Each archdeacon has responsibility for church buildings and clergy discipline in her/his respective archdeaconry.
The archdeaconry, at that point covering the whole county of Derby, was transferred by Order in Council to the new Diocese of Southwell on 5 February 1884[1] and then split on 18 October 1910 — creating the Archdeaconry of Chesterfield — such that at its 2022 dissolution, Derby archdeaconry covered roughly the southern half of Derbyshire.
At the point of their dissolution: the Archdeaconry of Derby was divided into the deaneries of Derby City, Dove and Derwent, Mercia, and South East Derbyshire; and the Archdeaconry of Chesterfield, was divided into the deaneries of Carsington, Hardwick, North East Derbyshire, and Peak.
On 6 June 2022, Libby Lane, Bishop of Derby, dissolved the two existing Archdeaconries of Derby and of Chesterfield in order to erect three new Archdeaconries: of Derby City and South Derbyshire, of East Derbyshire, and of Derbyshire Peak and Dales.
