Sathnam Sanghera joins Desiree Reynolds for a discussion about his new book, Empireland: How Imperialism Has Shaped Modern Britain. The British Empire ran for centuries and covered vast swathes of the world. It is, as Sanghera reveals, fundamental to understanding Britain. However, even among those who celebrate the empire there seems to be a desire not to look at it too closely – not to include the subject in our school history books, not to emphasise it too much in our favourite museums. At a time of great division, when we are arguing about what it means to be British, Sanghera’s book urges us to address this bewildering contradiction. For it is only by stepping back and seeing where we really come from that we can begin to understand who we are, and what unites us.
