Derby (/ˈdɑrbi/ DAR-bi) is a city and unitary authority in the East Midlands region of England. It lies upon the banks of the River Derwent and is located in the south of the ceremonial county of Derbyshire. In the 2011 census, the city had a population of 248,700.
The Roman camp of 'Derventio' was probably at Little Chester/Chester Green (grid reference SK353375); The site of the old Roman fort is at Chester Green. Later the town was one of the 'Five Boroughs' (fortified towns) of the Danelaw.
Djúra-bý, recorded in Anglo-Saxon as Deoraby "Village of the Deer". This popular belief is asserted by Tim Lambert who states, "The name Derby is derived from the Danish words deor by meaning deer settlement" without reference or proof. However some assert that it is a corruption of the original Roman name 'Derventio'. The proven origin of the name "Derby" would seem to be elusive.
The name could also be linked with the river which flows through it, the Derwent, meaning 'oak'.
