Map - Lincolnshire

Lincolnshire (abbreviated Lincs.) is a county in the east of England, with a long coastline on the North Sea. It is divided between the East Midlands and the Yorkshire and Humber regions. It borders Norfolk to the south-east, Cambridgeshire to the south, Rutland to the south-west, Leicestershire and Nottinghamshire to the west, South Yorkshire to the north-west, and the East Riding of Yorkshire to the north. It also borders Northamptonshire in the south for just 19 m, England's shortest county boundary. The county town is Lincoln, where the county council is also based.

The ceremonial county of Lincolnshire consists of the non-metropolitan county of Lincolnshire, which is in the East Midlands region, and the areas covered by the unitary authorities of North Lincolnshire and North East Lincolnshire, which are in the Yorkshire and the Humber region. The county is the second-largest of the English ceremonial counties and one that is predominantly agricultural in land use. The county is fourth-largest of the two-tier counties, as the unitary authorities of North Lincolnshire and North East Lincolnshire are not included.

The county has several geographical sub-regions, including the rolling chalk hills of the Lincolnshire Wolds, the Lincolnshire Fens (south-east Lincolnshire), the Carrs (similar to the Fens but in north Lincolnshire), the industrial Humber Estuary and North Sea coast around Grimsby and Scunthorpe, and in the south-west of the county, the Kesteven Uplands, rolling limestone hills in the district of South Kesteven.

During pre-Roman times, most of Lincolnshire was inhabited by the Corieltauvi people. The language of the area at that time would have been Common Brittonic, the precursor to modern Welsh. The name Lincoln was derived from Lindum Colonia.

Large numbers of Germanic speakers from continental Europe settled in the region following the withdrawal of the Romans. Though these were later identified as Angles, it is unlikely that they migrated as part of an organized tribal group. Thus, the main language of the region quickly became Old English. However, it is possible that Brittonic continued to be spoken in some communities as late as the eighth century.

Modern-day Lincolnshire is derived from the merging of the territory of the Kingdom of Lindsey with that controlled by the Danelaw borough of Stamford. For some time the entire county was called "Lindsey", and it is recorded as such in the 11th-century Domesday Book. Later, the name Lindsey was applied to the northern core, around Lincoln. This emerged as one of the three Parts of Lincolnshire, along with the Parts of Holland in the south-east, and the Parts of Kesteven in the south-west, which each had separate Quarter Sessions as their county administrations.

In 1888 when county councils were set up, Lindsey, Holland and Kesteven each received separate ones. These survived until 1974, when Holland, Kesteven, and most of Lindsey were unified into Lincolnshire. The northern part of Lindsey, including Scunthorpe Municipal Borough and Grimsby County Borough, was incorporated into the newly formed non-metropolitan county of Humberside, along with most of the East Riding of Yorkshire.

A local government reform in 1996 abolished Humberside. The land south of the Humber Estuary was allocated to the unitary authorities of North Lincolnshire and North East Lincolnshire. These two areas became part of Lincolnshire for ceremonial purposes, such as the Lord-Lieutenancy, but are not covered by the Lincolnshire police; they are in the Yorkshire and the Humber region.

The remaining districts of Lincolnshire are Boston, East Lindsey, Lincoln, North Kesteven, South Holland, South Kesteven, and West Lindsey. They are part of the East Midlands region.

The area was shaken by the 27 February 2008 Lincolnshire earthquake, reaching between 4.7 and 5.3 on the Richter magnitude scale; it was one of the largest earthquakes to affect Britain in recent years.
