A barony is a historical title of nobility that typically refers to the domain or estate owned by a baron. In the feudal system, a baron was a nobleman who held land granted by a higher-ranking lord, often in exchange for military service. The barony served as a local administrative unit, with the baron exercising authority over the land and its inhabitants. Baronies were common in medieval Europe, particularly in countries like England and France. The title of baron can still exist today, often as a ceremonial or honorary title, but the feudal responsibilities associated with it have largely disappeared.
