William Ewart Gladstone in the context of "Equality of opportunity"

Gladstonian liberalism or Gladstonianism is a political doctrine named after the British Victorian Prime Minister and Liberal Party leader William Ewart Gladstone. Gladstonian liberalism consisted of limited government expenditure and low taxation whilst making sure government had balanced budgets and the classical liberal stress on self-help and freedom of choice. Gladstonian liberalism also emphasised free trade, opposed government intervention in the economy and supported freedom and liberty as moral ideals. It is referred to as laissez-faire or classical liberalism in the United Kingdom and is often compared to Thatcherism.

Gladstonian financial rectitude had a partial lasting impact on British politics and the historian John Vincent contends that under Lord Salisbury's premiership he "left Britain's low tax, low cost, low growth economy, with its Gladstonian finance and its free trade dogmas, and no conscript army, exactly as he had found it...Salisbury reigned, but Gladstone ruled". In the early 20th century the Liberal Party began to move away from Gladstonian liberalism and instead developed new policies based on social liberalism (or what Gladstone called "constructionism"). The Liberal government of 1905–1914 is noted for its social reforms and these included old age pensions and National Insurance. Taxation and public expenditure was also increased and New Liberal ideas led to David Lloyd George's People's Budget of 1909–1910.

The Liberal Party was one of the two major political parties in the United Kingdom, along with the Conservative Party, in the 19th and early 20th centuries. Beginning as an alliance of Whigs, free trade–supporting Peelites, and reformist Radicals in the 1850s, by the end of the 19th century, it had formed four governments under William Ewart Gladstone. Despite being divided over the issue of Irish Home Rule, the party returned to government in 1905 and won a landslide victory in the 1906 general election. Under prime ministers Henry Campbell-Bannerman (1905–1908) and H. H. Asquith (1908–1916), the Liberal Party passed reforms that created a basic welfare state. Although Asquith was the party leader, its dominant figure was David Lloyd George.

Asquith was overwhelmed by his wartime role as prime minister and Lloyd George led a coalition that replaced him in late 1916. However, Asquith remained as Liberal Party leader. The split between Lloyd George's breakaway faction and Asquith's official Liberal faction badly weakened the party. The coalition government of Lloyd George was increasingly dominated by the Conservative Party, which finally ousted him as prime minister in 1922. The subsequent Liberal collapse was quick and catastrophic. With 400 MPs elected in the 1906 election; they had only 40 in 1924. Their share of the popular vote plunged from 49% to 18%. The Labour Party absorbed most of the ex-Liberal voters and then became the Conservatives' main rival.

In the United Kingdom under the premiership of William Gladstone, the Representation of the People Act 1884 (48 & 49 Vict. c. 3), also known informally as the Third Reform Act, and the Redistribution Act of the following year were laws which further extended the suffrage in the UK after the Derby government's Reform Act 1867. Taken together, these measures extended the same voting qualifications as existed in the towns to the countryside, more than doubling the electorate in the counties, and essentially established the modern one member constituency as the normal pattern for parliamentary representation.

The bill was introduced by Gladstone on 28 February 1884. The Conservative-dominated House of Lords rejected the bill on 17 July but then passed it. It gained royal assent on 6 December of that year.

Benjamin Disraeli, 1st Earl of Beaconsfield (21 December 1804 – 19 April 1881), was a British statesman, Conservative politician and writer who twice served as Prime Minister of the United Kingdom. He played a central role in the creation of the modern Conservative Party, defining its policies and its broad outreach. Disraeli is remembered for his influential voice in world affairs, his political battles with the Liberal Party leader William Ewart Gladstone, and his one-nation conservatism or "Tory democracy". He made the Conservatives the party most identified with the British Empire and military action to expand it, both of which were popular among British voters. He is the only British prime minister to have been born Jewish.

Disraeli was born in Bloomsbury, at that time a part of Middlesex. His father left Judaism after a dispute at his synagogue; Benjamin became an Anglican at the age of 12. After several unsuccessful attempts, Disraeli entered the House of Commons in 1837. In 1846, Prime Minister Robert Peel split the party over his proposal to repeal the Corn Laws, which involved ending the tariff on imported grain. Disraeli clashed with Peel in the House of Commons, becoming a major figure in the party. When Lord Derby, the party leader, thrice formed governments in the 1850s and 1860s, Disraeli served as Chancellor of the Exchequer and Leader of the House of Commons.

