Spencer Compton Cavendish, 8th Duke of Devonshire (23 July 1833 – 24 March 1908), styledLord Cavendish of Keighley between 1834 and 1858 andMarquess of Hartington between 1858 and 1891,^[1] was a British statesman. He has the distinction of having held leading positions in three political parties: leading theLiberal Party, theLiberal Unionist Party and theConservative Party in either theHouse of Commons or theHouse of Lords. After 1886 he increasingly voted with the Conservatives. He declined to become prime minister on three occasions, because the circumstances were never right. Historian and politicianRoy Jenkins said he was "too easy-going and too little of a party man." He held some passions, but he rarely displayed them regarding the most controversial issues of the day.^[2]

Devonshire was the eldest son ofWilliam Cavendish, 2nd Earl of Burlington, who succeededhis cousin as Duke of Devonshire in 1858, andLady Blanche Cavendish (née Howard).Lord Frederick Cavendish andLord Edward Cavendish were his younger brothers. He was educated atTrinity College, Cambridge, where he graduated asMA in 1854, having taken aSecond in theMathematical Tripos. He later was made honoraryLLD in 1862, and asDCL atOxford University in 1878.^[3]

In later life he continued his interests in education asChancellor of his old university from 1892, and ofManchester University from 1907 until his death. He wasLord Rector ofEdinburgh University from 1877 to 1880.^[3]

After joining the special mission toRussia forAlexander II's accession,^[4] Lord Cavendish of Keighley (as he was styled at the time) enteredParliament in the1857 general election, when he was returned forNorth Lancashire as a Liberal (his title "Lord Hartington", by which he became known in 1858, was acourtesy title; as he was not a peer in his own right he was eligible to sit in the Commons until he succeeded his father asDuke of Devonshire in 1891). Between 1863 and 1874, Lord Hartington held various Government posts, includingCivil Lord of the Admiralty andUnder-Secretary of State for War under Palmerston and Earl Russell. In the 1868 general election he lost his seat; having refused theLord Lieutenancy of Ireland, he was madePostmaster-General, without a seat in the Cabinet. The next year he re-entered the Commons, having been returned forRadnor. In 1870 Hartington reluctantly accepted the post ofChief Secretary for Ireland inGladstone's first government.

In 1875 – the year following Liberal defeat ata general election — he succeededWilliam Ewart Gladstone as Leader of the Liberal opposition in the House of Commons, after the other serious contender,W. E. Forster, had indicated that he was not interested in the post. The following year, however, Gladstone returned to active political life in the campaign against Turkey'sBulgarian Atrocities. The relative political fortunes of Gladstone and Hartington fluctuated – Gladstone was not popular at the time ofBenjamin Disraeli's triumph at the Congress of Berlin, but the Midlothian Campaigns of 1879–80 marked him out as the Liberals' foremost public campaigner.

In 1880, after Disraeli's government lost the general election, Hartington was invited by the Queen to form a government, but declined – as didthe Earl Granville, Liberal Leader in the House of Lords – after Gladstone made it clear that he would not serve under anybody else. Hartington chose instead to serve in Gladstone's second government asSecretary of State for India (1880–1882) andSecretary of State for War (1882–1885).

In 1884 he was instrumental in persuading Gladstone to sendGeneral Gordon on a mission to evacuate the Sudan. Despite the repeated objections of consul-general in EgyptSir Evelyn Baring, the indomitable Gordon was finally sent to Khartoum, where he did exactly the opposite of what he was sent to do, resulting in the siege of the city by the Mahdi and the final massacre of Gordon and 20,000 Arabs. Before the imminent catastrophe, Hartington persuaded Gladstone to send troops for the relief of Khartoum which arrived two days too late.^[5] A considerable number of the Conservative party long held him chiefly responsible for the "betrayal of Gordon". His lethargic manner, apart from his position as war minister, helped to associate him in their minds with a disaster which emphasized the fact that the government acted "too late"; but Gladstone and Lord Granville were no less responsible than he.^[6]

Hartington became increasingly uneasy with Gladstone's Irish policies, especially after themurder of his younger brother Lord Frederick Cavendish in Phoenix Park. After being elected in December 1885 for the newly createdRossendale Division of Lancashire, he broke with Gladstone altogether. He declined to serve in Gladstone'sthird government, formed after Gladstone came out in favour ofIrish Home Rule (unlike Joseph Chamberlain, who accepted the Local Government Board but then resigned), and after opposing theFirst Home Rule Bill became the leader of the Liberal Unionists. After thegeneral election of 1886 Hartington declined to become Prime Minister, preferring instead to hold the balance of power in the House of Commons and give support from the back benches to the second Conservative government of Lord Salisbury. Early in 1887, after the resignation ofLord Randolph Churchill, Salisbury offered to step down and serve in a government under Hartington, who now declined the premiership for the third time. Instead the Liberal UnionistGeorge Goschen accepted the Exchequer in Churchill's place.

