This was bad for the local economy, which had come to rely upon supplying the fortress with beef and grain, and imported items such as oysters from the coast. The Romans had intermarried with local women and many auxiliary veterans had settled on farms locally.

Elizabethan period, but it did not survive beyond the early 1640s at the latest. In 1754, it was recorded that the valley was almost entirely populated by shepherds. Farm produce was traded at a number of markets and fairs, notably the Waun Fair above
Dowlais.
[The Welsh Academy Encyclopedia of Wales. Cardiff: University of Wales Press 2008.]
The Industrial Revolution
Influence and growth of iron industry

Merthyr was close to reserves of iron ore, coal, limestone, timber and water, making it an ideal site for ironworks. Small-scale iron working and coal mining had been carried out at some places in South Wales since the Tudor period, but in the wake of the
Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going f ...
the demand for iron led to the rapid expansion of Merthyr's iron operations. By the peak of the revolution, the districts of Merthyr housed four of the greatest ironworks in the world:
Dowlais Ironworks,
Plymouth Ironworks,
Cyfarthfa Ironworks and
Penydarren.
The companies were mainly owned by two dynasties, the

families.
Starting in the late 1740s, land within the Merthyr district was gradually being leased for the smelting of iron to meet the growing demand, with the expansion of smaller furnaces dotted around South Wales.
By 1759, with the management of John Guest, the Dowlais Ironworks was founded. This would later become the Dowlais Iron Company and also the first major works in the area. Following the success at Dowlais, Guest took a lease from the Earl of Plymouth which he used to build the Plymouth Ironworks.
However, this was less of a success until the arrival in 1763 of a "Cumberland ironmaster,
Anthony Bacon, who leased an area of eight miles by five for £100 a year on which he started the Cyfarthfa Ironworks and also bought the Plymouth Works".
After the death of Anthony Bacon in 1786, the ownership of the works passed to Bacon's sons, and was divided between Richard Hill, their manager and
Richard Crawshay
Richard Crawshay (1739 – 27 June 1810) was a London iron merchant and then South Wales ironmaster; he was one of ten known British millionaires in 1799.
Early life and marriage
Richard Crawshay was born in Normanton in the West Riding ...
. Hill now owned the Plymouth Iron Works and Crawshay the works at Cyfarthfa. The fourth ironworks was
Penydarren, built by
Francis Homfray and his son
Samuel Homfray in 1784.
It was the need to export goods from Cyfarthfa that led to the construction of the
Glamorganshire Canal running from their works right down the valley to Cardiff Bay, stimulating other businesses along the way.

During the first few decades of the 19th century, the ironworks at Cyfarthfa (and neighbouring Dowlais) continued to expand, and at their height were the most productive ironworks in the world: 50,000 tons of rails left just one ironworks in 1844, for the railways across Russia to Siberia. With the growing industry in Merthyr, several railway companies established routes linking the works with ports and other parts of Britain. They included the Brecon and Merthyr Railway,
Vale of Neath Railway,
Taff Vale Railway and
Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London

. They often shared routes to allow access to coal mines and ironworks through rugged country, which presented great engineering challenges. According to David Williams, in 1804, the world's first railway steam locomotive, "The Iron Horse", developed by the Cornish engineer
Richard Trevithick, pulled 10 tons of iron with passengers on the new
Merthyr Tramroad from Penydarren to
Quakers Yard.
He also claims that this was the "first 'railway' and the work of George Stephenson was merely an improvement upon it".
A replica of this locomotive is in the
National Waterfront Museum in Swansea. The tramway passed through what is arguably the oldest railway tunnel in the world, part of which can be seen alongside Pentrebach Road at the lower end of the town. The demand for iron was also fuelled by the Royal Navy, which needed cannon for its ships, and later by the railways. In 1802,

