The British aristocracy refers to a social class in the United Kingdom that historically held significant power, wealth, and land. This class is often associated with titles such as Duke, Marquess, Earl, Viscount, and Baron. Aristocrats typically owned large estates and played important roles in politics and society, especially before the 20th century. Over time, the influence of the British aristocracy has diminished, particularly with the rise of democracy and changes in social structure. Today, while many aristocratic families still exist, their roles are largely ceremonial, and they often engage in charitable activities or public service rather than holding political power.
