The Petre family rose through service at the Tudor court but were not ennobled until 1603. Their surviving papers for the seventeenth and early eighteenth centuries consist almost entirely of documents relating to the management of their estates and financial affairs; no personal or political archive is known to exist. The family’s major territorial base was in Essex, where they owned some 11,000 acres, mainly centred on Thorndon, Ingatestone and Writtle. They also held substantial tracts of property in Devon, with outlying properties in Dorset, Gloucestershire and East Anglia.
As Catholic peers, the Petres’ position in Essex society must have been somewhat difficult. The county was solidly protestant, with a substantial and vociferous Puritan minority. Petre had no electoral interest of his own, but his estates and position within the county made him a valuable ally for those who were seeking election, and he was on friendly terms with members of the county elite, including the Bramstons and Wisemans who had sent several family members to the Commons. However, his religion effectively barred him from the kind of office and influence that his extensive landholdings would otherwise have guaranteed. Petre’s principal country residence was at Thorndon Hall (assessed at 72 hearths in 1662); a smaller property at Ingatestone (assessed at 30 hearths in 1662) being occupied by his mother until her death in January 1685.
an ancient structure, built after the same plan as all the others in England, with a tendency rather to the Gothic and Rustic than to any chaste style of architecture but, as far as convenience is concerned, sufficiently well contrived. It is in a good situation, surrounded by a wall which incloses a large and green meadow; and among other things which contribute to its pleasantness, the deer-park, which extends to a distance of five miles, or more, is a most important addition to it. Its noble owner lives there with a magnificence equal to that of other peers of the kingdom, and in a style commensurate with his fortune, which is estimated at ten thousand pounds per annum.

That the 4th Baron Petre lived up to his rank is undeniable, but the extent to which his life style was genuinely ‘commensurate with his fortune’ is rather more questionable since it seems to have been based on extensive borrowing. Some of his misfortunes may have been of his own making, for he is known to have gambled for high stakes but the real threats were more difficult to control.
At his father’s death in 1638, Petre was unquestionably extremely wealthy. He had inherited personal estate estimated at some £30,000, of which £20,000 was held in liquid capital, and real estate producing a gross landed income of approximately £8,000 p.a. Between 1638 and 1660, his financial stability was threatened many times over. He was a minor in 1638, with the result that the estate had to bear the costs implicit in the processes associated with wardship. The wardship was bought for £10,000 by his father’s executors, who included his uncle, William Petre of Stanford Rivers, and another kinsman, Edward Somerset, then styled Lord Herbert, later 2nd marquess of Worcester.
Petre’s father and grandfather had each successfully raised large families, with the result that the estate was burdened with a number of settlements and annuities to provide portions for their younger children. Then, just as the estate was beginning to emerge from these difficulties, the events of the Civil War and the Interregnum created fresh turmoil. At some point after 1642, it was reported that both Northampton and Herbert had been ‘in actual war against the Parliament’ but that Petre was now living in Oxford with Francis Cottington†, Baron Cottington.
In 1649 Petre married Elizabeth Savage, who brought with her a portion of £5,000, paid in advance. They soon separated.
Elizabeth Savage’s dower was not enough to rescue Petre’s finances. In May 1652, desperate to preserve his estates and creditworthiness, he took the oath of abjuration, thus securing the return, without compounding, of his sequestered estates.
It was perhaps only to be expected that a peer who had suffered so much at the hands of the parliamentarians should be determined to take his place in the newly restored House of Lords. To the consternation of those who had hoped to reserve the House for the peers of 1648, Petre, along with Thomas Savage, 3rd Earl Rivers, Lionel Cranfield, 3rd earl of Middlesex and Richard Sackville, earl of Dorset, ‘got into the House’ on the afternoon of 26 Apr. 1660.
