Northamptonshire Police (colloquially known as Northants Police) is the territorial police force responsible for policing the county of Northamptonshire in the East Midlands of England, in the United Kingdom. The Northampton Police area includes Brackley, Burton Latimer, Corby, Daventry, Desborough, Higham Ferrers, Irthlingborough, Kettering, Northampton, Oundle, Raunds, Rothwell, Rushden, Towcester, Thrapston and Wellingborough across 914 square miles (2,370 km2) with a resident population of 710,000. It responds to more than one million phone calls a year, with more than 120,000 of these being emergency 999. History Prior to the establishment of uniformed police forces in the United Kingdom, each parish had a Parish Constable – a person appointed locally who had responsibility for enforcing the law within their own village. In villages and towns, a system known as Watch and Ward was employed, where paid Watchmen guarded towns at night. Northamptonshire Police can trace its earliest roots to 1840 when the Northamptonshire Constabulary and Daventry Constabulary were formed. The establishment of police forces at that time was based upon principles established by Sir Robert Peel, the Home Secretary in 1822 and founder of modern-day policing in most Westminster-based systems of government. Known as the Peelian Principles, they describe a philosophy that define an ethical police force and include: Every police officer should be issued an identification number, to assure accountability for his actions. Whether the police are effective is not measured on the number of arrests, but on the lack of crime. Above all else, an effective authority figure knows trust and accountability are paramount. Hence, Peel's most often quoted principle that "The police are the public and the public are the police". Upon creation, Northamptonshire Constabulary initially started with seven superintendents and 35 police constables, who worked in a primitive shift system and were paid 12 shillings a week. In 1930, Northamptonshire Constabulary rolled-out their first motorised vehicles for law enforcement use. The inventory included two cars and four motorcycles for police officer use. The vehicles were stationed throughout the county, with one car based in Daventry and the other in Kettering. The motorcycles were stationed in Northampton, Wellingborough, Oundle and Towcester. The Northamptonshire Constabulary merged with the borough police forces within Northamptonshire on 1 April 1966 to form Northampton and County Constabulary with an estimated 442 officers and actual strength of 387. The force was renamed the Northamptonshire Police on 1 January 1975. Chief constables The chief constable
