August 4th 2014 marks 100 years since the outbreak of World War One. Millions of soldiers from Wales and the rest of the UK enlisted to fight in the conflict, which lasted for four years between 1914 and 1918.
The declaration of war this day a century ago changed just about every life across Wales. It transformed David Lloyd George - from politician to statesman . He was - by 1918 - described as 'the man who won the war' - the Prime Minister and the most famous person in Britain. All this from a man who started life in a small cottage on the Lleyn peninsula: Rob Shelley has been looking at the life - and legacy - of Lloyd George.
People across Wales are switching off their lights for an hour this evening and lighting a candle of remembrance.
