In a week of programmes exploring the nature of power and the emergence of new rulers around the world 2000 years ago, Neil MacGregor takes us to Han Dynasty China. He tells the story of how the Chinese maintained loyalty and control by dispensing luxury gifts. He describes the world of the imperial Han through an exquisite lacquer wine cup that was probably given by the emperor to one of his military commanders in North Korea. The historian Roel Sterckx underlines the importance of lacquer for the period while writer Isabel Hilton looks at how the production of goods under state control has remained a consistent interest of the Chinese.Producer: Anthony Denselow
