Lincolnshire, England derived from the merging of the territory of the ancient Kingdom of Lindsey with that controlled by the Danelaw borough Stamford. For some time the entire county was called 'Lindsey', and it is recorded as such in the Domesday Book. Later, Lindsey was applied to only the northern core, around Lincoln; it was defined as one of the three 'Parts of Lincolnshire', along with Holland in the south-east and Kesteven in the south west. In 1888 when county councils were set up, Lindsey, Holland and Kesteven each were authorized to have separate "Part" councils. These survived until 1974, when Holland, Kesteven, and most of Lindsey were merged into Lincolnshire, and the northern part, with Scunthorpe and Grimsby, going to the newly formed non-metropolitan county of Humberside, along with most of the East Riding of Yorkshire. An additional local government reform in 1996 abolished Humberside, and the parts south of the Humber became the unitary authorities of North Lincolnshire and North East Lincolnshire. These areas became part of Lincolnshire for ceremonial purposes, such as the Lord-Lieutenancy, but are not covered by the Lincolnshire police. These two authorities are in the Yorkshire and the Humber region of England. The remaining districts of Lincolnshire are Boston, East Lindsey, Lincoln, South Holland, South Kesteven, North Kesteven and West Lindsey. They are part of the East Midlands region.
