The relationship between the first duke of Newcastle and his son, who before his succession to the peerage was styled variously Viscount Mansfield and later earl of Ogle, does not seem to have been a close one. Nevertheless, Mansfield appears to have been greatly influenced not only by his father’s staunchly Cavalier political sympathies but also by the first duke’s profoundly conservative perception of society and politics.
Early career 1660-76
Mansfield owed his place as heir to the dukedom of Newcastle to the death of three older brothers, the last of whom, Charles Cavendish, who had also been styled Viscount Mansfield, died in the early summer of 1659. After the Restoration, Mansfield represented first Derbyshire and then Northumberland in the Commons. His election to Derbyshire had been subject to a challenge and Mansfield’s life was threatened by one of his competitors. Mansfield’s father sought the assistance of Edward Hyde, earl of Clarendon, in ensuring that justice was done to his son.
In January 1666 it was rumoured that Ogle was on the point of being summoned to the House of Lords, though it was not specified whether this was by writ of acceleration or by virtue of a new barony to be conferred on him. The report encouraged Charles Howard, earl of Carlisle, to propose his heir for Ogle’s seat in the Commons but in the event Ogle remained where he was.
At the opening of 1670 Ogle was able to negotiate a highly advantageous marriage for his eldest daughter, Elizabeth, with the heir of George Monck, duke of Albemarle.
Duke of Newcastle 1676-85
Ogle succeeded to the dukedom on Christmas day 1676. Soon after inheriting the peerage he promised his support to Danby (as Osborne had become) in employing his interest at Berwick on behalf of Danby’s son, Peregrine Osborne, Viscount Dumblane [S] (later 2nd duke of Leeds).
Newcastle took his seat in the upper House on 15 Feb. 1677, the first day of the new session. He had previously appealed to Danby for financial assistance, lauding him as someone who had ‘been much more than his father to him.’
At the beginning of July Newcastle set out for his northern estates.
Family preoccupations continued to dominate Newcastle’s affairs into the early months of 1678. In February it was rumoured that his son, Henry Cavendish, now styled earl of Ogle, was either about to or had already married the Percy heiress. In the event the marriage was not settled until the spring of the following year.
Newcastle’s absence from both court and Parliament did not prevent him from being labelled triply vile by Anthony Ashley Cooper, earl of Shaftesbury. As a long-standing friend of Danby’s, the reason for such a classification is readily apparent. Given the relationship between the two men it appears at first surprising that Newcastle made so little effort to rally to his friend’s support after the lord treasurer’s fall.
News of the dissolution in January 1679 brought further requests from Danby that Newcastle would employ his interest on behalf of suitable candidates in the elections. He hoped that Newcastle would promote his heir, Ogle, as one of the county members for either Nottinghamshire or Northumberland, not least as he hoped it would bring father and son to London in time for the new Parliament. Newcastle proved once again disinclined to heed Danby’s renewed requests for his assistance.
Despite his extensive territorial interests in the Midlands and the north, Newcastle took little discernible part in the elections to the second Exclusion Parliament. This should not, however, be taken to indicate a lack of concern for his duties as lord lieutenant of Northumberland and Nottinghamshire. He responded swiftly to an order for raising Northumberland’s militia to oppose the Covenanters’ Rebellion, for which he received the thanks of the king.
Such matters appear to have remained of greater importance to Newcastle than parliamentary business. In October 1679 he wrote to Danby of his unwillingness to attend the new Parliament, asserting that he was ‘so crazy, I am fit for no place but what is very private and retired’.
Newcastle’s health appears to have improved by August 1680. Towards the end of the month he wrote to Danby assuring the former treasurer that, although he did not expect the new Parliament to last longer than ten days and that he would prefer not to make the journey, he would ‘most readily go and do your lordship all the service that shall lie in my power’.
In January 1681 Newcastle was summoned to a meeting with the king which Newcastle anticipated would lead to an offer of one of the great offices of state, possibly one of the secretaryships. Newcastle’s prediction appears to have been correct but even so he declined the king’s offer. This was perhaps due to his belief that he would be accorded only minor influence in the king’s counsels when compared with Halifax and to the fact that, as he confided to his friend Sir John Reresby‡ during their journey from London in February, ‘he liked not the measures then on foot, and thought the times but slippery’. Newcastle appears to have been increasingly envious of Halifax and resented the fact that his former friend had not warned him of the imminent dissolution. Danby, on the other hand, had advised Newcastle that Parliament was shortly to be dissolved, thereby helping him to retain Newcastle’s loyalty to his cause.
Newcastle took his seat in the new Parliament at Oxford on 21 Mar. 1681 and proceeded to attend on each of the brief session’s seven days. When approached shortly before the opening to support Danby’s attempt to secure bail, Newcastle not only offered to act as surety, but also desired to be allowed to introduce Danby’s petition for bail into the Lords.
Aside from his commitment to Danby’s cause, Newcastle’s attentions were increasingly dominated by overseeing affairs in the counties where he had influence. The summer of 1681 found Newcastle noted among those thought likely to sign the Derbyshire address. His efforts to recommend the Northumberland address to the local magistrates and deputy lieutenants, though, met with opposition and a rival address was penned by Sir John Fenwick‡. Such actions served to encourage Newcastle’s conviction that his position was being undermined and he pointed to Halifax as one of those he believed to be working against him. He was later to complain that his lack of interest at court prevented him from nominating a sheriff of his choosing.
