Froissart Book 1 Chapter 21. 1328. [his former son-in-law] King Charles of France (age 33), son to the fair king Philip, was three times married, and yet died without issue male. The first of his wives was one of the most fairest ladies in all the world, and she was daughter to the earl of Artois. Howbeit she kept but evil the sacrament of matrimony, but brake her wedlock; wherefore she was kept a long space in prison in the castle Gaillard [Map], before that her husband was made king. And when the realm of France was fallen to him, he was crowned by the assent of the twelve douze-peers¹ of France, and then because they would not that the realm of France should be long without an heir male, they advised by their counsel that the king should be remarried again; and so he was, to the [his daughter] daughter of the emperor Henry of Luxembourg, sister to the gentle [his son] king of Bohemia (age 31); whereby the first marriage of the king was fordone, between him and his wife that was in prison, by the licence and declaration of the pope that was then. And by his second wife, who was right humble, and a noble wise lady, the king had a [his granddaughter] son, who died in his young age, and the queen also at Issoudun [Map] in Berry. And they both died suspiciously, wherefore divers persons were put to blame after privily. And after this, the same king Charles was married again the third time to the daughter (age 18) of his uncle, the lord Louis earl of Evreux, and she was sister to the king of Navarre (age 21), and was named queen Joan. And so in time and space this lady was with child, and in the mean-time the king Charles her husband fell sick and lay down on his death-bed. And when he saw there was no way with him but death, he devised that if it fortuned the queen to be delivered of a son, then he would that the lord Philip of Valois should be his governour, and regent of all his realm, till his son come to such age as he might be crowned king; and if it fortuned the queen to have a daughter, then he would that all the twelve peers of France should take advice and counsel for the further ordering of the realm, and that they should give the realm and regaly to him that had most right thereto. And so within a while after the king Charles died, about Easter in the year of our Lord Mcccxxviii., and within a short space after the queen was delivered of a daughter.