Petre attended the first (1660) session of the Convention for just over 56 per cent of sitting days. He was named to the committee for privileges and on 9 May was added to the committee for the reception of the king. He was present on 22 May and presumably therefore responsible for presenting a petition from his mother, the dowager Lady Petre, against the damage caused to her estate by sequestration and denying that she had ever been indicted or convicted as a popish recusant. The House held that as the widow of a peer she was entitled to privilege of Parliament and suspended proceedings against her ‘until the merits of her cause be fully heard and determined by the law.’ During a meeting of the committee for privileges held on 14 June and reported to the House on 16 June 1660, he testified that he had been present at the trial of Charles I and had heard Robert Danvers, described in the records of the House as Viscount Purbeck, describe the regicide John Bradshaw‡ as ‘a gallant man, the preserver of our liberties; and that he the said Lord Viscount Purbeck hoped that Bradshaw would do justice upon that tyrant (speaking of the late king).’
The first (1661-2) session of the Cavalier Parliament saw his attendance drop to just under 24 per cent, partly explained by patchy attendance during November and December 1661 followed by a long absence after 20 Dec. 1661 before his return to the House on 19 Mar. 1662. Such a prolonged absence may have been caused by illness as he was excused attendance at a call of the House on 25 Nov. by reason of sickness. In January 1661 he received a general pardon, although quite why he should have needed one is unclear.
The 1663 session saw him present for two-thirds of sitting days. He was absent on the first day of the session and so was not named to the committee for privileges until he was belatedly added on 9 April. He was, however, present and named to the committee for petitions when it was appointed on 25 February. He was named to a further five committees including the bill to settle differences between John Paulet, 5th marquess of Winchester, and his son Charles, then styled Lord St John (later duke of Bolton) on 1 June and (somewhat ironically given his own leisure pursuits) the bill against gaming on 26 June. Despite his earlier support for Edward Hyde, earl of Clarendon, in the matter of the Powell fines, in July Wharton predicted that would support the attempt of George Digby, 2nd earl of Bristol, to impeach Clarendon. The session ended on 27 July, but during the recess members of the House continued to be involved as mediators in the Winchester dispute, and in September Petre was one of the committee members who tried to mediate the quarrel.
Petre’s attendance over the short 1664 session rose to just over 83 per cent. He was named to the committee for petitions but not to that for privileges as he was absent when that committee was nominated. He was not in the House on 31 Mar. when his estranged wife claimed privilege against arrest for debt. Her petition sparked a debate about rights to privilege. Warwick Mohun, 2nd Baron Mohun, argued that her petition was defective since, as a married woman, she could not sue in her own name. Charles Howard, later 2nd earl of Berkshire but then styled Lord Andover and who sat in his father’s barony as Howard of Charleton, carried the House when he insisted that ‘their lordships ought not to take notice of anything but the breach of privilege, which he thought was manifest, for if their privileges extended to the protection of their servants a fortiori to that of their wives.’
Petre’s attendance for the 1664-5 session dropped to 58 per cent. Again absent for the opening of the session he was not named to the committee for privileges. He was named to only three committees. Between sessions he was present on 21 June 1665 when Parliament was again prorogued. He was then absent for the whole of the brief autumn 1665 session. Petre returned to Parliament on 21 Sept. 1666, the second day of the 1666-7 session. His attendance over the session reached nearly 79 per cent. He was named to the committee for privileges and to four other committees, including that for the bill to render illegitimate Lady Roos’ children on 14 Nov. 1666. On 23 Jan. 1667 he protested against the decision not to add a right of appeal to the king and House of Lords to the bill creating a court to resolve disputes arising from the Fire of London.
He was present on both the prorogation days but missed the first two weeks of the 1667-9 session, nevertheless recording an attendance of just over 75 per cent. His name was added to that of the committee for petitions on 20 Nov. 1667, and he was named to a further ten committees. Despite his high level of attendance there is no information about his voting intentions in the major issue of the day, the attempt to impeach Clarendon.
The next, 1669, session saw his attendance fall to just under 53 per cent. He missed the first two weeks of the session and was excused at a call of the House on 26 Oct. as being ill. Having missed appointment to the committee for privileges he was added to it on 10 Nov. and was named to one further committee. On 22 Nov. he was one of five peers who protested at the passage of the bill to restrict privilege and limit trials of peers, arguing that ‘the judiciary and other privileges of Parliament and peerage [are] … so fundamental, as we ought not to part therewith’.