visited Merthyr to witness cannon being made.
Famously, upon visiting Merthyr in 1850,
Thomas Carlyle wrote that the town was filled with such "unguided, hard-worked, fierce, and miserable-looking sons of Adam I never saw before. Ah me! It is like a vision of Hell, and will never leave me, that of these poor creatures broiling, all in sweat and dirt, amid their furnaces, pits, and rolling mills."
Living conditions in the China district
China was the name given to a nineteenth-century slum in the Pont-Storehouse area of Merthyr Tydfil. This was not a '
Chinatown' in the modern sense, and its residents were mainly English, Irish and Welsh. The inhabitants of China were seen as a separate class, away from the respectable areas of Merthyr, and were clearly recognisable by their lifestyle and appearance. In his article, ''In search of the Celestial Empire'', historian Keith Strange compares China to areas of Liverpool, Nottingham and Derby, and states that this area was just as bad if not worse than those "little Sodoms".
There were at least 1,500 people living in the slum, the inhabitants of which were the poorest of society and had a bad reputation. Their living conditions were some of the most squalid in Britain. The slum was based around narrow streets, badly ventilated and full of crowded houses that led to festering diseases. China became known as "Little Hell" and was notorious for having no toilets but open sewers, which caused diseases such as
cholera and
typhoid.
The Merthyr Rising
With the
Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going f ...
came a sharp decline in young men working in agriculture, who were attracted by higher wages paid in industries such as iron. In 1829, the depression hit Merthyr hard, as ironmasters responded with dismissals, wage cuts and short-term working. Any sudden downturn in the market plunged workers into hardship, widening the class distinctions.
The
Merthyr Rising of 1831 was precipitated by ruthless collection of debts, frequent wage reductions, and imposition of
truck shops. Some workers were paid in specially minted coins or credit notes known as "truck", which could be spent only at shops owned by their employers. Many workers objected to the price and quality of goods sold there. Throughout May 1831, the coal miners and others who worked for
William Crawshay took to the streets of Merthyr Tydfil, calling for reform, and protesting against the lowering of their wages and general unemployment.
Between 7,000 and 10,000 workers marched, and for four days magistrates and ironmasters were under siege in the Castle Hotel, with the protesters effectively controlling the town. Soldiers called in from
Brecon clashed with the rioters, and several on both sides were killed. Despite the hope of negotiating with the owners, the skilled workers lost control of the movement. Several supposed leaders of the riots were arrested. One of them, Richard Lewis, popularly known as
Dic Penderyn, was hanged for stabbing a soldier in the leg, becoming known as the first local working-class martyr. It was claimed in 1876 that it was not Lewis who stabbed Black, but another man, Ianto Parker, who fled to America after the incident to avoid prosecution. Such claims have never been fully verified, although Lewis's innocence is widely accepted in Merthyr.
The Chartist movement of 1831 did not consider the reforms put forward by
The Reform Act of 1832 to be extensive enough.
The decline of coal and iron

The population of Merthyr reached 51,949 in 1861, but then went into decline for several years. As the 19th century progressed, Merthyr's inland location became increasingly disadvantageous for iron production. Penydarren closed in 1859 and Plymouth in 1880; thereafter some ironworkers migrated to the United States or even

status in 1908.
A prime example of the decline is the Cyfarthfa Ironworks. The actions, or inactions, of
Robert Crawshay ("The Iron King") can be seen as the main reasons for its downfall. The Crawshays refused to modernise by replacing iron production with steel production, using the newly discovered
Bessemer process. This led to closure of the works in 1874, which caused economic hardship and unemployment in Merthyr.

After Robert's death in 1879 his son William Thompson Crawshay took over the Cyfarthfa works. William finally modernised the works, introducing steel production. However it took until 1882 to get the works back up and running. It never fully caught up with other steel-making areas and closed again in 1910. Despite a comeback during the
First World War

, it finally closed in 1919. The local steel and coal industries began to decline after the war. By 1932, more than 80 per cent of men in
Dowlais were unemployed; 27,000 people emigrated from Merthyr in the 1920s and 1930s, and a Royal Commission recommended that the town's county borough status be withdrawn. The fortunes of Merthyr revived temporarily during World War II, as war industry reached the area.

