Blackwood (Welsh: Coed Duon or Coed-duon ⓘ) is a town, community and an electoral ward on the Sirhowy River in the South Wales Valleys administered as part of Caerphilly County Borough.

Deplorable working conditions at the time of the Industrial Revolution, however, led to Blackwood becoming a centre of the Chartist movement in the 1830s.

Upon meeting their comrades from the upper Sirhowy Valley the rebels armed themselves with makeshift weapons and marched south to Newport to demand the adoption of the People's Charter and the release of Henry Vincent from Monmouth gaol.

However, the South Wales Movement were the only ones to march and the national rising failed and its leaders were sentenced to death (later commuted to deportation to Tasmania).

In 1912 the Titanic's distress signals were picked up by amateur wireless enthusiast Artie Moore[3] who resided at the Old Mill, Gelligroes, just outside the town.

Evan James (Ieuan ap Iago, 1809–93) was a weaver and wool merchant by profession and owner of the Ancient Druid Inn in Hollybush, in the parish of Bedwellty, Monmouthshire.

The decline of the coal mining industry throughout the later part of the twentieth century affected South Wales, the major source of employment was lost and the landscape left daily reminders of what had been.

The bridge is a part of the Sirhowy Enterprise Way, regeneration project and opened four months ahead of schedule on 3 December 2005.

Difficulties with mining-related subsidence during construction and in the foreseeable future led the design team to allow the bridge to breathe if settlement does occur.

A statue to honour the Chartist struggle and their march to Newport has been erected on the East side of the bridge while a name plate is situated on the West.

In 1925 a Snooker Hall was opened, by the Coal Industry and the Social Welfare Organisation, and funded by the miners of Oakdale Colliery at the rate of 3d a week.

Programmes from the time included Tea Dances, snooker/billiards, reading groups, rehearsals and union meetings for local miners.

With the decline of the mining industry the building fell into disrepair throughout the 1970s and 1980s and ownership was handed to Islwyn Borough Council with the mandate to make it available for community use.

The 1904–1905 Welsh Revival, and the prominence of Christianity in the culture of Blackwood and the surrounding villages, have left the town with a large number of active and disused churches and chapels.

Mineral traffic to coal yards at Blackwood & Tredegar continued until April 1969 with track lifted the following year.

During the Covid 19 lockdowns the club ceased to meet in person but still managed to raise charitable funds via social media.

Additionally one club member completed a virtual walk from Land's End to John O Groats, raising over £4,000.00 for the cancer breast care unit at Ystrad Mynach hospital.
