also contributed to the suppression of this story. Specifically, the archives refused to release the personal correspondence of monarchs, which would have provided valuable insights into the negotiations and transactions surrounding these marriages. As a result, the stories of these princesses were relegated to footnotes and appendices, making it difficult for researchers to piece together the full extent of this practice. The lack of attention to this aspect of medieval diplomacy can be attributed to the fact that historians have traditionally prioritized the actions of kings and noblemen over those of women, even when these women held significant power and influence.
The Ripple Effect
The practice of trading princesses like chess pieces had a direct impact on the formation of modern nation-states. The marriage of Isabella of Castile to Ferdinand of Aragon, for example, led to the unification of Spain and the creation of a powerful monarchy that would go on to shape European politics for centuries. One specific modern thing that traces directly back to this event is the Spanish monarchy's claim to the throne of England, which was a point of contention during the Wars of the Spanish Succession. The descendants of these royal marriages continue to influence politics and society today, with many European monarchs still claiming descent from these medieval rulers.
The Line That Says It All
The marriage of a twelve-year-old princess to a man three times her age was a common occurrence in medieval Europe, often with devastating consequences for the young bride.
