He expected that all would submit to what it seemed to him he was charged by God to establish. His brother the count of Anjou, had, on trial, condemned a knight; and the latter, on appealing to the king’s court, was imprisoned by the count. The king let his brother know that there was but one king in France and although Charles was his brother, he would not be treated in any different ways as regarded justice. The count of Anjou had to release his prisoner and came in person to oppose the appeal at the king’s court, which, however, was decided in favour of the knight. One of the most powerful lords of the realm, the lord of Coucy, caused three young men to be hanged for offence against the hunting laws, and although all the barons pleaded for him he was ordered a heavy fine. A lord cried with irony, “If I were king I would hang all the barons; for the first step taken, the second costs nothing.” The king heard and called him back. “How, Jean, you say that I should hang all my barons. Certainly I shall not do it, but I will punish them if they do wrong.” We have seen how the reputation for equity of the good king was so well established that the English barons in revolt against their king chose Louis as arbitrator, an example followed by the counts of Bar and Luxemburg. The right of coinage belonged to more than eighty lords who sometimes made bad money. St. Louis decided that his own should have circulation throughout the entire kingdom and alone should be legal tender in the royal domain and those whose lords had not the right of coinage; that the seigniorial coinage should only be legal in the province of the lord who issued it and that this lord could only strike off the _tournois_, and _parisis_,[11] and other coins whose legal value was fixed by relation to the _tournois_ in the ordinance. Thus the king ruled, in absolute power, in his own domain. He recognised elsewhere seigniorial rights, but limited them in the interest of the subjects whose protector he was. His money circulated everywhere. It only remained for the king to coin better _parisis_ and better _tournois_ than those of the lords; which he did. His money, like his justice, was worth more than his vassal’s. Another measure was extremely useful to commerce. It made the lords responsible for the policing of the roads through their domains. In Paris he established the royal watch and had drawn up by the provost, Étienne Boileau, the ancient rules concerning the hundred trades which existed in the town, in order to infuse peace and order into industry as he had done in the country. These trades grouped themselves into great corporations; in the fifteenth century all the Parisian merchants formed six bodies of “arts and trades.”
