Why did the Industrial Revolution begin in Britain, and how did it develop between 1780 and 1850?

The Industrial Revolution began in Great Britain, the nation created by the formal union of Scotland, Wales, and England in 1707. The transformation in industry was something new in history, and it was unplanned. It originated from a unique combination of possibilities and constraints in late-eighteenth-century Britain. With no models to copy and no idea of what to expect, Britain pioneered not only in industrial technology but also in social relations and urban living.
