Prehistory There is little evidence of prehistoric settlement in the
Blakewater valley, in which Blackburn developed. Evidence of activity in the form of two urn burials has been discovered from the
Bronze Age in the hills around Blackburn. In 1879, a
cinerary urn was discovered at a
tumulus at Revidge, north of the town; another was excavated in 1996 at Pleasington Cemetery, west of the town, by gravedigger Grant Higson. The presence of a
sacred spring—perhaps in use during the
Iron Age—provides evidence of prehistoric activity in the town centre, at All Hallows Spring on Railway Road.
Roman era Blackburn is located where a
Roman military road crossed the river Blakewater. The road linked
Bremetennacum Veteranorum (
Ribchester) and
Mamucium (a major Roman
fort that occupied
Castlefield in Manchester). The route of the road passed east of
Blackburn Cathedral and probably crossed the river in the Salford neighbourhood just east of the modern town centre. It is not clear whether the road predated the settlement. George C. Miller, in his
Blackburn: The Evolution of a Cotton Town, said: The ancient military way from
Mamucium (Manchester) to (
Bremetennacum) (Ribchester), passing over Blacksnape, plunges on its unswerving course through Blackamoor, over the scarp at Whinney Heights, to pass across the Blakewater in the vicinity of Salford. This fact alone presents a reasonable argument for the existence of a British oppidum or walled village on the site, it being customary for such primitive communities to cluster in the vicinity of a ford or bridge. According to William Abram (1877): The Parish of Blackburn contains many interesting vestiges. Three of the four principal roads constructed by the Romans in Lancashire traversed some portion of the Parish : —I. The lower road from the south to Carlisle, intersected the township of Walton-in-le-Dale. 2. The road from Manchester to Overborough crossed the Parish at its broadest part. 3. The road from the sea to the interior, which formed the conmiunication between the "Sistuntian Port" (on the Wyre) and Ribchester, Ilkley-in-Wharfedale, Aldborough andYork, enters Blackburn Parish at Ribchester, by a ford over the Ribble. The late Rev. E. Sibson, in a paper on the Roman Roads of the Wigan district, speaks of a road of this kind which branched off eastward from Blackrod, "Street-fold and Water-street, near Rivington, and by White Hough, in Tockholes, to the small Roman station at Blackburn, near the new road to Preston."
Roman temple spring at All Hallows All Hallows Spring was excavated by
Antiquarians in 1654 and found to contain an inscribed stone commemorating the dedication of a temple to
Serapis by Claudius Hieronymus,
legate of
Legio VI Victrix.
Middle Ages of
cotton mill workers in 1920 in Cowell Street in the Nab Lane area Christianity is believed to have come to Blackburn by the end of the 6th century, in either 596 (as there is a record of a "church of Blagbourne" in that year) or 598 AD. The town was important during the
Anglo-Saxon era when the
Blackburnshire Hundred came into existence as a territorial division of the kingdom of
Northumbria. The manor came into the possession of Henry de Blackburn, who divided it between his two sons. Later, one half was granted to the monks of
Stanlow Abbey and this
moiety was subsequently granted to the monks of
Whalley Abbey. During the 12th century, the town's importance declined as
Clitheroe became the regional centre. From the mid-18th to the early 20th century Blackburn evolved from a small market town into "the weaving capital of the world", and its population increased from less than 5,000 to over 130,000. ''John Bartholomew's Gazetteer of the British Isles'' provides a profile of Blackburn in 1887: Blackburn.

calico,
muslin, &c., there being over 140 mills at work. There are also factories for making cotton machinery and
steam-engines. Blackburn has been associated with many improvements in the manufacture of cotton, among which was the invention (1767) of the "
spinning jenny" which was invented in nearby
Oswaldtwistle by
James Hargreaves, who died in 1770. There are several fine churches and public buildings. A
Corporation Park (50
acres in area) is on the outskirts of the town. Several lines of railway converge here, passing through one principal station belonging to the Lancashire and Yorkshire Rly. Co. Bl. returns two members to Parliament. at
Queen Street Mill Textile Museum, Burnley From around 1750, cotton textile manufacturing expanded rapidly. Supplied with cotton by merchants, and paid by the piece, cottagers spun cotton into thread and wove it into cloth. The merchants arranged for cloth to be bleached and dyed. After 1775,
spinning mills were built in the town. Early mills were warehouse conversions; the first purpose-built spinning mill was constructed in 1797 and by 1824 there were 24. The number of
spindles reached 2.5 million by 1870 and spinning mills were constructed up to that time – 24 since 1850. Spinning declined between 1870 and 1900 as the sector transferred to south Lancashire. In 18th-century Blackburn,
weaving was primarily undertaken by
handloom weavers working from their own cottages. However, as powerlooms were introduced into the mills after 1825, the percentage of handloom weavers began to decline and this occurred more rapidly in areas closer to the town. In 1826 the
Power-loom riots cam through Blackburn in response to the loss of jobs and low wages. Handloom weavers continued to make up a sizeable portion of the workforce in outlying rural areas. The last handloom shop in Blackburn closed in 1894.