was built in the same factory.
Hoover and other companies targeted Merthyr, and its declining coal and iron industries gave space for new businesses to start up there and grow. There were then increasing numbers of unemployed workers in the area, and since the Second World War this has included women too. "Initially 350 people were employed, by the mid 1970s that number had risen to near 5,000; making Hoover the largest employer in the borough", and therefore strongly filling in for the declining coal and iron industries.
The strong growth of employment of women in Merthyr after the Second World War can be seen as a result of the introduction of more light manufacturing and consumer-based business – a stark contrast to the heavy industry in the coal and ironworks which had an almost entirely male workforce.
Several other companies built factories, including the aviation components company Teddington Aircraft Controls, which opened in 1946 and closed in the early 1970s. The Merthyr Tydfil Institute for the Blind, founded in 1923, is the oldest active manufacturer in the town.

Industrial legacy
Despite Merthyr's long and varied
industrial heritage, much of it has declined, with the closure of long-established nearby
collieries, and
steel and ironworks. Despite improvements, some parts remain economically disadvantaged and a marked proportion of the community are still long-term
unemployed. In 2006, a

Religion
Anglican churches

Merthyr was regarded as a
nonconformist stronghold in the 19th century, but the chapels declined rapidly from the 1920s onwards and most are now closed.
The Church of England (now the Church in Wales) sought to counterbalance the influence of nonconformity in the 19th century and Merthyr had a succession of notable parish priests. Among them was
John Griffith, rector of Merthyr from 1858 until his death in 1885. Griffith had previously been the incumbent at
Aberdare, where he had created controversy for his evidence to the commissioners preparing the
1847 Education Reports

. His views became more tempered over time. Griffith's move to Merthyr Tydfil saw him take over a much larger and more established parish than Aberdare. He became less than popular with the church authorities, however, as a result of his support for
disestablishment. In July 1883 he stated "I have been for years convinced that nothing but Disestablishment, the separation of the Church from the State, can ever reform the
Church in Wales."
Griffith's funeral was said to have been attended by 12,000–15,000 people. "I venture to declare," wrote one correspondent, "no man in this part of the kingdom could be more popular in his day and generation than the Rev. John Griffith." Among the nonconformist ministers present was an old rival, Dr
Thomas Price Thomas Price may refer to:

of Aberdare.
Another influential character was Sir
John Guest, who contributed greatly to the building of
St John's Church, Dowlais. Despite the generally small congregations of Anglican churches, St John's thrived: it held two services in English each Sunday and also two in Welsh. This church was significant in the plan to counterbalance nonconformity in Merthyr. In 2019 the church was converted into residential flats which retain the original structure.
Nonconformity
Merthyr was notable in the 19th and early 20th centuries for a large number of nonconformist places of worship, most holding services in Welsh.
One of the earliest was
Ynysgau Chapel, which dated from 1749. It was demolished in 1967 as part of the Merthyr Town Improvement Scheme.
The original cause at Ynysgau was established by various "
dissenters" from the Church of England.
It had been acquired by the Independents (
Congregationalists) by the early 19th century.
Other early chapels were Zion and Ebenezer (
Baptists), Zoar and
Bethesda (Independents) and Pontmorlais (
Calvinistic Methodists).
The Merthyr Hebrew Congregation
Merthyr Tydfil had the largest Jewish community in Wales in the 19th century, reaching 400 at its height.
As the Jewish population had increased, Merthyr Hebrew Congregation was founded in 1848 and a cemetery consecrated a few years later at Cefn-Coed.
Merthyr Synagogue was built in 1875. Religious services ceased when it had a male Jewish congregation of under ten, the
minyan (quorum) required for them.
In 1978 the building was given Grade II* listing, changed to Grade II in 1983. In the 1980s the 120-year-old synagogue was sold and became a Christian Centre, then a gym. In 2009 permission was obtained to turn it into flats. In 2019 it was bought by the Foundation for Jewish Heritage, which plans to open as a Jewish Heritage Centre in 2025.
Culture

