David Lloyd George, English-Welsh lawyer and politician, Prime Minister of the United Kingdom (born 1863)

David Lloyd George, 1st Earl Lloyd-George of Dwyfor 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, for his role in the Paris Peace Conference, and for negotiating the establishment of the Irish Free State.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.
