Lancashire ( /ˈlæŋkəʃər/ or, less commonly, /ˈlæŋkəʃɪər/) is a non-metropolitan county of historic origin in the North West of England. It takes its name from the city of Lancaster, and is sometimes known as the County of Lancaster. Although Lancaster is still considered to be the county town, Lancashire County Council is based in Preston. Lancashire is sometimes referred to by the abbreviation Lancs, as originally used by the Royal Mail. The population of the county is 1,449,700. People from the county are known as Lancastrians.

The history of Lancashire is thought to have begun with its founding in the 12th century. In the Domesday Book (1086), some of its lands had been treated as part of Yorkshire. The land that lay Inter Ripam et Mersam, "between the Ribble and Mersey", formed part of the returns for Cheshire. Once its initial boundaries were established, it bordered Cumberland, Westmorland, Yorkshire and Cheshire.

Lancashire emerged during the Industrial Revolution as a major commercial and industrial region. The county encompassed several hundred mill towns and collieries. By the 1830s, approximately 85% of all cotton manufactured worldwide was processed in Lancashire.Preston, Accrington, Blackburn, Bolton, Rochdale, Oldham, Chorley, Darwen, Nelson, Colne and Burnley were major cotton mill towns during this time. Blackpool was a major centre for tourism for the inhabitants of Lancashire's mill towns, particularly during wakes week.

Sarah Lancashire (born 10 October 1964 in Oldham, Lancashire) is an English actress, probably best recognised for her role as Raquel Watts in Coronation Street. She graduated from the Guildhall School of Music and Drama in 1986.

Lancashire's first recurring television role is still her best known. She played barmaid Raquel Watts in the ITV1 soap opera Coronation Street from 1991 to 1996, reappearing for one last episode in 1999. Raquel was a sweet, if somewhat dippy character, who was a firm favourite with viewers of the long running show. She had previously appeared on the programme in November 1987 playing Wendy Farmer.

After leaving Coronation Street, rather than struggle to find work in other shows after playing such a well known character (a fate that has befallen many soap opera actors), Lancashire worked in a number of high profile series. From 1997 to 1999 she played Ruth Goddard in the ITV1 drama series Where The Heart Is, and in 1999 she appeared in the BBC sitcom Murder Most Horrid, which also starred comedienne Dawn French.

Nicola Walker (born 1970) is an English actress, best known for her starring roles in various British television programmes from the 1990s onwards, particularly as Ruth Evershed in the spy drama Spooks. She has also worked in theatre, radio and film.

Born in Stepney in the East End of London, she has an older brother. Walker attended Forest School, Walthamstow, and undertook acting classes from aged 12 to speak to boys. Walker then attended New Hall, Cambridge, where she started her acting career with the Cambridge Footlights. Her contemporaries included Spooks writer David Wolstencroft and comedienne Sue Perkins, who were all part of the 1990 national tour.

Offered a place at RADA, on graduation from Cambridge she already had some roles and an agent, so decided to pursue her career. Based in London, she shared a flat with Perkins, Sarah Phelps and Emma Kennedy, acting at the Edinburgh Festival and the London Festival Fringe.

Her first major television roles were in 1997, as Gypsy Jones in Channel 4's adaptation of A Dance To The Music Of Time, and as English teacher Suzy Travis in two series of Steven Moffat's school-based sitcom Chalk. She has also appeared in guest roles in episodes of series such as Dalziel and Pascoe, Jonathan Creek, Pie in the Sky and Broken News.
