During the Age of Discovery, civilizations encountered each other for the first time, and—although it was a period of conquest and destruction—it was also one of global trade and the exchange of ideas. Centuries later, argues the author of Black and British, we see how the Industrial Revolution transformed the world. Using art as a lens for viewing these changes, David Olusoga ranges from the cotton mills of the Midlands to Napoleon's conquest of Egypt, the decimation of both Native American and Maori populations, and the advent of photography in Paris in 1839.
