The traditional settlement pattern remained the same until the 19th Century. Marsden itself was no more or less important than any of the scattered farmsteads in the hills.
In 1801 a quarter of the English population was urban. By the end of the 19th Century England became the first country in the history of the world to have most of its population living in towns. Immigration from Scotland and Ireland and a staggering rate of reproduction meant that a population of 9 million in 1801 went to 18 million in 1851 then to 36 million by 1911.
From "The Making of the English" by Jeremy Paxman
Queen Elizabeth sold the manor of Marsden to one Edward Jones, for £29. Later, the manor passed to the Greenwoods, and by the 18th Century, it was owned by the Radcliffe family.
The 19th century was a period of massive change. The population expanded to work in the many new textile mills, mainly living in Marsden village in terraced housing. The Colne valley became the heart of the country's woollen textile industry.
In 1841 there were 474 inhabited houses in Marsden; in 1901 there were 968.
