Tom Sutcliffe looks back three hundred years to the Hanoverian succession to the British throne. The curator Lucy Worsley explains how the German Georges claimed the crown and how they kept it. The Georgian period is also the setting for Paula Byrne's biography of Dido Belle, the daughter of an aristocrat and a captured West Indian slave. Also on the programme, the MP Chris Bryant explores the history of Parliament and the movement of power from King to democracy. But what of today's Royals? The director Rupert Goold's latest production follows the coronation of Prince Charles to examine what it means to rule Britannia.

Producer: Katy Hickman.
