1922 Urdd Gobaith Cymru is founded

Urdd Gobaith Cymru, literally, the Welsh League of Hope, but normally translated as the Welsh League of Youth, is a Welsh-medium youth movement. The Urdd is Wales's largest youth organisation and it was founded in 1922 by Sir Ifan ab Owen Edwards. The first Urdd local branch was established in Treuddyn in 1922. The logo of the Urdd is a triangle of green (symbolising Wales), red (symbolising fellow-man), and white (symbolising Christ). In 1925 the first "Peace and Goodwill Message" from the youth of Wales to the youth of the world was issued by the Urdd, a custom that continues every year on 18 May.

1902 Opening of Great Orme

The Great Orme (Welsh - Y Gogarth or Pen y Gogarth) is a prominent limestone headland on the north coast of Wales, next to the town of Llandudno. It is echoed by the Little Orme, a smaller but very similar limestone headland on the eastern side of Llandudno Bay in the parish of Llanrhos. Its English name derives from the Viking (Old Norse) word for sea serpent. The Great Orme being the head, with its body being the land between the Great and Little Ormes. Although the Vikings left no written texts of their time in North Wales, they certainly raided the area though they appear to have not founded any permanent settlements.

1894 Mining disaster at Albion Colliery

Cilfynydd is a village in the county borough of Rhondda Cynon Taf, a mile from the South Wales Valleys town of Pontypridd, and 13 miles north of the capital city, Cardiff. The Albion Steam Coal Co. began sinking a coal mine in 1884 at Ynyscaedudwg Farm. The Albion Colliery opened in August 1887, served by the Llancaiach Branch line of the Taff Vale Railway. Albion was the scene of the second worst disaster in the South Wales Coalfield, after the later disaster at the Universal Colliery at Senghenydd in 1913 (439 men are killed). Massive explosion caused by the ignition of coal dust following an explosion of firedamp killed 290 men and boys. Almost everyone in the community lost someone in the disaster.

1877 First soccer Welsh Cup

The Welsh Cup (Welsh - Cwpan Cymru) is a knock-out football competition contested annually by teams from Wales. The Football Association of Wales is the organising body of this competition. The Welsh Cup was first awarded in 1877 to Wrexham, who have won it a record 23 times. From 1996 to 2011, only clubs playing in the Welsh football league system were allowed to enter the Welsh Cup. This rule excluded the six Welsh clubs who played in the English football league system - Cardiff City, Colwyn Bay, Merthyr Tydfil Town, Newport County, Swansea City and Wrexham. In 2012, UEFA stated that Welsh clubs playing in the English football league system could not qualify for European competitions via the Welsh Cup but they could qualify via the English league and cup competitions, hence they were again excluded from the Welsh Cup.

1863 Spa built at Trefriw

Trefriw is today mostly known for its woollen mills, and for the nearby chalybeate spa. Its waters were one of very few throughout Europe to have been classified as a medicine due to their high iron content. In 1833 the old Roman mineral water caves (believed to have been discovered by soldiers of the XXth Roman Legion) were excavated in an attempt to attract people to them. In 1863 Lord Willoughby de Eresby built a small bath-house, replaced a decade later by the current building. In 2003, Nelsons purchased the Spa and the rights to the Spatone mineral water produced there. Today Spatone is sold around the world, with all packaging and manufacture on site in Trefriw.

1831 Merthyr Rising

The Merthyr Rising was the violent climax to many years of simmering unrest among the large working class population of Merthyr Tydfil and the surrounding area. The coal miners and others who worked for William Crawshay took to the streets, protesting against the lowering of their wages and general unemployment. For the first time in the world the red flag of revolution was flown. Twenty-six people were arrested and put on trial for taking part in the revolt. Several were sentenced to terms of imprisonment, others sentenced to penal transportation to Australia, and two were sentenced to death by hanging - Lewsyn yr Heliwr (known as Lewis Lewis) for robbery and Dic Penderyn (known as Richard Lewis) for stabbing a soldier in the leg with a seized bayonet.

1811 Presbyterian Church of Wales

The Presbyterian Church of Wales (Welsh - Eglwys Bresbyteraidd Cymru), also known as The Calvinistic Methodist Church, is a denomination of Protestant Christianity in Wales. It was born out of the Welsh Methodist revival and the preaching of Howell Harris and Daniel Rowland and seceded from the Church of England in 1811. Most of churches are in Wales, but due to strong historical links between the Welsh and certain English cities, there are churches using both the English and the Welsh languages in London, Manchester, Birmingham, Coventry and Liverpool.
