Baron

Baron is a member of the lowest order of the British nobility, or of a foreign nobility of similar rank. In Britain, barons are usually addressed or referred to as "Lord", but not as "Baron". Formerly, a baron was also a person holding land or property from the sovereign or a powerful overlord, however, it has now become a historical term. Any important or powerful person in a specified business or industry is also called a baron, such as a mining baron.