1800s In 1807, the
Daniel Thwaites & Co brewery was established; the company is still in business today and is now based at Sykes Holt in Mellor. Improvements to the
power loom in the early 1840s, and the construction of a railway line in 1846, led to greater investment in power looms in Blackburn in the second half of that decade. The railway brought opportunities for expansion of the cotton trade, and in subsequent decades many new mills were constructed: between 1850 and 1870, sixty-eight weaving-only and four combined weaving/spinning mills were built and nine weaving mills were built per decade between 1870 and 1890. Improvements in power loom efficiency meant that weaving, the primary source of wealth and income for handloom weavers, began to transfer from the cottage industry to factories. This led to high rates of unemployment: according to figures published in March 1826, some 60% of all handloom weavers in Blackburn and
Rishton,
Lower Darwen and
Oswaldtwistle were unemployed. High unemployment led to the
Lancashire weavers' riots. At 3:00pm on 24 April 1826, a mob arrived in Blackburn after attacking power looms in
Accrington. Proceeding to Bannister Eccles' Jubilee Factory on Jubilee Street, the mob destroyed 212 power looms in the space of 35minutes. They then turned their attention to John Houghton and Sons' Park Place factory, located nearby, and destroyed another 25 looms, before seeking more machinery to attack. The crowd began to disperse at around 6:00pm, troops having arrived at 3:30pm to try to quell the rioting.
20th-century decline of the cotton industry In 1890, Blackburn's
Chamber of Commerce had recognised that the town was overly dependent on the cotton industry, warning of the dangers of "only having one string to their bow in Blackburn." The warning proved prophetic when, in 1904, a slump hit the cotton industry and other industries dependent on it, such as engineering, brewing and building. In 1908, another slump saw 43 mills stop production and a quarter of the town's looms lay idle. During the
First World War suspension of trade with India resulted in the expansion of colonial British India's cotton industry at the expense of Britain's, and the imposition of an 11% import tariff by the colonial British Government led to a dramatic slump in trade in 1921, a situation which worsened in 1922 after the Indian Government raised the tariff to 14%. This caused the number of stopped mills to increase to 47, with 43,000 looms lying idle. Two years into the slump, Foundry and Limbrick Mills became the first to close permanently. In 1928, there was another slump in textile production, and another strike in 1929 after employers requested a 12% wage cut; 40,000 cotton workers struck for a week and eight mills closed, making 28 closures in six years. A total of 26 mills closed down between 1930 and 1934. June Anne Devaney was a three-year-old patient at Queens Park Hospital when she was abducted from her cot and murdered in the hospital grounds on 15 May 1948. Fingerprints on a bottle underneath her cot led the police to fingerprint every male over the age of 16 who was present in Blackburn on 14 and 15 May 1948. After taking over 46,500 sets of fingerprints, a match was made with Peter Griffiths, a 22-year-old ex-serviceman. Griffiths admitted his guilt and his trial ascertained if he was sane or not. After deliberating for 23 minutes, the jury found him sane and he was hanged at
Liverpool Prison on Friday 19 November 1948. After his conviction, the police destroyed all fingerprints they had taken.
1948–1999 Between 1948 and 1950, the textile industry experienced a short post-war boom, during which sales increased, industry training methods improved and automatic looms were introduced, which allowed a single weaver to control 20 to 25 looms. Loom sheds were rebuilt to house new, larger looms. Despite the post-war boom, the cotton industry continued to decline and only 25% of the town's population were employed in textiles by 1951; this figure had stood at 60% up to the beginning of the
Great Depression in 1929. In 1952, the number of weavers fell from 10,890 to 9,020. By 1955 more cloth was imported from India than was exported By 1960, there were 30 mills operating in Blackburn. Closures continued in the 1960s with The Parkside, Fountains, Malvern and Pioneer Mills shutting in 1964. In 1967 the Eclipse Mill at Feniscowles closed, unable to compete with imported cloth sold at nine pence cheaper per yard than the mill could produce. By the end of that year there were 26 mills operating. The 1970s saw further closures,and the number of textile workers in Blackburn reduced to 6,000 by January 1975, the year in which the Albion and Alston mills stopped production with the loss of 400 jobs. In 1976, there were 2,100 looms in operation in the town, compared with 79,405 in 1907.
21st-century revitalisation After continued economic decline in the 2000s, new investment began in the 2010s. In 2015, Scottish designer
Patrick Grant rescued Cookson & Clegg, a factory founded in Blackburn in 1860 that was facing closure. The following year he launched the Blackburn-based clothing brand
Community Clothing to boost employment in British mills and factories. The inaugural British Textile Biennial, a month-long festival celebrating textiles through art and exhibitions, was held in Blackburn in 2019. The second edition took place in October 2021; it included an exhibition from Turner Prize winner
Lubaina Himid and a film starring
Maxine Peake. In 2021, the
Blackburn with Darwen Council proposed a £250million
Blackburn Master Plan to revitalise central Blackburn over the next decade, with the goal of building 500 new homes and creating 1,000 jobs. In 2022, £200million in government, council and private investments were announced for the revitalisations of the town centres in both Blackburn and Darwen. The Townscape Heritage Project will create a new cultural quarter in Blackburn's historic town centre. Councillor Phil Riley stated that additional investment over the next decade could lead to 100,000 jobs in the borough.
St Peter's Burial Ground During late 2015, work done on St Peter's Burial Ground in advance of road construction involved disinterring the remains of nearly 2,000 individuals buried there during the cemetery's period of operation (1821–1945). The burial ground had been connected with the former St Peter's Church, a large one that seated some 1,500 people, which was demolished in 1976. Archaeologists found that nearly half of the bodies were those of young children, who appeared to have died quickly during the mid-19th century from illnesses affected the lungs and gastrointestinal system. The numbers are taken as reflecting the massive increase in the city's population during that period due to its booming textile industry, which led to unhealthy living situations among the working classes. The remains were to be relocated to another section of the cemetery. A memorial service conducted by
Julian Henderson, the
Bishop of Blackburn, for those being reburied was scheduled to be held during the summer of 2016. ==Governance==
