Oldham, United Kingdom

The earliest known evidence of a human presence in what is now Oldham is attested by the discovery of Neolithic flint arrow-heads and workings found at Werneth and Besom Hill, implying habitation 7–10,000 years ago. Evidence of later Roman and Celtic activity is confirmed by an ancient Roman road and Bronze Age archaeological relics found at various sites within the town. Placenames of Celtic origin are still to be found in Oldham: Werneth derives from a Celtic personal name identical to the Gaulish vernetum, "alder swamp", and Glodwick may be related to the modern Welsh clawdd, meaning "dyke" or "ditch". Nearby Chadderton is also pre-Anglo-Saxon in origin, from the Old Welsh cadeir, itself deriving from the Latin cathedra meaning "chair". Although Anglo-Saxons occupied territory around the area centuries earlier, Oldham as a permanent, named place of dwelling is believed to date from 865, when Danish invaders established a settlement called Aldehulme.

From its founding in the 9th century until the Industrial Revolution, Oldham is believed to have been little more than a scattering of small and insignificant settlements spread across the moorland and dirt tracks that linked Manchester to York. Although not mentioned in the Domesday Book, Oldham does appear in legal documents from the Middle Ages, invariably recorded as territory under the control of minor ruling families and barons. In the 13th century, Oldham was documented as a manor held from the Crown by a family surnamed Oldham, whose seat was at Werneth Hall. Richard de Oldham was recorded as lord of the manor of Werneth/Oldham (1354). His daughter and heiress, Margery (d.1384), married John de Cudworth (d.1384), from whom descended the Cudworths of Werneth Hall who were successive lords of the manor. A Member of this family was James I's Chaplain, Ralph Cudworth (father of the Cambridge Platonist philosopher Ralph Cudworth). The Cudworths remained lords of the manor until their sale of the estate (1683) to Sir Ralph Assheton of Middleton.

Much of Oldham's history is concerned with textile manufacture during the Industrial Revolution; it has been said that "if ever the Industrial Revolution placed a town firmly and squarely on the map of the world, that town is Oldham." Oldham's soils were too thin and poor to sustain crop growing, and so for decades prior to industrialisation the area was used for grazing sheep, which provided the raw material for a local woollen weaving trade.

By 1756, Oldham had emerged as a centre of the hatting industry in England. The rough felt used in the production process is the origin of the term "Owdham Roughyed" a nickname for people from Oldham. It was not until the last quarter of the 18th century that Oldham changed from being a cottage industry township producing woollen garments via domestic manual labour, to a sprawling industrial metropolis of textile factories. The climate, geology, and topography of Oldham were unrelenting constraints upon the social and economic activities of the human inhabitants. At 700 feet (200 m) above sea level and with no major river or visible natural resources, Oldham had poor geographic attributes compared with other settlements for investors and their engineers. As a result, Oldham played no part in the initial period of the Industrial Revolution, although it did later become seen as obvious territory to industrialise because of its convenient position between the labour forces of Manchester and southwest Yorkshire.

Cotton spinning and milling were introduced to Oldham when its first mill, Lees Hall, was built by William Clegg in about 1778, the beginning of a spiralling process of urbanisation and socioeconomic transformation. Within a year, 11 other mills had been constructed, and by 1818 there were 19 – not a large number in comparison with other local settlements. Oldham's small local population was greatly increased by the mass migration of workers from outlying villages, resulting in a population increase from just over 12,000 in 1801 to 137,000 in 1901. The speed of this urban growth meant that Oldham, with little pre-industrial history to speak of, was effectively born as a factory town.

Oldham became the world's manufacturing centre for cotton spinning in the second half of the 19th century. In 1851, over 30% of Oldham's population was employed within the textile sector, compared to 5% across Great Britain. It overtook the major urban centres of Manchester and Bolton as the result of a mill building boom in the 1860s and 1870s, a period during which Oldham became the most productive cotton-spinning town in the world. In 1871, Oldham had more spindles than any country in the world except the United States, and in 1909, was spinning more cotton than France and Germany combined. By 1911 there were 16.4 million spindles in Oldham, compared with a total of 58 million in the United Kingdom and 143.5 million in the world; in 1928, with the construction of the UK's largest textile factory Oldham reached its manufacturing zenith. At its peak, there were more than 360 mills, operating night and day;
