George Hamilton-Gordon, 4th Earl of Aberdeen (28 January 178414 December 1860), styled Lord Haddo from 1791 to 1801, was a British statesman, diplomat and landowner, successively a Tory, Conservative and Peelite politician and specialist in foreign affairs. He served as Prime Minister from 1852 until 1855 in a coalition between the Whigs and Peelites, with Radical and Irish support. The Aberdeen ministry was filled with powerful and talented politicians, whom Aberdeen was largely unable to control and direct. Despite his efforts to avoid this happening, his ministry took Britain into the Crimean War, and fell when the war's conduct became unpopular. Subsequently, Aberdeen retired from politics.

Born into a wealthy family with the largest estates in Scotland, his personal life was marked by the loss of both parents by the time he was eleven, and of his first wife after only seven years of a happy marriage. His daughters died young, and his relations with his sons were difficult.MacIntyre, 644 He travelled extensively in Europe, including Greece, and he had a serious interest in the classical civilisations and their archaeology. Aberdeen inherited and subsequently modernized his father's Scottish estates.

After 1812 he became a diplomat, and in 1813, at age 29, was given the critically important embassy to Vienna, where he organised and financed the sixth coalition that defeated Napoleon. His rise in politics was equally rapid and lucky, and "two accidents — Canning's death and Wellington's impulsive acceptance of the Canningite resignations" led to his becoming Foreign Secretary for Prime Minister Wellington in 1828 despite "an almost ludicrous lack of official experience"; he had been a minister for less than six months. After holding the position for two years, followed by another cabinet role, by 1841 his experience led to his appointment as Foreign Secretary again under Robert Peel for a longer term.MacIntyre, 641 His diplomatic successes include organizing the coalition against Napoleon in 1812–1814, normalizing relations with post-Napoleonic France, settling the old border dispute between Canada and the United States, and ending the First Opium War with China in 1842, whereby Hong Kong was obtained. Aberdeen was a poor speaker, but this scarcely mattered in the House of Lords. He exhibited a "dour, awkward, occasionally sarcastic exterior".MacIntyre, 642, 644. His friend William Ewart Gladstone, said of him that he was "the man in public life of all others whom I have loved. I say emphatically loved. I have loved others, but never like him".MacIntyre, 643, quoted

Early life Born in Edinburgh on 28 January 1784, he was the eldest son of George Gordon, Lord Haddo, son of George Gordon, 3rd Earl of Aberdeen. His mother was Charlotte, youngest daughter of William Baird of Newbyth. He lost his father on 18 October 1791 and his mother in 1795, and he was brought up by Henry Dundas, 1st Viscount Melville, and William Pitt the Younger. He was educated at Harrow, and St John's College, Cambridge, where he graduated with a Master of Arts in 1804. Before this, however, he had become Earl of Aberdeen on his grandfather's death in 1801, and had travelled all over Europe. On his return to Britain, he founded the Society of Athenian Travellers. In 1805, he married Lady Catherine Elizabeth, daughter of John Hamilton, 1st Marquess of Abercorn.

Political and diplomatic career, 1805–1828 In December 1805, Lord Aberdeen took his seat as a Tory Scottish representative peer in the House of Lords. In 1808, he was created a Knight of the Thistle. Following the death of his wife from tuberculosis in 1812 he joined the Foreign Service. He was appointed Ambassador Extraordinary and Minister Plenipotentiary to Austria, and signed the Treaty of Töplitz between Britain and Austria in Vienna in October 1813. In the company of the Austrian Emperor, Francis II, he was an observer at the decisive Coalition victory of the Battle of Leipzig in October 1813; he had met Napoleon in his earlier travels. He became one of the central diplomatic figures in European diplomacy at this time, and he was one of the British representatives at the Congress of Châtillon in February 1814, and at the negotiations which led to the Treaty of Paris in May of that year.Chambers Biographical Dictionary, , page 4

Aberdeen was greatly affected by the aftermath of war which he witnessed at first hand. He wrote home:The near approach of war and its effects are horrible beyond what you can conceive. The whole road from Prague to [Teplitz] was covered with waggons full of wounded, dead, and dying. The shock and disgust and pity produced by such scenes are beyond what I could have supposed possible...the scenes of distress and misery have sunk deeper in my mind. I have been quite haunted by them.

Returning home he was created a peer of the United Kingdom as Viscount Gordon, of Aberdeen in the County of Aberdeen (1814), and made a member of the Privy Council.

In July 1815, he married his former sister-in-law Harriet, daughter of John Douglas, and widow of James Hamilton, Viscount Hamilton; the marriage was much less happy than his first. During the ensuing thirteen years Aberdeen took a less prominent part in public affairs.

Political career, 1828–1852

Lord Aberdeen served as Chancellor of the Duchy of Lancaster between January and June 1828 and subsequently as Foreign Secretary until 1830 under the Duke of Wellington. He resigned with Wellington over the Reform Bill of 1832.

