North Lincolnshire: History of area
The former districts of Glanford, Scunthorpe, and the southern part of Boothferry, were non-metropolitan districts of the county of Humberside from 1974 to 1996. Humberside was abolished that year and those three districts merged to form the new unitary authority area of North Lincolnshire, as part of an expanded Lincolnshire ceremonial county. The area had previously been within the Lincolnshire administrative county before 1974 as a collection of municipal boroughs, urban districts, and rural districts. The new district of North Lincolnshire was awarded borough status on 16 December 1996, allowing the chair of the council to take the title of mayor.
