The lists below are comprised of British Prime Ministers. The Prime Minister is appointed by the British monarch, the nominal head of state, and governs in the monarch's name. In modern times the Prime Minister is regarded as the real leader of the country.
The position evolved slowly and was never created by any law. Robert Walpole (1676-1745) is generally viewed as the first Prime Minister after he became the First Lord of the Treasury in 1721.
