This book examines the career of Henry Scott, third Duke of Buccleuch (1746-1812), with particular focus on his relationship with his tutor and friend, the philosopher Adam Smith. Henry Scott, the third Duke of Buccleuch (1746-1812), presided over the management of one of the largest landed estates in Britain during a time of dramatic agrarian, social and political change. Tutored and advised by the philosopher Adam Smith, the Duke was also an important patron of the Scottish Enlightenment, lauded by the Edinburgh literati as an exemplar of patriotic nobility and civic virtue, while his alliance with Henry Dundas dominated Scottish politics for almost 40 years. Combining the approaches of intellectual, economic and landscape history, this book examines the life and career of the third Duke, focusing in particular on his relationship with Adam Smith and the improvement of his extensive Scottish estates. By examining the influence of one of the 18th-century's foremost philosophers of improvement upon the career of one Scotland's largest landowners, this book explores the various influences - intellectual, economic, moral and political - which helped shape Scotland's distinctive agricultural revolution.
