George V's reign saw the rise of socialism, communism, fascism, Irish republicanism, and the Indian independence movement, all of which radically changed the political landscape. The Parliament Act 1911 established the supremacy of the elected British House of Commons over the unelected House of Lords. As a result of the First World War (1914–1918), the empires of his first cousins Tsar Nicholas II of Russia and Kaiser Wilhelm II of Germany fell, while the British Empire expanded to its greatest effective extent.

In 1917, George became the first monarch of the House of Windsor, which he renamed from the House of Saxe-Coburg and Gotha as a result of anti-German public sentiment. In 1924 he appointed the first Labour ministry and in 1931 the Statute of Westminster recognised the dominions of the Empire as separate, independent states within the Commonwealth of Nations.

Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was an American statesman and academic who served as the 28th president of the United States from 1913 to 1921.

A member of the Democratic Party, Wilson served as the president of Princeton University from 1902 to 1910, and as governor of New Jersey from 1911 to 1913, before winning the 1912 presidential election. As president, he oversaw the passage of progressive legislative policies unparalleled until the New Deal in 1933. He also led the United States during World War I, establishing an activist foreign policy known as "Wilsonianism." He was one of the three key leaders at the 1919 Paris Peace Conference, where he championed a new League of Nations, but he was unable to win Senate approval for US participation in the League.

David Lloyd George, 1st Earl Lloyd-George of Dwyfor, (17 January 1863 – 26 March 1945) was a British statesman and Liberal Party politician. He was the final Liberal to serve as Prime Minister of the United Kingdom.

As Chancellor of the Exchequer (1908–1915) during H. H. Asquith's tenure as Prime Minister, Lloyd George was a key figure in the introduction of many reforms which laid the foundations of the modern welfare state. His most important role came as the highly energetic Prime Minister of the Wartime Coalition Government (1916–22), during and immediately after the First World War. He was a major player at the Paris Peace Conference of 1919 that reordered Europe after the defeat of the Central Powers.

Arthur Meighen (16 June 1874 – 5 August 1960) was a Canadian lawyer and politician who served as the ninth prime minister of Canada, in office from July 1920 to December 1921 and again from June to September 1926. Meighen was born in rural Perth County, Ontario. Meighen entered the House of Commons of Canada in 1908, aged 34, and in 1913 was appointed to the Cabinet of Prime Minister Sir Robert Borden. In 1920, Meighen succeeded Borden as Conservative leader and Prime Minister. He suffered a heavy defeat in the 1921 election to Mackenzie King and the Liberal Party.

Meighen's brief second term as Prime Minister came about as the result of the "King–Byng Affair," being invited to form a ministry after Mackenzie King was refused an election request and resigned. He soon lost a no-confidence motion, however, and faced another federal election. Meighen lost his own seat, and the Conservatives lost 24, as Mackenzie King's Liberals re-took power.

Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th president of the United States from 1921 until his death in 1923, a member of the Republican Party.

At that time, he was one of the most popular U.S. presidents, but the subsequent exposure of scandals that took place under his administration such as Teapot Dome eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses. In historical rankings of the U.S. presidents, Harding is often rated among the worst.

Frederick Banting and Charles Best at the University of Toronto first isolated insulin. The first diabetes patient was treated on 11 January 1922. Banting and J.J.R. Macleod received the Nobel Prize for their achievement. [The award was controversial - see full article]

William Lyon Mackenzie King (December 17, 1874 – July 22, 1950) was the dominant Canadian political leader from the 1920s through the 1940s. He served as the tenth prime minister of Canada in 1921–1926, 1926–1930 and 1935–1948. He is best known for his leadership of Canada throughout the Second World War (1939–1945) when he mobilized Canadian money, supplies and volunteers to support Britain while boosting the economy and maintaining morale on the home front.

King acceded to the leadership of the Liberal Party in 1919. Taking the helm of a party bitterly torn apart during the First World War, he reconciled factions, unifying the Liberal Party and leading it to victory in the 1921 election. His party was out of office during the harshest days of the Great Depression in Canada, 1930–35; he returned when the economy was on an upswing.

A survey of scholars in 1997 by Maclean's magazine ranked King first among all Canada's prime ministers, ahead of Sir John A. Macdonald and Sir Wilfrid Laurier. As historian Jack Granatstein notes, "the scholars expressed little admiration for King the man but offered unbounded admiration for his political skills and attention to Canadian unity."
