Wentworth’s grandfather served Henry VIII as chief porter of Calais, and was granted Lillingstone Lovell in 1546. Having trained as a lawyer, Wentworth became standing counsel to the city of Oxford in 1603 in succession to George Calfield†. Since the recorder, Robert Atkinson†, was disqualified from Parliament as a recusant, Wentworth also succeeded Calfield as the city’s junior representative in the first Jacobean Parliament. Perhaps with the intention of emulating his father, the notorious defender of the Commons’ freedom of speech during Elizabeth’s reign, he sprang into action on the opening day of business (23 Mar. 1604) when he reproached the House, ‘for the infirmities of it, in lacking some of the Members; another, for the deformity, having more than it ought to have, viz. certain burgesses newly appointed for the universities’.
In 1605 Wentworth lent Oxford corporation £100 towards the cost of obtaining a new charter and entertaining the king on a royal visit to the city.
In the third session Wentworth was appointed to the conference with the Lords about the instrument of the Union on 24 Nov. 1606, and on 5 Dec. he raised several legal points concerning escuage, a form of feudal tenure in the borders of England and Scotland which James proposed to abolish. He was among those ordered to prepare for another conference on 11 December.
In addition to the Union, Wentworth was occupied by a wide range of other business in the third session. He was added to the committee for another corporation grants bill (21 Nov. 1606), and in debate on 2 Dec. offered two provisos.
During the fourth session Wentworth emerged, in Notestein’s phrase, as ‘almost the watchdog of those in opposition’ to royal policy.
Having called for a debate on impositions on 1 May, Wentworth was the first to rise to reply to the message of 11 May, supposedly from the king, which ordered curtailment of debate on the prerogative. He did so by going onto the offensive: ‘is not the king’s prerogative disputable? ... Nay, if we shall once say that we may not dispute the prerogative, let us be sold for slaves’.
During the brief fifth session Wentworth continued in the forefront of the campaign against the royal prerogative. On 2 Nov. 1610, during a debate on impositions, he claimed that ‘if the king have a power over the laws, we cannot have security, therefore we must see if the law can bind the king’.
Wentworth’s services to Oxford’s corporation irritated his former university, which was frequently in dispute with the town. Indeed, the scholars took to terming him ‘Master Wantworth’, and in 1611 he was discommoned, with the effect of cutting him off from all intercourse with the university. However, he was restored three years later.
When Parliament met again in 1614, Wentworth was added to the committee for privileges (9 April). On 11 Apr. he suggested a conference with the Lords to debate the eligibility to sit of the attorney-general (Sir Francis Bacon*).
On 12 May Wentworth and three other lawyer-Members were ordered to investigate certain legal issues concerning impositions. He was subsequently appointed to help manage a conference on impositions.
Between 1617 and 1620 Wentworth was chiefly concerned with Oxford’s efforts to obtain a further charter.
Wentworth’s first appointment was to draft a bill for the reform of London’s prisons (3 Mar. 1621).
The majority of Wentworth’s speeches during the first sitting concerned legal or procedural matters. On a bill concerning juries he suggested that ‘jurors must be returned not where they dwell but where their land lies’, and was appointed to the committee (19 April).
The old fire burst out when the House met again in the autumn. On 3 Dec. 1621, in response to the proposal to marry Prince Charles to a papist, Wentworth urged Members to read again the official account of the Gunpowder Plot, for ‘these walls (methinks) do yet shake at it’. He believed it was warranted to petition the king on such an important matter, since ‘God himself doth direct us to petition Him for matters of His own glory and our good; methinks then it should be suitable to petition God’s lieutenant’. Against Sir Edward Sackville*, who had dismissed the possibility of any danger to the prince’s own faith, he pointed out that ‘the wives take up a great part and room in the husband’s heart’. He cautioned that the petition should, however, be ‘so far qualified as that we press not for an answer, but only express our fears and so leave it to His Majesty, and then I hope he will not take it offensively. There are some among us who act the devil’s part by making dissension between His Majesty and this House, and laugh at it when it is done’.
In 1624 Wentworth was re-elected without challenge. On 24 Feb. he insisted, in the face of vehement denials from Sir Edward Coke*, that the concealments bill took more from the king than was intended.
Wentworth was re-elected to Charles I’s first Parliament, but he played a far less prominent role in proceedings than he had under James. His main priority continued to be religion. His appointments included the committee for privileges (21 June 1625), and bill committees concerned with the Sabbath (22 June) and recusants (23 June). He was also ordered to help draft a petition on religion (24 June), and to consider a bill to remove benefit of clergy in some cases (25 June).
Wentworth was elected to his last Parliament in 1626. He was named to the committee for privileges (11 Feb. 1626) and numerous others, including those for the bills against simony (which covered the universities, 14 Feb.) and unworthy ministers (15 February).
Wentworth had been a keen advocate of war with Spain and despite recent military setbacks was anxious to continue fighting in the Protestant cause. He was therefore frustrated by the Commons’ constant recriminations over the affair of the St. Peter, a French ship unlawfully detained by the lord admiral, the duke of Buckingham. Rather than dwell on this matter, he urged (10 Mar.) that ‘the unum necessarium at this time is the security of ourselves from our provoked enemy ... howsoever things have been hither miscarried’.
Wentworth was dead by September 1627.
