The Valois-Anjou army belongs to the lords serving Charles de Valois, King Philippe IV’s brother. During his whole life, Valois attempts to acquire a crown, but he does not manage because of unfortunate events, of a certain bad luck and of his notorious clumsiness. He represents the chief of barons par excellence, relentlessly defending the feudal values against the modern ideas of the king of France’s legists. In fact, he feels somewhat disgusted by commoners, and especially by those sitting on Philippe’s council, such as Enguerrand de Marigny and Guillaume de Nogaret.
Charles de Valois acquires the region of Anjou through Marguerite, daughter of Charles II d’Anjou, who gives it to him as a dowry. He is already progressing at a royal pace, having his own chancellor and an army, when in 1302, he dissociates himself from his brother, the king of France, and assumes control of his own kingdom which he calls Valois. Supported by a few knights and lords from his earldom, he takes over Reims, an independent archdiocese, and then forces the archbishop to crown him King of Valois. Unfortunately, the pope Clemens V refuses to recognise his coronation and excommunicates him.
The recent events weaken Charles Indeed, some of his vassals contest his power in response to the excommunication lying heavy on him. Many even attempt to rally to the French Crown which they recognise as the supreme authority. Quarrels then break out in Valois between the lords who are faithful to Charles, the ones who advocate for a blind submission to the Holy See and those who support Philippe of France.
However, in 1309, Valois manages to become allies with Philippe IV’s son, Charles de La Marche. This support allows him to regain the trust of several lords. Moreover, he becomes closer to the pope Iohannes XXII, who dissociates himself from Philippe and agrees to evaluate the possibility of lifting the excommunication. Pleased, the lord of Valois can now focus on his greatest ambition: to conquer Paris to take over the heart of France and become its king. He is close enough to the city to constitute a real threat and he is, from now on, ready to do anything to take over the French Crown.
