The young Viscount Dungarvan [I], as Charles Boyle was styled after his father inherited the earldom of Cork [I] in September 1643, was sent to Oxford in the mid-1650s, where he was under the tutelage of John Locke and also came under the wing of his uncle, the natural philosopher Robert Boyle.
His parliamentary career began in the Irish House of Lords, to which he was summoned in January 1663 by a writ of acceleration. However, his attention turned to England in 1665 after his father was created earl of Burlington in the English peerage. From this point he was almost exclusively referred to, in English sources at least, by the courtesy title Lord Clifford of Lanesborough, a barony which had been conferred on his father by patent in 1644. In 1670 he entered the English House of Commons following a 1669 by-election for the borough of Tamworth. He had no personal connection with the region and gained his seat largely through the interest of his mother-in-law, the dowager duchess of Somerset.
From the time of the long prorogation of 1675–7, there were plans that Clifford of Lanesborough, ‘who is really an excellent patriot’, would take one of the seats for the county of Yorkshire, as his family’s principal seat in England, Londesborough Hall, lay in the East Riding of the county. Through the local influence and support of his father, Burlington, the incumbent Member, Conyers Darcy, later 2nd earl of Holdernesse, and the local worthies George Savile, earl (later marquess) of Halifax, and Thomas Belasyse, 2nd Viscount Fauconberg, he proceeded to sit as knight of the shire for the three Exclusion Parliaments, joined by Henry Fairfax‡, 4th Baron Fairfax of Cameron [S].
In 1687–8 he signalled his opposition to James II’s policies by standing as surety for the appearance of William Cavendish, 4th earl (later duke) of Devonshire, at his trial in king’s bench in May 1687, and by joining the crowd of supporters at the acquittal of the seven bishops.
This mistake having been rectified, Clifford of Lanesborough apparently saw little reason to remain in the House and he last sat in the first session of the Convention on 20 Aug. having been present for 18 of its sitting days since his first attendance. Classed by Carmarthen (as Danby had become) as among the supporters of the court in a list compiled between October 1689 and February 1690, he came to a full three-quarters of the sittings of the second (winter 1689-90) session, during which he was named to 11 committees. On 14 Jan. 1690 was a teller in the division on the motion concerning the treason trials Bill, ‘That it is the ancient right of the peers of England to be tried only in full Parliament for any capital offence’.
Clifford of Lanesborough was present at 64 per cent of the sittings in the 1690–1 session and was nominated to 22 committees. His, and indeed the Journal’s, use of the title Baron Clifford without the suffix ‘of Lanesborough’ brought up a long-standing dispute between the different branches of the Clifford family, which came to a head in this session. On 27 Nov. 1690 the petition of his distant cousin Thomas Tufton, 6th earl of Thanet, was read before the House, in which he argued that the ancient title of Lord Clifford, a barony created by writ in 1299, descended to him as the sole male heir general, after it had been held in abeyance among female heirs general from 1605 to 1676. Clifford of Lanesborough’s mother, Lady Elizabeth Clifford, countess of Burlington, submitted her counter-petition on 2 Dec. claiming the Clifford barony through her father, Henry Clifford†, 5th earl of Cumberland, who had been summoned to the House in 1628 by a writ of acceleration addressed to him as Lord Clifford. It was much later (in 1737) adjudged that the writ summoning Henry Clifford to Parliament in 1628 had been done in error and in effect created a new barony by writ, another Lord Clifford. At the time, though, there was still much doubt in peerage law about the position and heritability of baronies by writ and it was probably in order to clear up this uncertainty and to give a firmer base for claims to the Clifford legacy that Richard Boyle, Viscount Dungarvan [I], had been created Baron Clifford of Lanesborough by patent in 1644.
Parliament was prorogued on 5 Jan. 1691 without resolving this issue and the countess of Burlington died the day following the prorogation. Perhaps secure in his own possession of the barony of Clifford of Lanesborough, and confident that he would soon be inheriting the earldoms of both Cork [I] and Burlington, Clifford of Lanesborough assured the House on 8 Dec. 1691, in the following session of 1691–2, that he would ‘not obstruct the said claim’ of Thanet to the Clifford barony. Four days later the Committee for Privileges resolved that Thanet ‘was the sole lineal and right heir to Robert de Clifford and that the title and barony of Lord Clifford doth of right belong to him’.
He resumed his regular attendance in the 1692–3 session, being present at almost three-quarters of the sitting days and named to ten committees. This was, however, only one-fifth of the committees established on the days on which he was in the House and by this point the frequency of his nominations was declining sharply. On 4 Mar. 1693 it was proposed that he be added to the committee assigned by the committee of the whole House considering the state of the nation to draw up an address on the state of Ireland, yet even with his Irish background this fell through and his name does not appear in the list of committee members provided in the Journals.
Clifford died intestate at Londesborough on 12 Oct. 1694 and a few months later his estate was put into the administration of a creditor, while his father assigned many of the Irish lands which reverted to him to trustees to pay his son’s remaining debts.
