William Cavendish, 1st Duke of Devonshire (25 January 1640  18 August 1707) was an English Whig politician who sat in the House of Commons of England from 1661 until 1684 when he inherited his father's peerage as Earl of Devonshire and took his seat in the House of Lords. Cavendish was part of the "Immortal Seven" which invited William of Orange to depose James II of England as part of the Glorious Revolution, and was rewarded for his efforts by being elevated to the Duke of Devonshire in 1694.
