The Oxford English Dictionary (definition of aristocracy)

The Oxford English Dictionary defines aristocracy as a form of government or social class where power and privilege are held by a hereditary nobility. It refers to a society in which certain families, often with titles or land, hold significant influence and status, passed down through generations. This class is distinguished from other social groups by inherited wealth, titles, and social standing, shaping politics, economics, and social relationships within a society. Essentially, aristocracy emphasizes the role of noble families in maintaining social hierarchy and leadership based on lineage and tradition.
