| Administrative History | Sir William Cavendish and Bess of Hardwick's grandson William Cavendish (1552-1626) was a politician. In 1605 he was created Baron Cavendish and in 1618 created Earl of Devonshire. He was succeeded by his eldest son, William Cavendish, 2nd Earl of Devonshire (c.1590-1628) who served as Lord-Lieutenant of Derbyshire. Upon his early death, his son William Cavendish, 3rd of Devonshire (1617-1684) succeeded him, who also served as Lord-Lieutenant of Derbyshire. His son William Cavendish, 4th earl of Devonshire (1640-1707) succeeded him. The 4th Earl supported the Glorious Revolution in 1688, served in the royal household and in 1694 was created Marquess of Hartington and 1st Duke of Devonshire. The title Duke of Devonshire continued to pass down the family. The 5th Duke was noted for his marriage to society hostess Lady Georgiana Spencer (1757-1806). Their son the 6th Duke was known as the 'Bachelor Duke' and died unmarried in 1858, passing the dukedom to his cousin 2nd Earl Burlington, who became the 7th Duke. The 8th Duke was a noted statesman and had a 40 year political career holding posts including Secretary of State for India and Secretary of State for War, and declined the role of Prime Minister three times. He married Louise, Dowager Duchess of Manchester, who hence became known as the 'Double Duchess'. The 8th Duke died childless and was succeeded by his nephew. |
