The sickly heir to the Peelite George Hamilton Gordon, 4th earl of Aberdeen, Haddo suppressed his Conservative tendencies while his father was alive. He was ‘a Liberal-Conservative in politics, but was by no means a party man; and, indeed the weak state of his health prevented him in a great measure from the active discharge of his parliamentary duties’.
After a grand tour of Europe, Haddo served as attaché to the British embassy at Constantinople in 1837, an appointment probably secured through his father’s influence. His father was foreign secretary in Sir Robert Peel’s second administration, 1841-6, but Haddo showed little political ambition at this time. A cultured man, Haddo was a talented amateur painter and had an anonymously submitted landscape displayed at the 1843 Royal Academy exhibition.
Lord Aberdeen became prime minister of a Whig-Peelite coalition in December 1852 and the appointment of his Derbyite brother William Gordon to naval command in August 1854 created a vacancy for Aberdeenshire. Lord Aberdeen wrote that his chronically ill heir ‘seems to have no objections to come into Parliament’.
Haddo’s health improved slightly as a result of his Egyptian sojourn, but he was still overseas when his father’s government was turned out on Roebuck’s motion for an inquiry into the state of the army at Sebastopol, 29 Jan. 1855. He played no part in the debates on the mismanagement of the Crimean war in the same session. Accordingly it was left to his younger brother Arthur to defend their father in the Commons, 17 July 1855.
Haddo missed most of the crucial party votes in the later 1850s due to his poor health, although he sided with disgruntled Peelites, Liberals and Conservatives in defeating Palmerston’s government over Canton, 3 Mar. 1857. Much to his father’s annoyance, Haddo behaved ‘very foolishly’ at the consequent general election by delaying his return to Aberdeenshire until the latest possible moment.
Thereafter Haddo increasingly focused his attention on two issues. Firstly, with William Henry Sykes, Liberal MP for Aberdeen, he led the parliamentary opposition to the proposed amalgamation of Aberdeen’s universities, King’s and Marischal Colleges. He voiced the broad and deep hostility to the measure from Aberdeenshire and argued that no ‘public advantage’ would be gained from the union of two colleges that had thrived as independent institutions, 25 June 1858.
Secondly, Haddo attempted to prevent public money going to art schools that employed nude female models in 1858, 1859 and 1860. The modest artistic benefits of nude study, Haddo argued, had to be weighed against ‘many evils’, such as debasing the ‘humbler classes’.
Haddo was in Egypt when he succeeded his father as 5th earl of Aberdeen in December 1860.
Thereafter Lord Aberdeen generally resided at his seat Haddo House, although in May 1863 he travelled to Madrid to petition the queen of Spain for the remission of a man, Manuel Matamoros, who had been sentenced to nine years penal servitude for preaching Protestantism.
