John II the Good: Captivity, Internal Crisis, and the Treaty of Brétigny (1350–1364) · HIGH MIDDLE AGES
The conflict between John II and Charles II of Navarre does not originate solely from a rivalry of prestige: it is rooted in fiefs, networks, and governmental decisions. The Angoulême affair crystallizes these tensions from the earliest months of the reign.
Charles II of Navarre believes he has rights to the County of Angoulême, based on prior agreements and promised compensations (castellanies and territorial arrangements) that he deems unrespected. Yet John II grants the county to his favorite, Charles of La Cerda, in December 1350.
This choice is a political affront: it strengthens a man of the royal party and deprives the Navarrese of a strategic foothold, while symbolically excluding him from the distribution of honors.
With the death of Philip VI, the de facto truce frays and tensions resume. Charles of La Cerda, appointed constable, leads an active campaign in Poitou and Saintonge. He takes Saint‑Jean‑d’Angély on August 11, 1351, illustrating royal power’s will to seize the initiative.
The campaign also has an internal dimension: it consolidates La Cerda’s position, which mechanically intensifies Navarrese resentment.
