(See also article on Derbyshire)
Derbyshire was traditionally divided into six hundreds, namely Appletree, High Peak, Morleyston and Litchurch, Repton and Gresley, Scarsdale, Wirksworth. These were based on the seven earlier wapentakes recorded in the Domesday Book, with the merging of Repton and Gresley wapentakes.
Derbyshire had a detached part in north-western Leicestershire, surrounding Measham and Donisthorpe. This escaped regularisation in 1844, and was incorporated into Leicestershire in 1888 when the county councils were set up. The thin strip of Leicestershire between the exclave and Derbyshire, containing Overseal and Netherseal, is now considered part of Derbyshire.