Petre’s attendance recovered to nearly 65 per cent in the 1670-1 session. Present from the opening of the session he was named to the committees for privileges and petitions. He was named to a further 18 committees during the session including that preventing the growth of popery which was effectively a committee of the whole House. In February he was one of nine peers who voted against the decision to agree to the king’s request that proceedings relating to Skinner v. the East India Company be razed from the Journal.
Petre’s estranged wife had died in 1665; late in 1672 he remarried. His second wife, Bridget Pincheon, was some 25 years his junior, but it was not her age that caused a stir, rather that she was ‘of ordinary birth’ and either had no portion at all or an inconsiderable one.
Petre’s attendance reached just over 79 per cent during the brief session of 1673. Present from the opening of the session he was again named to the committees for privileges and petitions. On 5 Mar. he was named with almost everyone listed as present to the committee to provide a bill of advice to the king and in the course of the session to four other committees.
Early in January 1674 it was reported that, presumably as a result of the recent Test Act, Petre and other ‘popelings’ were planning to leave the country. The rumour proved to be unfounded. Petre took his seat at the opening of the 1674 session on 7 Jan. 1674 and was then present for nearly 53 per cent of sitting days. On 27 Jan. he was one of a number of Catholic peers who benefited from the ruling of the House that prosecutions for recusancy were covered by privilege of Parliament. Anti-Catholic agitation and the need to reassure his many creditors may well have been behind his decision in April 1674 to enter into another debt trust. Petre’s standard of living was maintained by continual borrowing. He owed over £11,000, slightly more than he had owed at the time of the debt trust of 1652.
Presumably in response to the deteriorating political situation Petre missed only four days of the first 1675 session. He was as usual named to the committees for privileges and petitions, as well as to a further three committees. Thomas Osborne, earl of Danby (later duke of Leeds) believed that Petre would support the non-resisting test, but on 21 Apr. together with Anthony Ashley Cooper, earl of Shaftesbury, and other opponents of the court he was one of the leading speakers against the proposition and entered a protest at the refusal of the House to throw it out.
The short autumn 1675 session saw Petre present on nearly 91 per cent of sitting days and named to the committees for privileges and petitions as well as three other committees. On 20 Nov. he again joined with Shaftesbury in seeking a dissolution in the aftermath of the dispute occasioned by the case of Sherley v. Fagg, entering a protest when the House resolved to reject the motion.
Continuing concern about Catholics and Catholicism kept Petre’s attendance high, nearly 89 per cent, throughout the 1677-8 session. Perhaps surprisingly, he remained on good terms with Shaftesbury, being listed by him as a doubly worthy papist. He was named to 25 other committees including, on 16 Feb., that for discovering the author and printer of the pamphlet Some Considerations upon the Question, whether the Parliament is dissolved by Prorogation for Fifteene Monthes. He held the proxy of Charles Howard, now 2nd earl of Berkshire, from 20 Feb. to 11 March. On 15 Mar. 1677 he entered a dissent to the passage of the act for further securing the protestant religion which also mandated the protestant education of the children of the royal family.
Petre was present at the opening of the first session of 1678 on 23 May. His attendance dropped back to 65 percent. He was named to the committees for privileges and petitions as well as that for the Journal and five other committees.
Petre’s catholicism and his association with known Jesuits made him particularly vulnerable when, during the recess over the summer of 1678, Titus Oates revealed a Jesuit plot to assassinate the king and to overthrow the English government. Oates testified on oath that he had seen Petre ‘receive a commission as lieutenant general of the popish army destined for the invasion of England…’
Inter House wrangling over the proper procedures for impeachments, whether the popish lords should be tried before or after Danby and the proper role of the bishops meant that Petre was never tried. In December 1683 although seriously ill he was refused permission to leave the Tower for a change of air.
At his death the title passed to his younger brother John, but the estates were seriously depleted by the handsome provision (£10,000 secured against his unencumbered western estates and protected from his creditors) that Petre made for his only daughter, Mary, who later married George Heneage of Hampton, Lincolnshire.
