A barony is a historical title of nobility that typically refers to the domain or estate owned by a baron. In medieval Europe, a baron was a nobleman who held land granted by a king or higher-ranking noble in exchange for military service and loyalty. The barony often included various villages, farms, and resources, making it an important social and economic unit. Baronies were part of the feudal system, which structured society around relationships derived from the holding of land. The title of baron can still exist today in some countries, often as a ceremonial or honorary title, and is associated with the broader concept of the nobility.
