The Dukes of England are high-ranking nobles who hold the title of "Duke," which is one of the highest peerages in the British aristocracy. This title has been historically associated with land ownership and significant political influence. Dukes often manage large estates and have a role in the House of Lords, the upper house of the Parliament of the United Kingdom. The title of Duke was first created in the 14th century, with the Duke of Cornwall being one of the oldest. Today, there are several dukedoms, each associated with specific regions, such as the Duke of York and the Duke of Edinburgh. Dukes often participate in ceremonial duties and represent the monarchy at various events.
