What laws did Louis IX adopt?

The reforms carried out by Louis 9 in the 13th century strengthened the power of the king and his administration. Thus, the military reform allowed him to get out of the dependence of the feudal militia. The city militia is being created. Detachments of mercenaries appear in the country, he effectively fights vassals who refuse to submit. The next step was to ban private wars. The controversial issues that arose between the feudal lords of the kingdom were now decided by the court of the king. A royal council was also established. A single coin was introduced, the money of individual feudal lords was prohibited. All of this was aimed at combating fragmentation. Gradually, the estate-representative monarchy begins to dominate the country.
