It is the third-largest city in the Yorkshire and the Humber region after Leeds and Sheffield, northern England's fourth-largest, sixth-largest in England and seventh-largest in the United Kingdom.

Historically part of the West Riding of Yorkshire, Bradford rose to prominence in the 19th century as an international centre of textile manufacture, particularly wool. It was a boomtown of the Industrial Revolution, and amongst the earliest industrialised settlements, rapidly becoming the "wool capital of the world"; this in turn gave rise to the nicknames "Woolopolis" and "Wool City".
