Andrew Bonar Law (known as Bonar; 16 September 1858 – 30 October 1923) was a British Conservative Party statesman and Prime Minister. Born in the colony of New Brunswick (now in Canada), he is the only British Prime Minister to have been born outside the British Isles. He was also the shortest-serving Prime Minister of the 20th century, spending 211 days in office. He had a much longer tenure as Conservative Party leader, November 1911 to March 1921 and October 1922 to May 1923, where he used his business background to good advantage in promoting better organisation and efficiency. His lack of aristocratic family connections helped him broaden the base of the party to include more businessmen.
