How did centralized monarchies develop in Europe?

Centralized monarchies in Europe developed during the late Middle Ages as kings consolidated power by diminishing the influence of feudal lords and local nobility. This process was facilitated by the need for stronger governance to manage growing populations, economic expansion, and military conflicts. The establishment of bureaucracies, legal systems, and standing armies further empowered monarchs, allowing them to enforce their authority more effectively. Additionally, events like the Hundred Years' War and the rise of nation-states contributed to the centralization of power under a singular royal authority.
