 Derby (population 234,000) is a city in England’s East Midlands on the banks of the River Derwent. In Anglo-Saxon it was recorded as ‘Deoraby’, meaning ‘Village of the Deer’. Derby is the county town of Derbyshire and was one of the main centres of the Industrial Revolution in Britain, home to the first water-powered silk mill and a major player in Britain’s cloth industry. Today, it is most important as a rail and motorcar manufacturer, with the Rolls-Royce factory situated in the city since 1907.
