A Duke and Duchess are noble titles in the British peerage system. A Duke is the highest rank of the nobility, often overseeing large estates and holding significant influence. The title is typically inherited, passed down through generations, and can also be granted by the monarch. The title of Duchess is the female equivalent of a Duke. A Duchess may be the wife of a Duke or hold her own title in her own right. Both titles come with ceremonial duties and responsibilities, often involving public appearances and charitable work within the community, reflecting their status in society.
