Northamptonshire (//; abbreviated Northants.), archaically known as the County of Northampton, is a county in the East Midlands of England. In 2015 it had a population of 723,000. The county is administered by Northamptonshire County Council and by seven non-metropolitan district councils. It is known as "The Rose of the Shires".
Covering an area of 2,364 square kilometres (913 sq mi), Northamptonshire is landlocked between eight other counties: Warwickshire to the west, Leicestershire and Rutland to the north, Cambridgeshire to the east, Bedfordshire to the south-east, Buckinghamshire to the south, Oxfordshire to the south-west and Lincolnshire to the north-east – England's shortest administrative county boundary at 19 metres (20 yards). Northamptonshire is the southernmost county in the East Midlands region.
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.
