Cambridgeshire is one of the forty-seven counties of England, United Kingdom, with capital in Cambridge. Located in the East boundary region north with Lincolnshire, east with Norfolk and Suffolk, south with Essex and Hertfordshire, and west with Bedfordshire and Northamptonshire, occupies an area of 3389 km² and its population in 2011 was 806 700 habs. Although the majority of the land of the county is very low, the highest point is located in the locality of Great Chishill with a height of 146 ms s. N. M. Other high hills are Little Trees Hill and Wandlebury Hills. The current county is the product of different unifications made by the local government.
In 1888, when the county councils were established, two administrative divisions were established in this county: one in the south, around Cambridge, and another on the Isle of Ely. In 1965, these two divisions merged to form "Cambridgeshire and the Isle of Ely". In 1974 they were joined Huntingdon and Peterborough to form the current county of Cambridgeshire. Since 1998, the city of Peterborough is administratively separate from the county and forms a unitary authority. However, it is still associated with Cambridgeshire for different issues such as the police or the fire department. Two famous characters born in the county of Cambridgeshire are the politician and military Oliver Cromwell and the former British Prime Minister John Major.
