culture despite heavy English dominance. The publication of the extremely significant first complete Welsh translation of the Bible by William Morgan in 1588 greatly advanced the position of Welsh as a literary language. The 18th century saw the beginnings of two changes that would greatly affect Wales, the Welsh Methodist revival, which led the country to turn increasingly nonconformist in religion, and the Industrial Revolution. During the rise of the British Empire, 19th century Southeast Wales in particular experienced rapid industrialisation and a dramatic rise in population as a result of the explosion of the coal and iron industries. Wales played a full and willing role in World War One. The industries of the Empire in Wales declined in the 20th century with the end of the British Empire following the Second World War, while nationalist sentiment and interest in self-determination rose. The Labour Party replaced the Liberal Party as the dominant political force in the 1920s. Wales played a considerable role during World War Two along with the rest of the United Kingdom of Great Britain and Northern Ireland and the Allies, and its cities were bombed extensively during the Blitz. The nationalist party Plaid Cymru gained momentum from the 1960s. In a 1997 referendum, Welsh voters approved the devolution of governmental responsibility to a National Assembly for Wales which first met in 1999. In May 2020, the National Assembly for Wales was officially renamed Senedd Cymru or the Welsh Parliament (simply Senedd), to reflect significantly increased devolution and administrative power. Prehistoric era The earliest known human remains discovered in modern-day Wales is a Neanderthal jawbone, found at the Bontnewydd Palaeolithic site in the valley of the River Elwy in North Wales, whose owner lived about 230,000 years ago in the Lower Palaeolithic period. The Red Lady of Paviland, a human skeleton dyed in red ochre, was discovered in 1823 in one of the Paviland limestone caves of the Gower Peninsula in Swansea, South Wales. Despite the name, the skeleton is that of a young man who lived about 33,000 years ago at the end of the Upper Paleolithic Period (old Stone Age). It is considered to be the oldest known ceremonial burial in Western Europe. The skeleton was found along with jewellery made from ivory and seashells and a mammoth's skull. Following the last ice age, Wales became roughly the shape it is today by about 8000 BC
