Andrew Bonar Law (; 16 September 1858 – 30 October 1923) was a British Conservative politician who was Prime Minister of the United Kingdom from 1922 to 1923. He was the first prime minister born outside of Britain and the shortest-serving British prime minister of the 20th century.
Law was born in the British colony of New Brunswick (now a Canadian province). He was of Scottish and Ulster Scots descent and moved to Scotland in 1870. He left school aged sixteen to work in the iron industry, becoming a wealthy man by the age of thirty. He entered the House of Commons at the 1900 general election at age 42, relatively late in life for a front-rank politician; he was made a junior minister, Parliamentary Secretary to the Board of Trade, in 1902. Law joined the Shadow Cabinet in opposition after the 1906 general election. In 1911, he was appointed a Privy Councillor, before standing for the vacant party leadership. Despite never having served in the Cabinet and trailing third after Walter Long and Austen Chamberlain, Law became leader when the two front-runners withdrew rather than risk a draw splitting the party.
As Leader of the Conservative Party and Leader of the Opposition, Law focused his attentions in favour of tariff reform and against Irish Home Rule. His campaigning helped turn Liberal attempts to pass the Third Home Rule Bill into a three-year struggle eventually halted by the start of World War I, with much argument over the status of the six counties in Ulster which would later become Northern Ireland, four of which were predominantly Protestant.
Law first held Cabinet office as Secretary of State for the Colonies in H. H. Asquith's Coalition Government (May 1915 – December 1916). Upon Asquith's fall from power he declined to form a government, instead becoming Chancellor of the Exchequer in David Lloyd George's Coalition Government. He resigned on grounds of ill health early in 1921. In October 1922, with Lloyd George's Coalition having become unpopular with the Conservatives, he wrote a letter to the press giving only lukewarm support to the Government's actions over Chanak. After Conservative MPs voted to end the Coalition, he again became party leader and, this time, prime minister. Bonar Law won a clear majority at the 1922 general election, and his brief premiership saw negotiation with the United States over Britain's war loans. Seriously ill with throat cancer, Law resigned in May 1923, and died later that year. He was the fourth shortest-serving prime minister of the United Kingdom (211 days in office).
Andrew Bonar Law was born on 16 September 1858 in Kingston (now Five Rivers), New Brunswick, to the Reverend James Law, a minister of the Free Church of Scotland, and his wife Eliza Kidston Law. He was of Scottish and Irish (mainly Ulster Scots) ancestry. At the time of his birth, New Brunswick was still a separate colony, as the Canadian Confederation was not formed until 1867.
His mother originally wanted to name him after Robert Murray McCheyne, a preacher she greatly admired, but as his older brother was already called Robert, he was instead named after Andrew Bonar, a biographer of McCheyne. Throughout his life he was always called Bonar by his family and close friends, never Andrew. He originally signed his name as A. B. Law, changing to A. Bonar Law in his thirties. He was referred to as Bonar Law by the public.
James Law was the minister for several isolated townships, and had to travel between them by horse, boat and on foot. To supplement the family income, he bought a small farm on the Richibucto River, which Bonar helped tend along with his brothers Robert, William and John, and his sister Mary. Studying at the local village school, Law did well at his studies, and it is here that he was first noted for his excellent memory. After Eliza Law died in 1861, her sister Janet travelled to New Brunswick from her home in Scotland to look after the Law children. When James Law remarried in 1870, his new wife took over Janet's duties, and Janet decided to return home to Scotland. She suggested that Bonar Law should go with her, as the Kidston family were wealthier and better connected than the Laws, and Bonar would have a more privileged upbringing. Both James and Bonar accepted this, Bonar's father then accompanied him on his move to his aunt's. Bonar would never return to Kingston.
Law went to live at Janet's house in Helensburgh, near Glasgow. Her brothers Charles, Richard and William were partners in the family merchant bank Kidston & Sons, and as only one of them had married (and produced no heir) it was generally accepted that Law would inherit the firm, or at least play a role in its management when he was older. Immediately upon arriving from Kingston, Law began attending Gilbertfield House School, a preparatory school in Hamilton. In 1873, aged fourteen, he transferred to the High School of Glasgow, where with his good memory he showed a talent for languages, excelling in Greek, German and French. During this period, he first began to play chess – he would carry a board on the train between Helensburgh and Glasgow, challenging other commuters to matches. He eventually became a very good amateur player, and competed with internationally renowned chess masters. Despite his good academic record, it became obvious at Glasgow that he was better suited to business than to university, and when he was sixteen, Law left school to become a clerk at Kidston & Sons.
At Kidston & Sons, Law received a nominal salary, on the understanding that he would gain a "commercial education" from working there that would serve him well as a businessman. In 1885 the Kidston brothers decided to retire, and agreed to merge the firm with the Clydesdale Bank.
The merger would have left Law without a job and with poor career-prospects, but the retiring brothers found him a job with William Jacks, an iron merchant who had started pursuing a parliamentary career. The Kidston brothers lent Law the money to buy a partnership in Jacks' firm, and with Jacks himself no longer playing an active part in the company, Law effectively became the managing partner. Working long hours (and insisting that his employees did likewise), Law turned the firm into one of the most profitable iron merchants in the Glaswegian and Scottish markets.
During this period Law became a "self-improver"; despite his lack of formal university education, Law sought to test his intellect, attending lectures given at Glasgow University and joining the Glasgow Parliamentary Debating Association, which adhered as closely as possible to the layout of the real Parliament of the United Kingdom. This helped Law hone the skills that served him so well in the political arena.
By the time he was thirty, Law had established himself as a successful businessman. He had time to devote to more leisurely pursuits. He remained an avid chess player, whom Andrew Harley called "a strong player, touching first-class amateur level, which he had attained by practice at the Glasgow Club in earlier days". Law also worked with the Parliamentary Debating Association, and took up golf, tennis and walking. In 1888 he moved out of the Kidston household and set up his own home at Seabank, with his sister Mary (who had earlier come over from Canada) acting as the housekeeper.
In 1890, Law met Annie Pitcairn Robley, the 24-year-old daughter of a Glaswegian merchant, Harrington Robley. They quickly fell in love, and married on 24 March 1891. Little is known of Law's wife, as most of her letters have been lost. It is known that she was much liked in both Glasgow and London, and that her death in 1909 hit Law hard; despite his relatively young age and prosperous career, he never remarried. The couple had six children: James Kidston (1893–1917), Isabel Harrington (1895–1969), Charles John (1897–1917), Harrington (1899–1958), Richard Kidston (1901–1980), and Catherine Edith (1905–1992).
Law's second son, Charlie, a lieutenant in the King's Own Scottish Borderers, was killed at the Second Battle of Gaza in April 1917. His eldest son, James, a captain in the Royal Fusiliers, was shot down and killed on 21 September 1917. The deaths made Law even more melancholy and depressed than before. The youngest son, Richard, later served as a Conservative MP and minister. Isabel married Sir Frederick Sykes (in the early years of World War I, she had been engaged for a time to the Australian war correspondent Keith Murdoch) and Catherine married, firstly, Kent Colwell and, much later, in 1961, The 1st Baron Archibald.
