The development of the Cardiff Docks played a major part in Cardiff's development by being the means of exporting coalfrom the SouthWales Valleys to the rest of the world, helping to power the Industrial Age. The coal mining industry helped fund the growth of Cardiff to become the capital city of Wales and contributed towards making the docks owner, The 3rd Marquess of Bute, the richest man in the world at the time. In 1794, the Glamorganshire Canal was completed, linking Cardiff with Merthyr, and in 1798 a basin was built, connecting the canal to the sea. Increasing agitation for proper dock facilities led Cardiff's foremost landowner, The 2nd Marquess of Bute, to promote the construction of the West Bute Dock, opened in October 1839. Just two years later, the Taff Vale Railway was opened. From the 1850s coal supplanted iron as the industrial foundation of South Wales, as the Cynon Valley and Rhondda Valley were mined. Well-appointed residential areas were created in the 1840s and early 1850s, centred around Mount Stuart Square and Loudoun Square to house the growing numbers of merchants, brokers, builders, and seafarers. As Cardiff's coal exports grew, so did its population; dockworkers and sailors from across the world settled in neighbourhoods close to the docks, known as Tiger Bay from the fierce currents around the local tidal stretches of the River Severn. Migrant communities from up to 45 nationalities, including Norwegian, Somali, Yemeni, Spanish, Italian, Caribbean, and Irish, helped to create the unique multicultural character of the area. Tiger Bay had a reputation for being a tough and dangerous area. Merchant seamen arrived in Cardiff from all over the world, only staying for as long as it took to discharge and reload their ships. Consequently, the area became the red-light district of Cardiff, and many murders and lesser crimes went unsolved and unpunished, as the perpetrators had sailed away. However, locals who lived and stayed in the area describe a far friendlier place. Exports reached 2 million tons as early as 1862, with the East Bute dock opening in 1859. In 1862, 2,000,000 tons of coal were exported from Cardiff Docks; by 1913, this had risen to 10,700,000 tons. Frustration at the lack of development at Cardiff led to rival docks' being opened at Penarth in 1865 and Barry in 1889. These developments eventually spurred Cardiff into action, with the opening of the Roath Dock in 1887 and the Queen Alexandra Dock in 1907. Coal exports from the South Wales Coalfield via Cardiff totalled nearly 9 million tons per annum, much of it exported in the holds of locally owned tramp steamers. The wealthier residents were able to move away to the new Cardiff suburbs. Butetown became crowded, as families took in lodgers and split up the three-storey houses to help pay the rents. By 1932, in the depths of the Great Depression which followed the 1926 United Kingdom general strike, coal exports had fallen to below 5 million tons, and dozens of locally owned ships were laid-up. It was an era of depression from which Cardiff never really recovered, and despite intense activity at the port during the Second World War, coal exports continued to decline, finally ceasing in 1964.
Popular culture
The name "Tiger Bay" was applied in popular literature and slang to any dock or seaside neighbourhood which shared a similar notoriety for danger.
Tiger Bay Youth run football teams for all age groups in the South of Cardiff.
Cardiff Bay
In 1999, the area was redeveloped by the Cardiff Bay Development Corporation. This redevelopment focused around the building of the Cardiff Bay Barrage, one of the most controversial building projects of the day but also one of the most successful, that impounds the Rivers Taff and the Ely to create a massive freshwater lake. This resulted in the equally controversial renaming of the area to "Cardiff Bay".
