Described by the Oxford antiquary Thomas Hearne as ‘a subscriber to Homer and a great proficient in Greek and all polite learning’, Carteret succeeded to the peerage when he was just five years old.
Before he attained his majority, Carteret’s fledgling political influence was noted in a list of clergy thought likely to vote in the 1705 election for Bedfordshire, where he was recorded as the patron of Mr Leith, incumbent of the parish of Bedford (though it was also noted that Leith owed some allegiance to John Ashburnham, Baron Ashburnham, a relatively new force in the county).
Carteret was noted as underage in a 1708 list of party classifications and again at the time of the Sacheverell trial two years later. From March 1710 he was believed to be actively courting Frances Worsley, granddaughter of Thomas Thynne, Viscount Weymouth.
In the spring of 1711, while still technically underage, Carteret began to exert his interest in the West Country as a rival to his kinsman, George Granville, Baron Lansdown, putting himself forward as one of the contenders for the vacant lieutenancy of Cornwall. Although Lansdown professed to have ‘as much tenderness for him as anybody can have’, he succeeded in impressing on Harley the dangers of humouring Carteret on this point, as ‘it would be making the queen take part in a private cause and give a decision which I am sure can otherwise never be in his favour’.
A little over a month after his 21st birthday, Carteret took his seat in the House in the closing stages of the first session of the Parliament that had commenced the previous November. He was present on 11 of the remaining days (his first sitting coinciding with Robert Harley’s introduction as earl of Oxford). That summer he was employed by Oxford as an intermediary with his father-in-law, Weymouth, whose support Oxford wished to ensure with the offer of a step in the peerage. Weymouth proved unwilling to accept the proffered earldom. He was also said to have declined promotion to a marquessate some years earlier.
Carteret suffered the death of an infant daughter within days of her birth in the early autumn but, despite his loss, he assured Weymouth of his intention of being at the opening of Parliament, being unwilling to ‘sneak the first day’. Further disagreements with Lansdown also occupied his attention at this time over the presentation to one of the family’s West Country livings. Carteret wished to give the place to a school acquaintance but Lansdown had already promised it to a kinsman, Chamond Granville, whom Offspring Blackall, bishop of Exeter, had proved ‘exceeding hasty’ in installing in the parish.
Carteret joined his father-in-law (whose ‘council and direction’ he openly professed to rely on during this period) in taking his seat at the opening of the new session on 7 Dec. 1711, after which he was present on almost 84 per cent of all sitting days.
Despite his early association with Oxford, by the beginning of 1712 (presumably through his father-in-law’s influence) Carteret had drifted away from the lord treasurer and into Nottingham’s orbit. On 2 Jan. he joined with Nottingham and Weymouth in voting against the ministry’s motion to adjourn, though the ministry carried the vote through the employment of Scots votes and those of the newly created peers.
Three weeks later Carteret chaired the committee considering the Van Homrigh estate bill, which he reported to the House on 25 Mar., and on 19 May he again acted as teller for the division on the question of whether the land grants bill should be committed. On this occasion the ministry (opposing the motion) was defeated by the narrowest of margins and it proved necessary to count the proxies twice, as the tellers were not in agreement after the first tally. The final reckoning was 74 in favour and 73 against the motion.
The death of Carteret’s young kinsman William Henry Granville, 3rd earl of Bath, in 1711 proved the catalyst for further divisions within the family and led to Carteret, his mother, his cousin John Gower, 2nd Baron Gower (later Earl Gower), and another cousin, Katherine Peyton (for whom Carteret acted as guardian), bringing an action in queen’s bench against Lansdown in October 1712 for failing to divide the Bath estate among the heirs. Lansdown maintained that he was the sole heir as the only direct male descendant of the first earl.
In the midst of these family disputes, Carteret continued to be actively involved in the heated political debates of the closing years of Anne’s reign, but, in spite of his consistent opposition to Oxford’s ministry the previous year, in March 1713 Swift assessed him as a likely supporter of the government in the forthcoming session. He took his seat on 9 Apr., after which he was again present on approximately 84 per cent of all sitting days. On 8 May he was noted among ‘3 or 4 Tory lords’ to have been the only objectors to the passage of the commissioners of accounts’ bill.
Carteret was missing from the opening days of the new Parliament but he returned to the House a week into the first session on 23 Feb. 1714. He was present thereafter on 77 per cent of all sitting days, during which he again chaired a committee for a private estate bill (that of Richard Coote, 3rd earl of Bellomont [I]). Absent from town over the Easter period, Carteret was expected to return on Easter Monday, after which he persisted with his association with the whimsicals.
Although he had at one stage been one of Bolingbroke’s dining companions, Carteret’s warm support for the Hanoverian succession prevented him from backing the secretary in his manoeuvrings against Oxford.
The agreement also held a further incentive, which was that it simplified matters with regard to the ongoing parallel dispute between Bath’s heirs and Ralph Montagu, duke of Montagu, over the Albemarle inheritance.
Carteret continued to thrive under both George I and George II, who valued his intellect and interest in foreign affairs. Through his loyalty to the dynasty he acquired a reputation as being unusually pro-German but he failed to achieve the kind of dominance of domestic politics demonstrated by the Pelham brothers or Robert Walpole* [192], later earl of Orford.
