Indicate the prerequisites for the strengthening of royal power in the 13-14 centuries. How has the government changed?

Royal power is beginning to grow stronger due to several factors. The first is the creation of a good royal administration and judicial system. The second reason was that there was a weakening of the feudal farms due to the epidemic, and the liberated lands became the property of the king. The personal possessions of the king are expanding, the feudal militia is gradually replaced by the army. It was also important that the authorities supported the cities, which were unprofitable for feudal civil strife. This led to the centralization of power.
