Lancashire is a county on the north-west coast of England which dates back to the 12th century. The population today is around 1,500,000 and the county town, from which it derives its name, is Lancaster. Its most famous symbol is the Red Rose of Lancaster, dating back to the fifteenth century Wars of the Roses, the civil wars in which the House of Lancaster and the House of York (a white rose) fought over the throne of England. In the 19th century, Lancashire was a major centre of industry, in particular due to its wealth of cotton mills – in the 1830s, 85% of all cotton manufactured across the world was produced in Lancashire. Blackpool was also a popular seaside resort for holiday-makers from the mill towns. Increasingly urbanised during the 20th century, Lancashire’s population almost trebled between 1871 and the present day, and it remains a largely industrial county, although also experiences tourism due to its rich cultural traditions and historical heritage.
