He became a Member of Parliament in 1701, representing the family borough of
Wootton Bassett in
Wiltshire, as a Tory. His seat was
Lydiard Park at Lydiard Tregoze, now in the
Borough of Swindon. He attached himself to
Robert Harley (afterwards Lord Oxford), then
Speaker of the House of Commons, and distinguished himself by his eloquence in debate, eclipsing his schoolfellow,
Robert Walpole, and gaining an extraordinary ascendancy over the
House of Commons. In May, he had charge of the bill for securing the Protestant succession; he took part in the impeachment of the Whig lords for their conduct concerning the
Partition treaties, and opposed the oath of loyalty against the "
Old Pretender". In March 1702, he was chosen commissioner for taking the public accounts. After Queen
Anne's accession, St John supported the bills in 1702 and 1704 against
occasional conformity, and took a leading part in the disputes which arose between the two Houses. In 1704, St John took office with Harley as
secretary at war, thus being brought into intimate relations with
John Churchill, 1st Duke of Marlborough, by whom he was treated with favour. In 1708, he left office with Harley on the failure of the latter's intrigue, and retired to the country till 1710, when he became a
privy counsellor and
secretary of state in
Harley's new ministry, representing
Berkshire in parliament. He supported the bill for requiring a real property qualification for a seat in parliament. In 1711 he founded the Brothers' Club, a society of Tory politicians and men of letters, and the same year witnessed the failure of the two expeditions to the
West Indies and
to Canada promoted by him. In 1712, he was the author of the bill taxing newspapers. The refusal of the Whigs to make peace with France in 1706, and again in 1709 when
Louis XIV offered to yield every point for which the allies professed to be fighting, showed that the war was not being continued in the national interest, and the Queen,
Parliament and the people supported the ministry in its wish to terminate hostilities. Because of the diversity of aims among the allies, St John was induced to enter into separate and secret negotiations with France for the security of British interests. In May 1712, he ordered
James Butler, 2nd Duke of Ormonde, who had succeeded Marlborough in command, to refrain from any further engagement. These instructions were communicated to the French, though not to the allies, Louis putting
Dunkirk as security into possession of England, and the British troops deserted their allies almost on the battlefield. Subsequently, St John received the congratulations of the French foreign minister,
Jean-Baptiste Colbert, marquis de Torcy, on the French victory over
Prince Eugene at
Denain (24 July 1712). , together with a portrait of

House of Commons. The treaty was presented in the Commons by
Arthur Moore as St John had been created Viscount Bolingbroke earlier that year. A major campaign was waged against its approval under the slogan "
No Peace Without Spain". At least 40 from the Tories voted to reject the treaty. In August 1712, Bolingbroke went to France and signed an armistice between Britain and France for four months. Finally, the
Treaty of Utrecht was signed in March 1713 by all the allies except the Emperor. The first production of
Joseph Addison's
Cato, a Tragedy was made by the Whigs the occasion of a great demonstration of indignation against the peace, and by Bolingbroke for presenting the actor
Barton Booth with a purse of fifty guineas for "defending the cause of liberty against a perpetual dictator". Meanwhile, the friendship between Bolingbroke and Harley, the basis of the whole Tory administration, had been gradually dissolved. In March 1711, when Marquis
Antoine de Guiscard made an attempt on Harley's life, Bolingbroke assumed temporary leadership of the ministry's affairs. His difficulty in controlling the Tory back-benchers, however, only made Harley's absence the more noticeable. In May, Harley obtained the
earldom of Oxford and became
Lord High Treasurer, while in July, St John was greatly disappointed at receiving only his viscountcy instead of the earldom lately extinct in his family, and at being passed over for the
Order of the Garter. In September 1713
Jonathan Swift came to London and made a final vain attempt to reconcile his two friends. But now a further cause of difference had arisen. The Queen's health was visibly breaking, and the Tory ministers anticipated their downfall on the accession of the
Elector of Hanover. During Bolingbroke's diplomatic mission to France he had incurred blame for remaining at the opera while the Pretender was present, and according to the
Mackintosh transcripts he had several secret interviews with him. Regular communications were kept up subsequently. In March 1714,
Charles-François d'Iberville, the French envoy in London, sent to de Torcy, the French foreign minister, the substance of two long conversations with Bolingbroke in which the latter advised patience till after the accession of
George I, when a great reaction was to be expected in favour of the Pretender. At the same time, he spoke of the treachery of Marlborough and
James FitzJames, 1st Duke of Berwick, and of one other (presumably Oxford) whom he refused to name, all of whom were in communication with Hanover. Both Oxford and Bolingbroke warned James Stuart that he could have little chance of success unless he changed his religion, but the latter's refusal does not appear to have stopped the communications. Bolingbroke gradually superseded Oxford in the leadership.
Abigail Masham, the Queen's favourite, quarrelled with Oxford and identified herself with Bolingbroke's interests. The harsh treatment of the Hanoverian demands was inspired by him, and won favour with the queen, while Oxford's influence declined; and by his support of the
Schism Bill in May 1714, an aggressive Tory measure forbidding all education by dissenters by making an episcopal licence obligatory for schoolmasters, he probably intended to compel Oxford to give up the game. Finally, a charge of corruption brought by Oxford in July against Bolingbroke and Lady Masham, in connexion with the commercial treaty with Spain, failed, and the lord treasurer was dismissed or retired on 27 July 1714. The Queen died four days later, after appointing
Charles Talbot, 1st Duke of Shrewsbury to the lord treasurership. == Exile ==
