The nineteenth century was a time of massive growth for Britain. In 1800 it was overwhelmingly rural, agrarian, multilingual, and almost half-Celtic. A century later it was largely urban and English. The effects of the Industrial Revolution caused cities to swell enormously. London, for example, grew from about 1 million people to over 6 million. Abroad, the British Empire was reaching its apex, while at home the world came to marvel at the Great Exhibition of 1851 with its crowning achievement — the Crystal Palace. Historians Christopher Harvie and Colin Matthew present a comprehensive and authoritative guide to the social, economic, and political events that marked the era on which many believed the sun would never set.
