After the War of the League of Cambrai, there was a tentative peace throughout Europe. It would not last long.
In 1515, King Louis XII died of gout, leaving his twelve-year-old son as king, Almost immediately, his regent and heir, Duke Francois made sure to consolidate his power by affirming his wife's rights as Duchess of Brittany. He wrote to King James, suggesting a match with Prince Arthur and his sister-in-law, Princess Renee. He then petitioned for the marriage betrothal between the new King Louis XIII and Eleanor of Austria to be annulled. Rumors swirled that he wanted the new king to marry Madeleine de La Tour d'Auvergne so France could reclaim the lands taken by the Lion of York.
King Philip of Castile and Duke Henry were equally appalled by the overreach of the French regent, both promising retribution if he continued with his plan. Tensions continued to boil over the months especially when the Duchess of York announced her pregnancy. Henry was overjoyed, pleased that he would soon have a son. Meanwhile as he sought another bridegroom for his eldest daughter, King Philip, alongside Emperor Maximilian, arranged a double wedding between his eldest son Charles and Anne of Hungary and Bohemia alongside his daughter Maria and Crown Prince Louis of Hungary and Bohemia.
It was during this time that Eleanor became acquainted with Count Fredrick, the fourth son of the Elector Palatine. It was said that the young count comforted the infanta over France's plot to break her betrothal. Rumors swirled around them, although King Philip had them both swear publicly that nothing untowed had happened between them. He sent Eleanor to Burgundy where she would be watched by her paternal aunt, Margaret who had some great sympathy for her niece, having gone through a similar situation with the late King Charles VIII.
Meanwhile, Katherine did not give a fig who the King of France married (although she was outraged on her niece's behalf), instead she focused on someone far more important, the marriage between Arthur and Isabel of Portugal. While a wedding of proxy would happen once Arthur turned sixteen, Isabel would not come to England until Arthur was eighteen. Katherine arranged for Margaret Pole to act as Isabel's duenna, wanting her to be prepared for the English court.
A year after the death of his French rival, King Fernando passed away. Neither Philip nor Juana mourned for him, instead riding to Aragon immediately to ensure that no one tried to take the crown from them. While popular fiction has Philip and Juana being joyous at the death of the overbearing Fernando, in truth they acted quite somber, treating their hasty movements such as removing Fernando's favorites from office as a grim necessity. They declared their son, Charles, as Prince of Asturias and Girona. Wanting to ensure that they kept their treaty with Portugal, they offered their second daughter, Infanta Isabel for the Crown Prince John.
For months, Duke Henry was crowing to everyone would could hear him that he would soon have a bouncing baby boy. He even debated what he would name his son, Arthur, Henry or Edward. But in February of 1515, Duchess Anne birthed a healthy girl. Thankfully, despite being thrown, Henry was overjoyed at having a daughter, proclaiming she would be named after his favorite sister, who was due to birth her first child in March. Henry and Anne were absolutely smitten with their daughter, but Henry was adament that the only way to safeguard his lands from the French was to have a son. He also feared what might happen should King Arthur be unable to conceive.
Shockingly he mentioned this to the Dowager Princess Katherine. Even more shockingly she did not take offense. Although Katherine was certain her son would have plenty of healthy children with Infanta Isabel, she knew that Arthur could die prematurely like his father. For the first time in years, Katherine and Henry were on the same page and drew up an act of succession. It would go from Arthur, his issue, Henry, his issue, and then Margaret, her Scottish children and lastly Mary and her children.
Margaret of course fumed that her son was placed behind Henry's daughter, wondering if there was anything her brother and her sister-in-law would not do to insult her family. She wrote to her mother, begging her to intervene on her grandson's behalf. Elizabeth of York wrote back a sharp letter that she would not speculate on matters that would only come about if a great tragedy happened.
Queen Mary of Denmark, Norway, and Sweden had really no opinion of such matters, instead focusing on being a new mother to her son, Prince Hans. She did however write to the two Arthurs, consoling them to allow the adult's petty squabbles affect them.
Meanwhile in France, after a year of negotiations, Duke Francois finally came to an agreement with Pope Leo with the Concordat of Bologna. Part of the agreement was the annulment of the betrothal between King Louis and Infanta Eleanor. No sooner had he accomplished that, did Francois announce the future marriage of Louis and Madeleine de La Tour d'Auvergne.
