A courtier is a person who attends the court of a monarch or other royal personage. Courtiers often serve in various roles, such as advisors, diplomats, or entertainers, and they are typically involved in the social and political life of the court. Their influence can be significant, as they may help shape decisions and policies through their relationships with the ruler. Historically, courtiers were essential in royal courts, such as those in France during the reign of Louis XIV or in England during the Tudor period. They navigated complex social hierarchies and often engaged in political maneuvering to gain favor and power within the royal household.