Newcastle’s earlier inauspicious correspondence with Latimer did not prevent an attempt to unite the two families with the marriage of Latimer to one of Newcastle’s daughters. Latimer himself seems to have been unimpressed by the scheme and dismissed his would-be bride, Lady Frances, as ‘both sickly and peevish’. His father, Danby, was more disposed to press on with the alliance, provided that Frances Cavendish could have children. By the end of August Latimer appears to have been subjected to a beauty parade of all of Newcastle’s unmarried daughters. He remained unpersuaded but in the event the negotiations seem to have faltered because of the resolution of one of Newcastle’s daughters not to marry (or not to marry Latimer) and of the others being unavailable.
Tory reaction 1682-5
If Newcastle struggled to cope with his family’s travails, he proved far more assured in his support for the court in the aftermath of the Exclusion Crisis when he became an active agent of the Tory reaction. His political influence was greatest in Northumberland and Nottinghamshire and it was in these counties that he chose to concentrate his political efforts. In the summer of 1682 he was in close contact with Carlisle over the appointment of a sheriff in Northumberland and in September he was ordered to take up residence at Nottingham Castle to help quell disorders in that city.
Newcastle’s concerns extended beyond these boroughs to the general state of the two counties of which he was lord lieutenant, most notably at the time of the revelations of the Rye House Plot when he took a leading role in organizing the response of Nottinghamshire and Northumberland.
James II, the Revolution and after, 1685-91
After the failure to settle matters earlier, the final year of Charles II’s reign found Newcastle engaged with finalizing details of a marriage settlement between his daughter, Catherine, and Thomas Tufton, earl of Thanet. This was completed by the end of the summer.
Newcastle supported two Tory candidates at the Derbyshire election and also seems to have encouraged Reresby to contest York, but his role in the return of members for Northumberland is more obscure.
Though active during the elections, Newcastle was (typically) reluctant to attend the meeting of the new Parliament. He wrote to Halifax in February that ill health would prevent him from travelling to London. By April he had altered this resolution and though ‘hardly able to creep’ was determined not to seek permission to absent himself. Even so, he reckoned that he would struggle to attend many sittings ‘I am so very infirm.’ He waited on the king later that month and took his seat at the opening of the 1685 session.
Having returned to his estates much of Newcastle’s time was occupied by continuing negotiations for settling the affairs of his remaining unmarried daughters, who by the loss of his son were now coheirs to his considerable fortune.
As a distraction from his tempestuous family life, Newcastle continued to undertake those duties associated with his offices in the Midlands and north east over the next two years. He took steps to secure Nottinghamshire and Northumberland at the time of the Monmouth Rebellion and took an interest in the corporate politics of Newcastle and Nottingham.
It may be that a combination of personal pique and concern over the direction of affairs under the new monarch explains Newcastle’s declining enthusiasm for local politics. Reresby noted that upon meeting Newcastle in September 1685 the duke ‘made … free of his discourse in relation to affairs at court, and declared positively that he would not repair thither any more, and should be glad to be out of all manner of public employment’. This may indicate a degree of concern on Newcastle’s part as to the intentions of James II and his ministers, but Reresby also recorded that Newcastle’s freedom of expression was rooted at least in part in the ‘neglect’ he believed he had suffered when last at court, and in the failure to promote his soldier son-in-law, Albemarle. In another conversation with Reresby in August 1686 the duke made it clear that ‘he was very sensible of the king’s going on very fast in the promoting of his own religion, but [he], did resolve to be very loyal, and yet firm to his religion’.
It may be that it was an awareness of the potential conflict between his loyalties to the king and to the Anglican church which prompted Newcastle to take a step back from political activity, though his declaration to Halifax that ‘I resolve never to go to London. No Parliament can bring me there’ probably reveals little more than his usual unwillingness to attend the House of Lords.
Contemporaries clearly believed that any concern that Newcastle experienced regarding James II’s plans to repeal the penal laws and test acts would be over-ridden by his loyalty to the crown. During 1687 Newcastle was included in three lists forecasting the likely attitude of peers to James II’s campaign. Two of these classed the duke as a likely supporter of James and only one expressed any doubts as to his sympathies. This was reflected in a report from November 1687 of Newcastle’s message to his deputies in Nottingham that he intended, as he always had, to comply with the king’s desires.
If Newcastle did harbour private reservations as to the precise goals of James’s policies, his loyalty to the Stuart monarchy won out during the events of late 1688. In October he was one of those to offer to raise a force out of his own pocket. He was retained in his posts of lord lieutenant of Northumberland and Nottinghamshire and, following his offer, was also authorized to raise a new regiment.
Assessments of Newcastle’s behaviour at this time have been critical, though it has also been pointed out that a change of stance might have seriously affected his credibility.
very loyal and firm to his master the king, and consequently as angry against the earls of Danby and Devonshire, and such others as had been the actors in those parts for the Prince of Orange. He said he would be loyal to the king, firm to his religion, and act always according to law … He told me he had received a letter of summons to be at the Convention, but that he would not go nor act in that assembly; that he had offered to surrender the commission of his lieutenancies into the king’s hands before he went, but the king would not receive them; and that he would act so long as he might do it by them, but would not take any commissions from the prince or any such authority.Reresby Mems. 544-5.
Newcastle accordingly resigned his offices and declined a summons to attend the Convention. In November 1689 he undertook to send two servants to testify to his inability to attend, ‘the truth being he is a dying body.’ Even so he survived for long enough to refuse the oaths to the new regime in 1690. He also declined involving himself in the early stages of the dispute arising out of the Albemarle inheritance dispute.
Newcastle spent the remainder of his life in retirement at Welbeck, where he died on 26 July 1691.
