courtier

n. one who attends a royal court

A courtier is a person who attends upon, and thus receives a privileged position from a powerful person, usually a head of state. In the United States, the term has taken on negative connotations as a synonym for favorite or hanger-on. It is usually also used in a historical context, especially to describe the attendants of a luxurious autocrat such as Louis XIV of France. This context is used by many to make the word quaintly old-fashioned and irrelevant in contemporary circumstances, although "placemen" and rewarded campaign-donors in the American political system are contemporary examples of de facto courtiers.