He was Secretary of State for War and the Colonies in the first Peel ministry (December 1834 - April 1835), and again Foreign Secretary between 1841 and 1846 under Sir Robert Peel (second Peel ministry). It was during his second stint as Foreign Secretary that he had the harbor settlement of 'Little Hong Kong', on the south side of Hong Kong Island, named after him. It was probably the most productive period of his career; he settled two disagreements with the US: the northeast boundary dispute by the Webster-Ashburton Treaty (1842), and the Oregon dispute by the Oregon Treaty of 1846. He enjoyed the trust of Queen Victoria, which was still important for a Foreign Secretary. He worked closely with Henry Bulwer, his ambassador to Madrid, to help arrange marriages for Queen Isabella and her younger sister the Infanta Luisa Fernanda. They helped stabilize Spain's internal and external relations.Laurence Guymer, "The Wedding Planners: Lord Aberdeen, Henry Bulwer, and the Spanish Marriages, 1841–1846." Diplomacy & Statecraft 21.4 (2010): 549–573. He sought better relations with France, relying on his friendship with Guizot, but Britain was aggrieved by a series of issues, especially French colonial policies, the right to search slave ships, the French desire to control Belgium, disputes in the Pacific and the French intervention in Morocco.A.B. Cunningham, "Peel, Aberdeen and the Entente cordiale." Historical Research 30.82 (1957): 189–206.Robert Seton-Watson, Britain in Europe: 1789-1914 (1937) pp 223–41. (online)

In opposition Aberdeen again followed his leader and resigned with Peel over the issue of the Corn Laws. After Peel's death in July 1850 he became the recognised leader of the Peelites. In August 1847, a general election of Parliament had been held which resulted in the election of 325 Tory/Conservative party members to Parliament. This represented 42.7% of the seats in Parliament. The main opposition to the Tory/Conservative Party was the Whig Party, which had 292 seats.Lucille Iremonger, Lord Aberdeen: a biography of the fourth Earl of Aberdeen, KG, KT, Prime Minister 1852–1855 (1978).

While the Peelites agreed with the Whigs on issues dealing with international trade, there were other issues on which the Peelites disagreed with the Whigs. Indeed, Lord Aberdeen's own dislike of the Ecclesiastical Titles Assumption Bill, the rejection of which he failed to secure in 1851, prevented him from joining the Whig government of Lord John Russell in that year. Additionally, 113 of the members of Parliament elected in 1847 were Free Traders.Karl Marx, "Result of the Elections" contained in the Collected Works of Karl Marx and Frederick Engels: Volume 11, p. 352. These members agreed with the Peelites on the repeal of the "Corn Laws", but they felt that the tariffs on all consumer products should be removed.

Furthermore, 36 members of Parliament elected in 1847 were members of the "Irish Brigade", who voted with the Peelites and the Whigs for the repeal of the Corn Laws because they sought an end the Great Irish Famine by means of cheaper wheat and bread prices for the poor and middle classes in Ireland. Currently, however, the Free Traders and the Irish Brigade had disagreements with the Whigs that prevented them from joining with the Whigs to form a government. Accordingly, the Tory/Conservative Party leader the Earl of Derby was asked to form a "minority government". Derby appointed Benjamin Disraeli as the Chancellor of the Exchequer for the minority government. The general election in July 1852 had no clear winner.

When in December 1852 Disraeli submitted his budget to Parliament on behalf of the minority government, the Peelites, the Free Traders, and the Irish Brigade were all alienated by the proposed budget. Accordingly, those groups suddenly forgot their differences with the Whig Party and voted with the Whigs against the proposed budget. The vote was 286 in favour of the budget and 305 votes against the budget.Karl Marx, "The Defeat of the Ministry" contained in the Collected Works of Karl Marx and Frederick Engels: volume 11, p. 466. Because the leadership of the minority government had made the vote on the budget vote a vote of confidence, the defeat of the Disraeli budget was a "vote of no confidence" in the minority government and meant its downfall. Lord Aberdeen was asked to form a new government; Gladstone became his Chancellor.

Prime Minister, 1852–1855

Following the downfall of the Tory/Conservative minority government under Lord Derby in December 1852, Lord Aberdeen formed a new government from the coalition of Free Traders, Peelites, and Whigs that had voted no confidence in the minority government. Lord Aberdeen was able to put together a coalition that held 53.8% of the seats of Parliament. Thus Lord Aberdeen, a Peelite, became Prime Minister and headed a coalition ministry of Whigs and Peelites.

Although united on international trade issues and on questions of domestic reform, his cabinet also contained Lord Palmerston and Lord John Russell, who were certain to differ on questions of foreign policy. Charles Greville wrote in his Memoirs, "In the present cabinet are five or six first-rate men of equal, or nearly equal, pretensions, none of them likely to acknowledge the superiority or defer to the opinions of any other, and every one of these five or six considering himself abler and more important than their premier"; and Sir James Graham wrote, "It is a powerful team, but it will require good driving", which Aberdeen was unable to provide. During the administration, much trouble was caused by the rivalry between Palmerston and Russell, and over the course of it Palmerston managed to out-manoeuvre Russell to emerge as the Whig heir apparent.Martin, 110–112 The cabinet also included a single Radical, Sir William Molesworth, but much later, when justifying to the Queen his own new appointments, Gladstone told her: "For instance, even in Ld Aberdeen's Govt, in 52, Sir William Molesworth had been selected, at that time, a very advanced Radical, but who was perfectly harmless, & took little, or no part.... He said these people generally became very moderate, when they were in office", which she admitted had been the case.Queen Victoria's Journals, Wednesday 28 April 1880, Windsor Castle, from Princess Beatrice's copies, Volume72 (1 January 1880 – 18 August 1880), p.167, online from the Bodleian Library
