Queen Isabella I of Castile – The attempted alliance with Pedro Girón

During her youth, several suitors had been considered for the future Queen Isabella I of Castile.

In 1466, one of the rebels suggested a marriage with Isabella as the best way to get his family’s loyalty back. In this plan, Isabella was to marry Pedro Girón Acuña Pacheco, who was also 18 years her senior. Her half-brother, King Henry IV, agreed to the match, but Isabella was horrified as she considered this match to be beneath her dignity.

Pedro’s brother, Juan Pacheco, was prepared to offer 3,000 lancers and a loan of 70,000 doblas. King Henry told Pedro to “come as fast as possible.”¹

Isabella sank to her knees and began to pray, begging God to free her from the match. She had not been so vehemently opposed to the match with the King of Portugal as this was, at least, a dignified match. As Pedro rode towards the court, he fell ill and died ten days later on 2 May 1466, much to Isabella’s relief. Queen Joan had not openly opposed her husband’s decision, but she had been against the match.²

King Henry was crestfallen.