Herbert Henry Asquith, 1st Earl of Oxford and Asquith (/ˈæskwɪθ/ ASS-kwith; 12 September 1852 – 15 February 1928), generally known as H. H. Asquith, was a British statesman and Liberal politician who was Prime Minister of the United Kingdom from 1908 to 1916. He was the last prime minister from the Liberal Party to command a majority government, and the most recent Liberal to have served as Leader of the Opposition. He played a major role in the design and passage of major liberal legislation and a reduction of the power of the House of Lords. In August 1914 Asquith took the United Kingdom of Great Britain and Ireland and the British Empire into the First World War. During 1915 his government was vigorously attacked for a shortage of munitions and the failure of the Gallipoli Campaign. He formed a coalition government with other parties, but failed to satisfy critics, was forced to resign in December 1916 and never regained power.

After attending Balliol College, Oxford, he became a successful barrister. In 1886 he was the Liberal candidate for East Fife, a seat he held for over thirty years. In 1892 he was appointed Home Secretary in William Ewart Gladstone's fourth ministry, remaining in the post until the Liberals lost the 1895 election. In the decade of opposition that followed, Asquith became a major figure in the party, and when the Liberals regained power under Sir Henry Campbell-Bannerman in 1905, Asquith was named Chancellor of the Exchequer. In 1908 Asquith succeeded him as prime minister. The Liberals were determined to advance their reform agenda. An impediment to this was the House of Lords, which rejected the People's Budget of 1909. Meanwhile, the South Africa Act 1909 passed. Asquith called an election for January 1910, and the Liberals won, though they were reduced to a minority government. After another general election in December 1910, he gained passage of the Parliament Act 1911, allowing a bill three times passed by the Commons in consecutive sessions to be enacted regardless of the Lords. Asquith was less successful in dealing with Irish Home Rule. Repeated crises led to gun running and violence, verging on civil war.

The Home Rule movement (Irish: Rialtas Dúchais) was a movement that campaigned for self-government (or "home rule") for Ireland within the United Kingdom of Great Britain and Ireland. It was the dominant political movement of Irish nationalism from 1870 to the end of World War I.

Isaac Butt founded the Home Government Association in 1870. This was succeeded in 1873 by the Home Rule League, and in 1882 by the Irish Parliamentary Party. These organisations campaigned for home rule. The House of Commons of the United Kingdom introduced the First Home Rule Bill in 1886, but the bill was defeated in the House of Commons after a split in the Liberal Party. After Parnell's death, Gladstone introduced the Second Home Rule Bill in 1893; it passed the Commons but was defeated in the House of Lords. After the removal of the Lords' veto in 1911, the Third Home Rule Bill was introduced in 1912, leading to the Home Rule Crisis. Shortly after the outbreak of World War I it was enacted, but implementation was suspended until the conclusion of the war.

Acton Smee Ayrton (5 August 1816 – 30 November 1886) was a British barrister and Liberal Party politician. Considered a radical and champion of the working classes, he served as First Commissioner of Works under William Ewart Gladstone between 1869 and 1873. He is best remembered for the "Ayrton controversy" over scientific facilities at Kew Gardens.

Robert Arthur Talbot Gascoyne-Cecil, 3rd Marquess of Salisbury (/ˈɡæskɔɪn ˈsɪsəl/ GASK-oyn SISS-əl; 3 February 1830 – 22 August 1903), known as Lord Salisbury, was a British statesman and Conservative politician who served as Prime Minister of the United Kingdom three times for a total of over thirteen years. He was also Foreign Secretary before and during most of his tenure. He avoided international alignments or alliances, maintaining the policy of "splendid isolation".

Lord Robert Cecil, later known as Lord Salisbury, was first elected to the House of Commons in 1854 and served as Secretary of State for India in Lord Derby's Conservative government 1866–1867. In 1874, under Disraeli, Salisbury returned as Secretary of State for India, and, in 1878, was appointed foreign secretary, and played a leading part in the Congress of Berlin. After Disraeli's death in 1881, Salisbury emerged as the Conservative leader in the House of Lords, with Sir Stafford Northcote leading the party in the Commons. He succeeded William Ewart Gladstone as prime minister in June 1885, and held the office until January 1886.

Portrait of William Ewart Gladstone is an 1879 portrait painting by the British artist John Everett Millais. It depicts the politician William Ewart Gladstone who served as Prime Minister four times. It was one of a series of portraits of leading figures Millais produced during the era, including his Portrait of Benjamin Disraeli featuring Gladstone's political rival. The work was initiated by Millais himself, rather than being commissioned and was then bought for a thousand pounds by the art dealer William Agnew who sold it ten days later to the Duke of Westminster.

The painting was displayed at the Royal Academy Exhibition of 1879 at Burlington House in London. Louisa Knightley described It as "undoubtedly the picture of the year" while Gladstone himself considered it a "a very fine work". It was A mezzotint was produced by the engraver Thomas Oldham Barlow, who submitted a version as his diploma work when elected to the Royal Academy of Arts in 1881. The original painting has been in the collection of the National Portrait Gallery since 1957, having previously been in the Tate Gallery.
