Historians of the Seventh Crusade have usually told its story from the perspective of its most famous participant: King Louis IX of France. Chroniclers such as Jean de Joinville, Louis’s friend and biographer, painted the campaign as a tale of Christian courage, royal piety, and tragic defeat. In these familiar accounts, the focus has been almost completely on what the Crusaders did.

Description

Berenguela and Blanche of Castile

Daughters of Alfonso VIII of Castile and Eleanor of England, Berenguela maintained strong connections with her sister Blanche, Queen of France. Their letters are in Latin. Latin was still, at the beginning of the 13th century, the language of writing, while French and Castilian became the languages ​​commonly spoken, even at court. Berenguela and Blanche were well-educated, competent and forceful like their formidable grandmother Eleanor of Aquitaine.

The two sisters will also lead a parallel existence, each exerting, in their own country, a comparable influence. Much like her younger sister Blanche in France, Berenguela presents an interesting case of co-rulership with her son in Castile. Furthermore, both have ties with warfare and played determinant roles in the success of military campaigns as well as access to – and maintenance of – the throne.

Berenguela and Blanche directed a great deal of their personal energy into assuring that all of their children were appropriately married. It was Blanche who suggested sending Joan of Ponthieu as a bride for her nephew Fernando after his first wife's death. Berenguela and Blanche became the mothers of fighting saints King Fernando III and King Louis IX.

In the Archives Nationales de France are nine letters written to King Louis VIII and his wife Blanche of Castile, during Louis’s brief reign from 1223 to 1226. These letters informed Louis VIII that Alfonso VIII of Castile had intended his throne to pass to a son of Louis and Blanche, if his own son Enrique died without heirs. Louis VIII should therefore immediately send his son to Castile, where his correspondents—the scions of several major Castilian noble houses—would take up arms to set him on the throne and overthrow the “foreigner” (alienus) who was in power. The most prominent of these Castilian magnates were Rodrigo Díaz de Cameros and Gonzalo Pérez de Molina. This conspiracy was an explicit attempt to dispose of the current Castilian monarchy and replace it with a new configuration of rulers. It was therefore a far more serious threat than either Rodrigo Díaz’s or Gonzalo Pérez’s earlier revolts had been. And it was aimed squarely at the legitimacy of the reigning monarchs.

The letters’ most perplexing feature is the suggestion that Blanche’s claim to the Castilian throne superseded Berenguela’s. Some historians have even taken this as evidence that Blanche was the elder sister, though that claim is patently false. Yet the plot to overthrow Fernando III was first of all an attempt to unseat Berenguela. It was through her that Fernando III claimed hereditary right and legitimate descent from Alfonso VIII. To say that Alfonso VIII had excluded Berenguela from the succession, and to describe Fernando as a “foreigner,” was to reject the Castilian identity that Berenguela had tried to reclaim during her ten years as a solitary queen in her father’s court, and that she had negotiated with varying success during her regency and the subsequent wars. It was to define her not as the daughter and sister of the latest kings of Castile, but as the cast-off wife of the king of León.

To be sure, Blanche and her sons were at least as French as Berenguela and Fernando III were Leonese. But the rebels were apparently willing to overlook this quibble; their appeal was directed as much to Louis VIII as to his queen. Besides, the threat of union with France was diminished by the fact that Blanche and Louis VIII had no fewer than five living sons at the time that they ruled France. The rebels never insisted that the son sent to them should be Louis VIII’s firstborn, and a younger brother’s accession in Castile considerably reduced the risk of union between the crowns. All five French princes were underage, but so much the better; the minorities of Alfonso VIII and Enrique I had proved how much power nobles could gain in a regency. Louis VIII was sufficiently intrigued by the rebels’ offer to have asked them for proof of their promised support. His wife, however, was likely to be less sympathetic. A combination of Blanche’s unwillingness to contribute to her older sister’s overthrow and Fernando III’s military successes after 1224 probably quashed the plot.
