What Challenges did monarchs have in medieval times?

Medieval monarchs faced numerous challenges, including managing feudal relationships where local lords held significant power, often leading to conflicts over authority and loyalty. They also contended with threats from rival kingdoms, invasions, and internal rebellions, which could destabilize their rule. Additionally, maintaining a steady revenue stream for governance and military expenses was a constant struggle, as taxation often provoked dissatisfaction among their subjects. Lastly, the influence of the Church added another layer of complexity, as monarchs sought to balance religious authority with their own power.
