A marquis is a noble title in various European countries, ranking above an earl or count and below a duke. The title often comes with specific responsibilities, such as governing a region or territory, known as a marquisate. Historically, marquises were granted land and privileges in exchange for military service or loyalty to a monarch. In modern times, the title of marquis is largely ceremonial and is often inherited. While the role has diminished in political power, it still holds cultural significance in countries like France and Spain, where aristocratic titles are part of the historical heritage.