The town's many cultural events include local poets and writers holding poetry evenings and
music festivals organised at
Cyfarthfa Castle
Cyfarthfa Castle ( cy, Castell Cyfarthfa; ) is a castellated mansion that was the home of the Crawshay family, ironmasters of Cyfarthfa Ironworks in Park, Merthyr Tydfil, Wales. The house commanded a view of the valley and the works, which ...
and Park.
Menter Iaith Merthyr Tudful (the Merthyr Tydfil Welsh Language Initiative) has successfully transformed the Zoar Chapel and adjacent vestry building in Pontmorlais into a community arts venue,
Canolfan Soar and Theatr Soar, which run a programme of performance events and activities in both Welsh and English, together with a cafe and a bookshop specialising in local interest and Welsh language books and CDs.
Merthyr Tydfil Housing Association, in partnership with Canolfan Soar, has raised funds to turn the Pontmorlais area into a cultural quarter. With references to the 1831
Merthyr Rising and red bricks for its frontage, an arts and creative industries centre named Redhouse Cymru was launched in
Merthyr Tydfil Town Hall on
Saint David's Day 2014. The town's several choirs – Dowlais Male Voice Choir, Ynysowen Male Voice Choir, Treharris Male Voice Choir, Merthyr Tydfil Ladies Choir, Con Voce, Cantorion Cyfarthfa, St David's Church Choir, St David's Choral Scholars, Merthyr Aloud and Tenovus – perform locally and abroad and in the media.
Merthyr has several historical and heritage groups:
*Merthyr Tydfil Heritage Regeneration Trust aims to preserve for the benefit of the residents... and the Nation at large whatever of the Historical, Architectural and Constructional Heritage may exist in and around Merthyr Tydfil in the form of buildings and artefacts of particular beauty or of Historical, Architectural or Constructional interest and also to improve, conserve and protect the environment thereto."
*Merthyr Tydfil Historical Society sets out "to advance the education of the public by promoting the study of the local history and architecture of Merthyr Tydfil".
*Merthyr Tydfil Museum and Heritage Groups aspire "to advance the education of the public by the promotion, support and improvement of the Heritage of Merthyr Tydfil and its Museums."
Merthyr's Central Library holds a prominent position in the town centre, as a
Carnegie library. Merthyr hosted the
National Eisteddfod in 1881 and 1901 and the national
Urdd Gobaith Cymru Eisteddfod in 1987. Like nearby
Aberdare, it is known for its music scene. Several bands have achieved national success, including
The Blackout and
Midasuno. From 2011 to 2014, the town held a Merthyr Rock Festival at Cyfarthfa Park. To complement this, the town holds the Merthyr Rising each year – a three-day celebration of town history through local music, held on the site of the Rising itself in Penderyn Square at the junction of Castle Street and High Street.

Transport
The "Pen-y-Darren" locomotive

In 1802, Homfray, the Master of the Penydarren Ironworks, commissioned engineer
Richard Trevithick to build one of his high-pressure steam engines to drive a
hammer at the Penydarren Ironworks. With the assistance of works engineer Rees Jones, Trevithick mounted the engine on wheels and turned it into a locomotive. In 1803, Trevithick sold the patents for his locomotives to Homfray.
Homfray was so impressed with Trevithick's locomotive that he made another bet with Crawshay, this time for 500
guineas, that it could haul 10
tons of iron along the
Merthyr Tydfil Tramroad from Penydarren to
Abercynon , a distance of . Amid great public interest, on 21 February 1804 it successfully carried 11.24 tons of coal, five wagons and 70 men over the full distance in 4 hours and 5 minutes, at an average speed of . As well as Homfray, Crawshay, and the passengers, other witnesses included Mr Giddy, a respected patron of Trevithick, and an "engineer from the Government". The latter was probably a safety inspector, who would have been particularly interested in the boiler's ability to withstand high steam pressures. This allowed others to develop Trevithick's ideas; some claim the modern railway system was born in Merthyr Tydfil. In modern Merthyr, behind the monument to Trevithick's locomotive, is a stone wall, the sole remainder of the former boundary wall of Penydarren House. There is a full-scale working replica of Trevithick's 1804 steam-powered railway locomotive in the
National Waterfront Museum, Swansea.
