David Lloyd George, 1st Earl Lloyd-George of Dwyfor, (17 January 1863 – 26 March 1945) was Prime Minister of the United Kingdom from 1916 to 1922. A Liberal Party politician from Wales, he was known for leading the United Kingdom during the First World War, for social-reform policies (including the National Insurance Act 1911), for his role in the Paris Peace Conference, and for negotiating the establishment of the Irish Free State. He was the last Liberal Party prime minister; the party fell into third-party status shortly after the end of his premiership.
After becoming active in local politics, Lloyd George gained a reputation as an orator and a proponent of a Welsh blend of radical Liberal ideas, which included support for Welsh devolution, for the disestablishment of the Church of England in Wales, for equality for labourers and tenant farmers, and for reform of land ownership. In 1890 he narrowly won a by-election to become the Member of Parliament for Caernarvon Boroughs, in which seat he remained for 55 years. He served in Henry Campbell-Bannerman's cabinet from 1905. After H. H. Asquith succeeded to the premiership in 1908, Lloyd George replaced him as Chancellor of the Exchequer. To fund extensive welfare reforms he proposed taxes on land ownership and high incomes in the "People's Budget" (1909), which the Conservative-dominated House of Lords rejected. The resulting constitutional crisis was only resolved after two elections in 1910 and the passage of the 1911 Parliament Act. His budget was enacted in 1910, and the National Insurance Act 1911 and other measures helped to establish the modern welfare state. In 1913, he was embroiled in the Marconi scandal, but he remained in office and promoted the disestablishment of the Church of England in Wales until 1914, when its implementation was suspended in response to the outbreak of the First World War.
As wartime chancellor, Lloyd George strengthened the country's finances and forged agreements with trade unions to maintain production.
