1900 United Kingdom general election in the context of "Liberal Unionist Party"

Arthur James Balfour, 1st Earl of Balfour (/ˈbælfər, -fɔːr/; 25 July 1848 – 19 March 1930), was a British statesman and Conservative politician who served as Prime Minister of the United Kingdom from 1902 to 1905. As foreign secretary in the Lloyd George ministry, he issued the Balfour Declaration of 1917 on behalf of the cabinet, which supported a "home for the Jewish people" in Palestine, and later issued the Balfour Declaration of 1926 as Lord of the Privy Council, which announced a co-equal relationship between the United Kingdom and its Dominions, laying the groundwork for the Statute of Westminster 1931 which granted full independence to the former colonies.

Entering Parliament in 1874, Balfour achieved prominence as Chief Secretary for Ireland, in which position he suppressed agrarian unrest whilst taking measures against absentee landlords. He opposed Irish Home Rule, saying there could be no half-way house between Ireland remaining within the United Kingdom or becoming independent. From 1891 he led the Conservative Party in the House of Commons, serving under his uncle, Lord Salisbury, whose government won large majorities in 1895 and 1900. An esteemed debater, he was bored by the mundane tasks of party management.

The 1906 United Kingdom general election was held from 12 January to 8 February 1906. The Liberals under Henry Campbell-Bannerman won a landslide victory against a bewildered Conservative Party, in which its leader, Arthur Balfour, lost his seat; the party won the lowest number of seats it ever had in its history, a nadir unsurpassed until 2024. This particular landslide is now ranked alongside the 1924, 1931, 1945, 1983, 1997, 2001, and 2024 general elections as one of the largest landslide election victories.

The Labour Representation Committee was far more successful than at the 1900 general election and after the election would be renamed the Labour Party with 29 MPs and Keir Hardie as leader. The Irish Parliamentary Party, led by John Redmond, achieved its seats with a relatively low number of votes, as 73 candidates stood unopposed. This election was a landslide defeat for the Conservative Party and their Liberal Unionist allies, with the primary reason given by historians being the party's weakness after its split over the issue of free trade (Joseph Chamberlain had resigned from government in September 1903 in order to campaign for Tariff Reform, which would allow "preferential tariffs"). Many working-class people at the time saw this as a threat to the price of food, hence the debate was nicknamed "Big Loaf, Little Loaf". The Liberals' landslide victory of 125 seats over all other parties led to the passing of social legislation known as the Liberal reforms.

Sir Henry Campbell-Bannerman (né Campbell; 7 September 1836 – 22 April 1908) was a British statesman and Liberal Party politician who was Prime Minister of the United Kingdom from 1905 to 1908 and Leader of the Liberal Party from 1899 to 1908. He also was Secretary of State for War twice, in the cabinets of Gladstone and Rosebery. He was the first First Lord of the Treasury to be officially called the "Prime Minister", the term only coming into official usage five days after he took office. He remains the only person to date to hold the positions of Prime Minister and Father of the House at the same time, and the last Liberal leader to gain a UK parliamentary majority.

Known colloquially as "CB", Campbell-Bannerman firmly believed in free trade, Irish Home Rule and the improvement of social conditions, including reduced working hours. A. J. A. Morris, in the Oxford Dictionary of National Biography, called him "Britain's first and only Radical prime minister". Following a general-election defeat in 1900, Campbell-Bannerman went on to lead the Liberal Party to a landslide victory over the Conservative Party at the 1906 general election – the last election in which the Liberals gained an overall majority in the House of Commons. The government he subsequently led passed legislation to ensure trade unions could not be liable for damages incurred during strike action, introduced free school meals for all children, and empowered local authorities to purchase agricultural land from private landlords. Campbell-Bannerman resigned as prime minister in April 1908 due to ill-health and was replaced by his chancellor, H. H. Asquith. He died 19 days later – the only prime minister to die in the official residence, 10 Downing Street.

Andrew Bonar Law (/ˈbɒnər ˈlɔː/; 16 September 1858 – 30 October 1923) was a British statesman and politician who was Prime Minister of the United Kingdom from October 1922 to May 1923.

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, 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.
