What are the reasons for the establishment of an absolute monarchy?

The rallying of the peasantry around the monarchs and the support of the cities, which were hindered by feudal fragmentation for trade and the creation of manufactures, petty chivalry made the prerequisites for the transition from a feudal and estate-representative monarchy to an absolute one, with a strong central power and the concentration of all power in the hands of the monarch.

Struggling with the remnants of feudalism, the kings tried to destroy or deprive the power of large feudal lords, taking away their lands, creating a regular army, a government apparatus.
