David Lloyd George, 1st Earl Lloyd-George of Dwyfor OM, PC (17 January 1863 – 26 March 1945) was a British Liberal politician and statesman. He was Prime Minister of the United Kingdom at the head of a wartime coalition government between the years 1916–22 and was the Leader of the Liberal Party from 1926–31.
During a long tenure of office, mainly as Chancellor of the Exchequer, he was a key figure in the introduction of many reforms which laid the foundations of the modern welfare state. He was the last Liberal to be Prime Minister, as his coalition premiership was supported more by Conservatives than by his own Liberals, and the subsequent split was a key factor in the decline of the Liberal Party as a serious political force. When he eventually became leader of the Liberal Party a decade later he was unable to lead it back to power.
He is best known as the highly energetic Prime Minister (1916–22) who guided the Empire through the First World War to victory over Germany and her allies. He was a major player at the Paris Peace Conference of 1919 that reordered the world after the Great War. Lloyd George was a devout evangelical and an icon of 20th century liberalism as the founder of the welfare state. He is regarded as having made a greater impact on British public life than any other 20th century leader, thanks to his leadership of the war drive, his postwar role in reshaping Europe, and his introduction of Britain's social welfare system before the war.
Although many barristers have been Prime Minister, Lloyd George is to date the only solicitor to have held that office. He is also so far the only British Prime Minister to have been Welsh and to have spoken English as a second language, with Welsh being his first.
