Montagu’s grandfather, a lawyer, acquired Boughton in 1528, and enlarged the estate with purchases of monastic lands, before rising to become lord chief justice under Henry VIII.
Montagu kept a journal of the Parliament, which shows him to have been conscientious in attendance. The surviving portions, covering the first and third sessions, appear to have been written up from notes or from memory, and were primarily intended as a record of the passage of bills, rather than of debates; he took particular note of legislation relevant to his public duties and local offices.
Montagu’s speech followed immediately after the exposition by Sir Robert Wroth I of a semi-official programme of reform devised by James I’s chief minister, Lord (Sir Robert) Cecil†; and Montagu was immediately named to two committees to consider his own proposals and those enumerated by Wroth.
Montagu was one of those ordered to attend the king over the disputed Buckinghamshire election (28 Mar.), to produce a written report of the Commons’ resolution (30 Mar.), and to confer with the judges (5 April).
On 14 May Montagu was granted privilege in connection with a lawsuit against Serjeants’ Inn, where he claimed certain property.
In August 1604 the king visited Boughton and ‘seemed to be very merry’.
At the opening of the second session Montagu was named to the privileges committee (5 Nov. 1605), and once proceedings resumed after the discovery of the Gunpowder Plot, he was appointed to consider how best to prevent future Catholic conspiracies (21 Jan. 1606), and to attaint the plotters (30 April).
On the fraught topic of purveyance, Montagu came out on 5 Mar. in support of composition, once more following the course most likely to please the king.
Montagu was less prominent in the third session. Reappointed to the privileges committee (19 Nov. 1606), he was subsequently named to a deputation to hear the Lords’ proposals on the Union (24 Nov.), although he was unimpressed with the manner in which the Commons accepted the peers’ invitation, which he afterwards told the diarist Robert Bowyer* was procedurally incorrect.
On the outbreak of enclosure riots in the Midlands in late May, Montagu was recalled from Westminster to Northamptonshire to help suppress the uprising. He had little sympathy with the protesters, for despite his recognition of the general hostility towards depopulation, as a landlord he was strongly impressed with the inconveniences of the open-field system.
After the third session Montagu returned to Northamptonshire and received the submissions of the rioters. He was appointed to a commission of inquiry, to which he was himself presented for making illegal enclosures.
When the Speaker commanded the Commons in the king’s name not to touch on the prerogative in the debate on impositions, Montagu was among those who observed on 11 May that since James was out of town the message could not have come from him directly; and he therefore successfully moved that ‘twas not fit for us to receive it; but [to] proceed as we should if no message had been sent at all’.
In response to the Lords’ request on 11 June to meet representatives of the Commons so that they might impart to them various matters on the orders of the king, Montagu was the first to take exception, pointing out that it was ‘unusual and derogatory from the ancient liberties of the House to receive a message from His Majesty by the higher House, as though they were interposed between the king and his subjects’.
In his own county Montagu came into conflict with Sir Anthony Mildmay† and the recusant Sir Thomas Brudenell, who was appointed keeper of two walks in Rockingham forest by the 1st earl of Exeter (Sir Thomas Cecil†) in 1612. Montagu, who had expected these offices to fall to himself, took great offence, but was unable to change the earl’s mind.
Montagu’s first appointment was to a committee to examine precedents for allowing the attorney-general to sit in the Commons following the return of Sir Francis Bacon (8 Apr. 1614), and later the same day, although he seems not to have been present at the time, Montagu was named to the privileges committee.
When Richard Martin*, speaking as counsel for the Virginia Company on 17 May, strayed from his topic to chide the Commons for its unco-operative attitude towards the king, Montagu voiced the disgust of many Members, condemning Martin’s speech as the ‘most unfitting ... most offensive and injurious’ he had ever heard, and moved that some action be taken on it.
An obscure quarrel with Sir Anthony Mildmay in 1615 seems to have left a legacy of bitterness between Montagu and Mildmay’s heir, Sir Francis Fane*.
Montagu was returned for Northamptonshire for the third and last time in November 1620. When his younger brother Sir Henry was ennobled in the following month, the king praised the whole family, and promised Montagu himself a title, though he ‘smelt a little of puritanism’.
Montagu was among those ordered to draft a petition for free speech (12 Feb.), and was named to a select committee to make a weekly inspection of the draft Journal (13 February).
When Parliament reassembled, Montagu maintained on 20 Apr. that Sir John Bennet*, judge of the Prerogative Court of Canterbury, who was accused of taking bribes, was not entitled to a summary of the charges against him; but three days later he conceded that the proposal to freeze Bennet’s assets was against the law.
The Floyd case was not Montagu’s only concern at this time. On 2 May he moved that the London poor relief bill should extend to the whole kingdom; otherwise it would drive paupers into the country.
Montagu was appointed to draft a petition of grievances (16 May), and his name headed the list of the committee for a bill to provide for catechizing children (16 May).
Although the king, in calling for an early end to the session, offered to pass any bills that were ready, Montagu advised the House against it. He gave as his reason that ‘it will better content the country, when as they shall understand that this is but a cessation, and that Parliament doth continue’. Any other course might prove dangerous, and he added that until the session was prorogued, rather than merely adjourned, ‘we still enjoy our privileges from arrest and the like, as if we did still sit in Parliament’.
Montagu’s career in the Commons ended with the adjournment. On 29 June he was created Baron Montagu of Boughton, and when the autumn sitting commenced he was summoned to the Lords. His journals of proceedings in the upper House survive for the autumn sitting of 1621, and for the Parliaments of 1624, 1625, 1626, 1628, and 1640-1, together with various copies of notable speeches in the Commons.
The Forced Loan was fiercely opposed in Northamptonshire, even by a majority of the gentry, but Montagu committed himself to enforcing the Loan commission.
