Born into an important Leicestershire family, Beaumont was the younger brother of Sir Henry Beaumont I, who inherited the family estates at Coleorton. He established himself in his native county by acquiring through marriage the manor of Stoughton, three miles south-east of Leicester, which he vigorously improved, converting 20 acres at Stoughton to pasture and exploiting coal deposits in Warwickshire and Nottinghamshire (not always profitably) in partnership with his son-in-law, Sir John Ashburnham, and Sir Percival Willoughby*.
Beaumont was nominated for Leicester in 1597 by the 4th earl of Huntingdon, only to be rejected as ‘an encloser himself, and unlikely to redress that wrong in others’.
Beaumont was certainly appointed on 24 Mar. 1604 to the committee to recommend expiring laws for continuance or repeal, as Sir Thomas Beaumont II was not returned for another three days.
In the second session Beaumont was joined by his elder brother, Sir Henry, who was elected senior knight of the shire for Leicestershire on 6 Feb. 1606. He continued to show an interest in religious issues, for on 22 Jan. he was appointed to the committee ‘to consider of the fittest course to provide for the general planting of a learned ministry’ and to combat non-residence. Seven days later he was named to the committee for the Sabbath observance bill. In the aftermath of the Gunpowder Plot he urged, rather impractically on 3 Feb. that measures should be taken to prevent recusants from keeping house, and on the same day he was named to attend the conference with the Lords about the recusant laws. He was subsequently named to committees to consider bills for ‘the better direction of ecclesiastical proceedings’ (1 Apr.) and ‘against such as coming to church do refuse to receive the sacrament’ (7 April). On 3 Apr. he was among those ordered to confer with the Lords about ecclesiastical grievances.
On 31 Jan. 1606 Beaumont produced the navigable rivers bill from the previous session, which had never been reported, and it was given a first reading. After the second reading on 7 Feb. he was named to the committee.
Beaumont was named to just six committees in the third session. He showed only a very limited interest in the Union, the main business of the session: on 28 Nov. 1606 he was added to a committee to prepare for a conference with the Lords and on 16 Feb. 1607 he opposed the expulsion of Christopher Piggott for insulting the Scots.
By 1607 there were signs of growing tension between Beaumont and the 5th earl of Huntingdon, the head of the Hastings family who had recently come of age and replaced Beaumont’s elder brother, Sir Henry I, as custos rotulorum of Leicestershire. Probably as a consequence, Beaumont drew closer to the 1st Lord Grey of Groby (Sir Henry Grey†), Huntingdon’s rival for dominance in the county. Beaumont tried to block the appointment to the bench of Huntingdon’s great-uncle and confidant, Walter Hastings, in the summer of 1607. Beaumont objected to Walter because the latter was widely suspected of harbouring Catholic sympathies. In a letter to Huntingdon he declared that Walter was ineligible for office owing to his wife’s recusancy, claimed that he knew the appointment ‘to be against the mind of the Parliament’, and added that ‘if he lived to the next session it should be amended’. Beaumont also clashed with Huntingdon over Leicestershire’s local composition for purveyance. Indeed, the earl, who took over responsibility for raising this money in 1607, subsequently claimed that he had been consistently opposed by Beaumont.
In December 1607 Beaumont was compelled to bring an action in Star Chamber against a former servant, Coleman, who had sought revenge for his dismissal by claiming intimacy with his wife and daughters. Repetition of these stories was encouraged, if not instigated, by Walter Hastings’ son, the openly Catholic Sir Henry Hastings of Braunston, whom Beaumont had presented as a recusant at the local quarter sessions for a month’s absence from church and allegedly over-assessed for the subsidy. Hastings claimed that Beaumont was acting in collusion with his own Protestant cousin and namesake, Sir Henry Hastings*, against whom he had suits pending in the duchy of Lancaster court. Coleman was whipped, pilloried, and sentenced to life imprisonment, but escaped. However, sensational as the case was, its impact on county politics was probably mitigated by the refusal of Huntingdon and even Walter Hastings to support the allegations against Beaumont.
There is no evidence that Beaumont pursued his complaint against the appointment of Walter Hastings when Parliament resumed in 1610, but he was more prominent in the fourth session than he had been before. It is possible that he was added to the privileges committee, for although not recorded among those added to the committee at the beginning of the session he was listed as a member on 11 May, when the committee was ordered to draw up an order about receiving messages from the king.
On 22 May Beaumont expressed the House’s alarm at the king’s claim that the right to levy impositions formed part of his prerogative when he stated that there was ‘a fear, that our whole liberty be swallowed up’. He was named to a committee appointed to draw up a petition to the king about the subject on 3 July.
Returning to Westminster for the fifth session, Beaumont argued on 2 Nov. 1610 that the Commons could only give a conditional reply to the king’s message about the Contract. He seems to have been unsure whether the concessions promised in the last session were still on the table and whether they would be binding. He was also concerned how the money to be paid to the king in compensation would be raised.
Beaumont was one of the 30 Members summoned on 16 Nov. to an audience with the king, at which he ‘showed the greatness of impositions’.
Beaumont’s parliamentary career earned him a very mixed reputation. Sir William Heyricke* wrote in 1614 that Leicestershire ‘got as good an opinion in the House the last Parliament by Sir William Skipwith* and Sir Thomas Beaumont the elder as any shire or county in England’.
