Scope and Content

This series of letters and papers was created or kept by William Cavendish, Marquess of Hartington in the period before he became the 4th Duke of Devonshire (after the death of his father) on 5th December 1755.
The letters cover significant times including going abroad to finish his education on the grand tour, his engagement and marriage to Lady Charlotte Boyle, sitting in the House of Commons as an MP and his role as Master of the Horse and Lord Lieutenant of Ireland up to the day he succeeded his father as Duke and took up his seat in the House of Lords.

The letters to Dr R. Newcome from 1739 - 1740 concern Lord Hartington's grand tour across Europe and include descriptions of what he saw; how he travelled; where he stayed; who he met; the reception he received; the customs and ceremonies including assemblies. He includes mention of entertainment including dancing, fencing, music, learning languages, studying architecture and playing card games such as Quadrille and Pharo.

From 1741 Lord Hartington writes to Dr Newcome concerning general personal news as well as politics in Parliament and current affairs. He considers Dr Newcome's question of the likelihood of war with Spain and France and; he reports the planned proroguing of Parliament. He mentions his travel plans and people he has seen including Dr Cheyney, as well as conversations with his father, advice for Dr Newcome and his compliments to people with Dr Newcome and his intentions to visit.

In1744-1745 he writes to Dr Newcome of: his proposed marriage to Lady Charlotte Boyle when she is of age (CS1/260/44); the bill to make correspondence with the Pretender's son a treasonous offence; sitting for his picture by Mr Davison (CS1/260/47); an account of the Jacobite rebels and General Wade's actions (starting from CS1/260/57).

To Wellbore Ellis he writes concerning the death of his friend James who he was living with and his dislike for Bath (CS1/260/8).

A draft letter to Richard Boyle, 3rd Earl of Burlington concerns his gratitude for having Lord Burlington's permission to marry Lady Charlotte and his honourable intentions (CS1/260/53).

To his father, the 3rd Duke of Devonshire, Lord Hartington writes, over a 13-year period, concerning his personal as well as foreign affairs taking place as well as events occurring such as births, deaths and marriages of people known to him and the 3rd Duke. There is also some mention of estate matters that concern the Cavendish family. However, most of these letters cover political affairs relating to Lord Hartington's roles as an MP (1741-1751) sitting in the House of Commons, Master of the Horse and a Privy Councillor (1751-1755). and then as Lord Lieutenant of Ireland (1755-1757). There is a clear change in the type of political affairs he reports to his father as His role changes from one in the House of Commons to one in the head of state's court and then to the head of the government of Ireland. After his marriage to Lady Charlotte in 1748, his letters to his father also contain more personal news.

In these letters to the 3rd Duke, Lord Hartington includes details of:

Administrative / Biographical History

Born in 1720, William Cavendish was the eldest son of William Cavendish, 3rd Duke of Devonshire, and his wife Catherine (née Hoskyns). From 1729, when his father succeeded to the dukedom, he held the title Marquess of Hartington. He was probably educated at home before undertaking the grand tour to France and Italy in 1739-40, accompanied by his tutor, the Reverend Arthur Smyth.

The Cavendish family was at the heart of the Whig party that dominated politics, and a career in politics was the inevitable destiny for Cavendish, as heir to one of the premier dukedoms in the country. As soon as he came of age he was elected to the House of Commons in May 1741 as MP for Derbyshire, the family seat, and adopted his father's allegiance to the prime minister, Sir Robert Walpole. After Walpole's resignation in 1742, he sided with Walpole's political heirs, the Pelham faction, led by Henry Pelham and his brother the Duke of Newcastle, and strongly supported their attempts to fashion a viable administration over the next four years.

On 27 March 1748 Cavendish married Lady Charlotte Elizabeth Boyle, Baroness Clifford of Londesborough (1731-1754), the third but only surviving daughter of Richard Boyle, third Earl of Burlington (1694-1753), and his wife, Dorothy Savile (1699-1758). The match had been planned during the couple's childhood, although Cavendish's mother disapproved. Despite her fears, the marriage proved to be happy, albeit short; Charlotte died of smallpox six years later, on 8 December 1754.

