The Dukes of the United Kingdom are high-ranking nobles who hold the title of "Duke," which is the highest hereditary title in the British peerage system. This title is often associated with large estates and significant historical influence. Dukes typically belong to the aristocracy and may have roles in the House of Lords, the upper chamber of the UK Parliament. There are several notable dukedoms, such as the Duke of Cornwall and the Duke of Edinburgh. Each duke may have specific responsibilities and privileges, including the right to sit in the House of Lords and participate in ceremonial events. The title is often passed down through generations, maintaining the family's noble lineage.
