Map - Northamptonshire

Northamptonshire ( abbreviated Northants.) is a county in the East Midlands of England. In 2015, it had a population of 723,000. The county is administered by two unitary authorities: North Northamptonshire and West Northamptonshire. It is nicknamed "The Rose of the Shires".

Covering an area of 2,364 square kilometres (913 sq mi), Northamptonshire is landlocked between eight other counties: Cambridgeshire to the east, Bedfordshire to the south-east, Buckinghamshire to the south, Oxfordshire to the south-west, Warwickshire to the west, Leicestershire and Rutland to the north, and Lincolnshire to the north-east—the last being England's shortest administrative county boundary, at 20 yards (19 metres). Northamptonshire is the southernmost county in the East Midlands.

Apart from the county town of Northampton, other major population centres include Kettering, Corby, Wellingborough, Rushden and Daventry. Northamptonshire's county flower is the cowslip. The Soke of Peterborough falls within the historic boundaries of the county, but its area has been part of the ceremonial county of Cambridgeshire since 1974.

Much of Northamptonshire's countryside appears to have remained somewhat intractable with regards to early human occupation, resulting in an apparently sparse population and relatively few finds from the Palaeolithic, Mesolithic and Neolithic periods. In about 500 BC the Iron Age was introduced into the area by a continental people in the form of the Hallstatt culture, and over the next century a series of hill-forts were constructed at Arbury Camp, Rainsborough camp, Borough Hill, Castle Dykes, Guilsborough, Irthlingborough, and most notably of all, Hunsbury Hill. There are two more possible hill-forts at Arbury Hill (Badby) and Thenford.

In the 1st century BC, most of what later became Northamptonshire became part of the territory of the Catuvellauni, a Belgic tribe, the Northamptonshire area forming their most northerly possession. The Catuvellauni were in turn conquered by the Romans in 43 AD.

The Roman road of Watling Street passed through the county, and an important Roman settlement, Lactodurum, stood on the site of modern-day Towcester. There were other Roman settlements at Northampton, Kettering and along the Nene Valley near Raunds. A large fort was built at Longthorpe.

After the Romans left, the area eventually became part of the Anglo-Saxon kingdom of Mercia, and Northampton functioned as an administrative centre. The Mercians converted to Christianity in 654 AD with the death of the pagan king Penda. From about 889 the area was conquered by the Danes (as at one point almost all of England was, except for Athelney marsh in Somerset) and became part of the Danelaw – with Watling Street serving as the boundary – until being recaptured by the English under the Wessex king Edward the Elder, son of Alfred the Great, in 917. Northamptonshire was conquered again in 940, this time by the Vikings of York, who devastated the area, only for the county to be retaken by the English in 942. Consequently, it is one of the few counties in England to have both Saxon and Danish town-names and settlements.

The county was first recorded in the Anglo-Saxon Chronicle (1011), as Hamtunscire: the scire (shire) of Hamtun (the homestead). The "North" was added to distinguish Northampton from the other important Hamtun further south: Southampton – though the origins of the two names are in fact different.

Rockingham Castle was built for William the Conqueror and was used as a Royal fortress until Elizabethan times. In 1460, during the Wars of the Roses, the Battle of Northampton took place and King Henry VI was captured. The now-ruined Fotheringhay Castle was used to imprison Mary, Queen of Scots, before her execution.

During the English Civil War, Northamptonshire strongly supported the Parliamentarian cause, and the Royalist forces suffered a crushing defeat at the Battle of Naseby in 1645 in the north of the county. King Charles I was imprisoned at Holdenby House in 1647.
