This chapter presents the text of a lecture on the Industrial Revolution in Great Britain given at the British Academy's 2009 Keynes Lecture in Economics. This text suggests that the Industrial Revolution was Britain's response to the global economy that emerged after 1500 and that Britain's success in world trade resulted in one of the most urbanised economies in Europe with unusually high wages and cheap energy prices. The text here also highlights the contribution of Britain in the invention of (...) the steam engine and the cotton spinning machines and in scientific discoveries relating to atmospheric pressure.