Having succeeded asDuke of Devonshire in 1891 he entered the House of Lords where, in 1893, he formally moved for the rejection of theSecond Home Rule Bill. Devonshire eventually joined Salisbury's third government in 1895 asLord President of the Council, and from March 1900 was alsoPresident of the Board of Education.^[7] Devonshire was not asked to become Prime Minister whenLord Salisbury retired in favour of his nephewArthur Balfour in 1902. He resigned from the government in 1903, and from the Liberal Unionist Association the following spring, in protest atJoseph Chamberlain'sTariff Reform scheme. Devonshire said of Chamberlain's proposals:

I venture to express the opinion that [Chamberlain] will find among the projects and plans which he will be called upon to discuss none containing a more Socialistic principle than that which is embodied in his own scheme, which, whether it can properly be described as a scheme of protection or not, is certainly a scheme under which the State is to undertake to regulate the course of commerce and of industry, and tell us where we are to buy, where we are to sell, what commodities we are to manufacture at home, and what we may continue, if we think right, to import from other countries.^[8]

Balfour, trying to juggle different factions, had allowed both Chamberlain and Free Trade supporters to resign from the government, hoping that Devonshire would remain for the sake of balance, but the latter eventually resigned under pressure fromCharles Thomson Ritchie and from his wife, who still hoped that he might lead a government including leading Liberals. But in the autumn of 1907 his health gave way, and grave symptoms of cardiac weakness necessitated his abstaining from public effort and spending the winter abroad. He died, rather suddenly of pneumonia in his home after falling ill on his vacation to Cannes, on 24 March 1908.^[6]

He served part-time as captain in theDuke of Lancaster's Own Yeomanry from 1855 to 1873, and was honorary colonel of the 3rd (Militia) Battalion of theDerbyshire Regiment from 1871 and of the2nd Sussex Artillery Volunteers from 1887.^[9]

Hartington took great pains to parade his interest in horseracing, so as to cultivate an image of not being entirely obsessed by politics. For many years, the courtesanCatherine Walters ("Skittles") was his mistress. He was married at Christ Church,Mayfair, on 16 August 1892, at the age of 59, toLouisa Frederica Augusta von Alten, widow of the lateWilliam Drogo Montagu, 7th Duke of Manchester.

Upon his death, he was succeeded by his nephewVictor Cavendish. He died ofpneumonia at theChatsworth House inDerbyshire and was interred on 28 March 1908 atSt Peter's Churchyard, Edensor,Derbyshire. A statue of the Duke can be found at the junction ofWhitehall andHorse Guards Avenue inLondon, and also on the Western Lawns at Eastbourne.

Upon receiving news of the Duke's death, the House of Lords took the unprecedented step of adjourning in his honour.^[10]Margot Asquith said the Duke of Devonshire "was a man whose like we shall never see again; he stood by himself and could have come from no country in the world but England. He had the figure and appearance of an artisan, with the brevity of a peasant, the courtesy of a king and the noisy sense of humour of aFalstaff. He gave a great, wheezy guffaw at all the right things and was possessed of endless wisdom. He was perfectly disengaged from himself, fearlessly truthful and without pettiness of any kind".^[11]

HistorianJonathan Parry claimed that "He inherited the whig belief in the duty of political leadership, afforced by the intellectual notions characteristic of well-educated, propertied early to mid-Victorian Liberals: a confidence that the application of free trade, rational public administration, scientific enquiry, and a patriotic defence policy would promote Britain's international greatness—in which he strongly believed—and her economic and social progress...he became a model of the dutiful aristocrat".^[12] It has been said^{[according to whom?]} that he was "the best excuse that the last half-century has produced for the continuance of the peerages".

With 24 years of government service, Devonshire's is the fourth longest ministerial career in modern British politics.^[13]
