How did the balance of power shift in the High Middle Ages?

During the High Middle Ages, the balance of power shifted significantly as monarchies began to centralize authority, diminishing the influence of feudal lords and the Church. Kings like those in England and France consolidated power through legal reforms and military campaigns, establishing stronger bureaucracies and standing armies. This shift also led to the rise of towns and a merchant class, fostering economic changes that further empowered the monarchy. Consequently, the feudal system weakened, paving the way for the modern nation-state.
