Duke of Devonshire is a title in the Peerage of England, held by the senior branch of the Cavendish family. It was created by William III in 1694 for the 4th Earl of Devonshire in recognition of his support during the Glorious Revolution. Many of the holders of the title have been prominent in British political life over the last three centuries, particularly the 4th Duke, who served briefly as Prime Minister during the Seven Years’ War.
