Cambridgeshire (abbreviated Cambs.) is a county in England, bordering Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The city of Cambridge is the county town.
Modern Cambridgeshire was formed in 1974 as an amalgamation of the counties of Cambridgeshire and Isle of Ely and Huntingdon and Peterborough, which had been created in 1965 from the historic counties of Cambridgeshire, Huntingdonshire, the Isle of Ely and the Soke of Peterborough.
