Chatham Papers

The Chatham Papers are the collected correspondence of William Pitt, 1st Earl of Chatham, and his son William Pitt the Younger, who each served as prime minister of Great Britain in the eighteenth century, now held at the British National Archives. The collection documents the political careers and personal affairs of two of the most significant British statesmen of their era, spanning father and son across successive generations of British government. Historians of eighteenth-century British politics and empire draw on the papers as a primary source for the careers of the two Pitts, though the source consulted for this description does not establish in detail exactly which years and subjects the collection covers.
