Katharine Marjory Stewart-Murray, Duchess of Atholl, DBE (née Ramsay; 6 November 1874 – 21 October 1960), known as the Marchioness of Tullibardine from 1899 to 1917, was a British noblewoman and Scottish Unionist Party politician whose views were often unpopular in her party.
James Ramsay MacDonald (né James McDonald Ramsay; 12 October 1866 – 9 November 1937) was a British statesman and politician who served as Prime Minister of the United Kingdom, the first who belonged to the Labour Party, leading minority Labour governments for nine months in 1924 and again between 1929 and 1931. From 1931 to 1935, he headed a National Government dominated by the Conservative Party and supported by only a few Labour members. MacDonald was expelled from the Labour Party as a result.
MacDonald, along with Keir Hardie and Arthur Henderson, was one of the three principal founders of the Labour Party in 1900. He was chairman of the Labour MPs before 1914 and, after an eclipse in his career caused by his opposition to the First World War, he was Leader of the Labour Party from 1922. The second Labour Government (1929–1931) was dominated by the Great Depression. He formed the National Government to carry out spending cuts to defend the gold standard, but it had to be abandoned after the Invergordon Mutiny, and he called a general election in 1931 seeking a "doctor's mandate" to fix the economy.
The National coalition won an overwhelming landslide and the Labour Party was reduced to a rump of around 50 seats in the House of Commons. His health deteriorated and he stood down as Prime Minister in 1935, remaining as Lord President of the Council until retiring in 1937. He died later that year.
MacDonald's speeches, pamphlets and books made him an important theoretician. Historian John Shepherd states that "MacDonald's natural gifts of an imposing presence, handsome features and a persuasive oratory delivered with an arresting Highlands accent made him the iconic Labour leader". After 1931, MacDonald was repeatedly and bitterly denounced by the Labour movement as a traitor to its cause. Since the 1960s, some historians have defended his reputation, emphasising his earlier role in building up the Labour Party, dealing with the Great Depression, and as a forerunner of the political realignments of the 1990s and 2000s.
Joseph Sullivan (8 September 1866 – 13 February 1935) was a Scottish Labour Party politician who served as a Member of Parliament (MP) from 1922 to 1924, and from 1926 to 1931.
John William Muir (15 December 1879 – 11 January 1931) was the editor of The Worker, a newspaper of the Clyde Workers' Committee, who was prosecuted under the Defence of the Realm Act for an article criticising World War I.
Born in Glasgow, by the early 1910s, Muir was the editor of The Socialist, the newspaper of the Socialist Labour Party. However, he resigned the post in 1914, as he was in favour of the war.
He became involved in the Shop Stewards' Movement and was a member of the Clyde Workers' Committee, an organisation that had been formed to campaign against the Munitions Act, which forbade engineers from leaving the works where they were employed. For publishing an article in The Worker entitled "Should the workers arm?", Muir was jailed for twelve months, alongside Willie Gallacher.
In 1917, Muir joined the Independent Labour Party and became close to John Wheatley. In the 1918 election, he stood for the Labour Party in Glasgow Maryhill but was unsuccessful. He won the seat in the 1922 general election and retained the seat in 1923. He lost his seat in the 1924 election after which he ran the Workers Educational Association until 1930.