They had four children: William Cavendish, later fifth Duke of Devonshire (1748-1811); Dorothy (1750-1794), who married William Bentinck, third duke of Portland; Richard (1752–1781), MP for Lancaster and then Derbyshire; and George (1754–1834), MP for Knaresborough, then Derby, who became first Earl of Burlington of the second creation in 1831. It was a politically advantageous marriage, as Charlotte's inheritance on her father's death in 1754 included vast estates in Yorkshire and Ireland, as well as electoral interests over the two parliamentary seats at Knaresborough and the Irish parliamentary constituency of Lismore Town. Burlington's villa at Chiswick, and Burlington House in Piccadilly also passed into the Devonshire family. Burlington was an architect and a great connoisseur of the arts, and the inheritance also included his library (containing many important architectural books and drawings), as well as many paintings and the entire contents of his houses.

With his political standing enhanced by his marriage, Cavendish took his seat in the Lords in 1751, which enabled him to accept the mastership of the horse and a cabinet seat from Pelham; he had earlier declined the governorship of the new Prince of Wales, the future George III. He was appointed to these offices and sworn of the privy council on 12 July. Following Pelham's death in 1754 he adhered closely to Newcastle, who appointed him lord lieutenant of Ireland in March 1755. He outlined his policy of reconciling the rival factions in Ireland in a letter to Newcastle, dated 4 October 1755: 'My scheme is if possible to govern this country without a party and make those that receive favours from the Crown think themselves obliged to it and not to their party here'. His policy paved the way for the decisive viceroyalty of the fourth Viscount Townshend in the 1760s.

On 5 December 1755 Cavendish succeeded as fourth Duke of Devonshire. He returned to England in October 1756 at a time of conflict with France and political instability at home. Fox's resignation that month triggered the end of Newcastle's administration, which had been worn down by military failures. Pending a more permanent arrangement, whereby William Pitt could be reconciled with Newcastle, George II summoned Devonshire to form an interim ministry to avert government collapse and to manage the war with France. On 6 November, Devonshire was appointed First Lord of the Treasury (or Prime Minister) and Pitt succeeded Fox, who had been unable to form a viable ministry, as Secretary of State for the South.

However, the Devonshire/Pitt ministry proved short-lived, and it was fatally damaged in April 1757 when Pitt resigned, along with his cousin Temple. After two months of protracted negotiations the Newcastle/Pitt coalition succeeded to office on 29 June, a coalition that led Britain to victory over France.

Devonshire became Lord Chamberlain in the coalition but retained a seat in the inner cabinet, where his integrity, family standing, and friendship with leading Whigs allowed him to calm the rancour of party politics and personality differences. This was especially important after the accession of George III in October 1760 and the advent of his mentor, Lord Bute, whose rapid advancement threatened to undermine Whig hegemony and destabilize governmental politics. Throughout 1761 and 1762, during the peace negotiations with France, Devonshire was a key factor in maintaining the ministerial harmony necessary for achieving peace. During the momentous months from September 1759 to October 1762 he kept a diary which offers keen insights into the decision-making process and general diplomatic affairs of the time.

When Newcastle resigned in May 1762 Devonshire did not follow him out of office but showed his solidarity by refusing to attend cabinet. This anomalous situation, whereby he retained his office yet absented himself from the business of government, could not be tolerated for long, and following a disagreement with Bute over the final peace treaty, he resigned as Lord Chamberlain on 28 November 1762. George III expressed his extreme displeasure at his conduct a few days later when, with his own pen, he struck Devonshire's name from the list of privy councillors, a rare gesture that ended Devonshire's political career. In October 1764, the King dismissed him as Lord Lieutenant of Derbyshire, an office that had been held continuously by the Cavendishes since George I's accession.

Outside of his political life, the Fourth Duke continued to build on changes made by his father to the gardens and park at Chatsworth: he appointed the architect James Paine to design a new stable-block to the north of the house, and an elegant three-arch bridge across the widened River Derwent which was angled to provide a striking view of the house from the entrance drive. Paine also designed a one-arch bridge and a water mill located in the south of the park, and made a number of changes to the house itself, creating the present North entrance in place of the former kitchen, and providing a new service range to the north (demolished by the Sixth Duke when the present North Wing was built in the 19th century). But the Fourth Duke's most important change was to call in the famous landscape gardener Lancelot 'Capability' Brown, to sweep away the First Duke's formal gardens around the house and to surround it with a carefully planned and planted romantic landscape.

The Duke's final months were spent at Spa, Germany, in a state of deteriorating health. He died there on 2 October 1764, aged forty-four, and was buried next to his wife in All Saints', Derby.

Reverend Richard Newcome was vicar of Hurley, Hampshire. He was tutor to Lord Hartington and Lord Brackley and afterward bishop of Llandaff and St Araph and rector of Whitchurch, Shropshire. He died at Bath in 1769 without children but several nieces and nephews.
