The nobility of the United Kingdom refers to a social class that has historically held titles and privileges. This class includes various ranks such as dukes, marquesses, earls, viscounts, and barons. Nobility often owns large estates and has played significant roles in the country's history, politics, and culture. Noble titles can be hereditary, passed down through generations, or granted by the monarch. The British monarchy, represented by figures like Queen Elizabeth II, has the authority to bestow these titles. While the power of the nobility has diminished over time, they still hold ceremonial roles and contribute to the nation's heritage.
