Often ranked by historians as the single greatest prime minister in Canadian history, at first glance Mackenzie King can seem an unlikely choice for the honour. A mostly uncharismatic, unassuming man who today is known as much for his bizarre superstitious beliefs as anything else, King nevertheless served Canada competently as prime minister for over 20 years and six terms, and his tenure overlapped with many of the most pivotal moments of 20th century Canadian history.
A prominent Ontario lawyer, King was recruited to work as a bureaucrat in Ottawa’s newly-created Department of Labour, before running for Parliament in 1908 and becoming full-on minister of labour under Prime Minister Wilfrid Laurier (1841-1919). When Laurier died in 1919, King was elected to replace him as Liberal leader, a post he would hold for an amazing 29 years.
King was elected prime minister on three separate non-consecutive occasions. His first term (1921-1926) is remembered primarily for successful negotiations with London that secured Canada greater political independence within the Empire. Ironically, this first stint in power ended when he was briefly fired by Canada’s British-appointed governor general, Lord Byng (1862-1935) for complex political reasons (see: Arthur Meighen), though was easily re-elected back to office a few months later on a campaign of opposition to British “meddling” in Canadian affairs. Appearing cold and indifferent to the nation’s suffering during the Great Depression (1929-1939), King proceeded to loose his bid for a third term to R.B. Bennett (1870-1947) in 1930, and was out of power for a solid five years.
King’s third stint as PM overlapped with World War II (1939-1945). Though King had infamously described Adolph Hitler (1889-1945) as a man of peace during a 1937 meeting, once Britain declared war he became steadfast in opposition to the Nazi regime. A close friend of both President Franklin Roosevelt (1882-1945) and Britain’s Winston Churchill (1874-1965), King often served as an intermediary between the two men, and instigated the integration of Canada and the United States into a shared defense alliance. Over a million Canadians would fight overseas, but King famously avoided imposing a national draft until the war’s final days, aware of how unpopular the conflict was in Quebec.
After the war’s end, King presided over the beginnings of a post-war economic boom born from an increase in wartime manufacturing and spending. In 1948 he stepped down in favor of his attorney general, Louis St. Laurent (1882-1973), and died a year later.
