Richard Temple-Nugent-Brydges-Chandos-Grenville, 2nd Duke of Buckingham and Chandos

Richard Plantagenet Temple-Nugent-Brydges-Chandos-Grenville, 2nd Duke of Buckingham and Chandos (11 February 1797 – 29 July 1861), styled Viscount Cobham from birth until 1813, Earl Temple between 1813 and 1822 and Marquess of Chandos between 1822 and 1839, was a British Tory politician. He served as Lord Privy Seal between 1841 and 1842.

Two events in his life were remarkable, given the era he lived in and the position he held in society as a duke: firstly, despite the great wealth to which he was born, he declared bankruptcy with debts of over a million pounds in 1847; secondly, he obtained a divorce at a time when it required an Act of Parliament.
