I've been interested in Navarre's history for a while now (PS, if anyone has any book recommendations about Basque history feel free to tell me) looking for ways for them to survive for a lot longer, or even until modern day if that's possible.
One way I've found is making it so Henry I's eldest son, Theobald III, doesn't fall of a battlement at the castle at Estella. This leads to Theobold III ascending to the thrown instead of his sister, Joan, when Henry suffocates on his own fat, so Joan never marries Phillip IV, so Navarre never enters a personal union with France.
Theobald III was scheduled to be married to King Alfonso X's daughter, Violant (Who was seven by the way) in exchange for an alliance with Castile. Would this alliance last long? Or would Navarre just be absorbed into Castile in this timeline.
