Essex ( /ˈɛsɨks/) is a ceremonial and non-metropolitan county in the East of England, and one of the home counties. It is located to the northeast of Greater London. It borders with Cambridgeshire and Suffolk to the north, Hertfordshire to the west, Kent to the South and London to the south west. Essex County Council is the principal local authority for much of the county, sharing functions with twelve district councils. The county town is Chelmsford. The southern Essex boroughs of Thurrock and Southend-on-Sea are governed separately as unitary authorities. It was established in antiquity and formed the eastern portion of the Kingdom of Essex. Sections of the county closer to London are part of the Metropolitan Green Belt, which prohibits development. It is the location of the regionally significant Lakeside Shopping Centre and London Stansted Airport; and the new towns of Basildon and Harlow.

The name Essex originates in the Anglo-Saxon period of the Early Middle Ages and has its root in the Old English Ēastseaxe (i.e. the "East Saxons"), the eastern kingdom of the Saxons. Originally (in 527 AD) it occupied territory to the north of the River Thames, incorporating all of what later became Middlesex and most of what later became Hertfordshire, though its territory was later restricted to lands east of the River Lea.Colchester in the north east of the county is Britain's oldest recorded town, dating back to before the Roman conquest, when it was known as Camulodunum and was sufficiently well-developed to have its own mint. Subsequently the Kingdom of Essex was subsumed into the Kingdom of England and Essex eventually became a county.

David Essex OBE (born David Albert Cook on 23 July 1947) is an English musician, singer-songwriter and actor. Since the 1970s, Essex has attained nineteen Top 40 singles in the UK (including two number ones), and sixteen Top 40 albums. He has also had an extensive career as an actor performing on stage and screen.

Essex was born in Plaistow, which was at that time in Essex (hence his stage name), but now falls within the borders of Greater London. His father, Albert, was an East End dock worker and his mother, Olive (née Kemp), was a self-taught pianist and an Irish Traveller. His grandfather, Thomas Kemp, was named 'Philimore' which was the anglicised version of 'Philly Mor' - being Irish for 'Big Philly'. Essex was two years old when his parents moved out of the overcrowded home the family was sharing with relatives, to Canning Town where he grew up. Essex attended Star Lane Primary School, he loved playing football and did not answer any of the questions in the Eleven plus exam for entry into a Grammar School, so that he could ensure he attended Shipman County Secondary School where he knew they played the game. He was also a member of West Ham United Juniors for a while and dreamed of one day being a professional player. He then also became interested in music and played drums with a local band, before becoming a singer.
