On 6 January 1681 Child was returned after a contest as a representative for St. Dunstan's precinct of the ward of
Farringdon Without in the court of common council, one of his opponents being Mr. Taylor of the Devil tavern. It is stated in the 'London Gazette' of 3 December 1683 that the subscriptions towards the lottery of the late Prince Rupert's jewels, valued at £20,000, were paid in to Mr. Child at
Temple Bar. The king himself is said to have taken a great interest in the matter, and personally counted the tickets at Whitehall. It is also stated that Child was appointed by the Bishop of London to receive the collection made in February 1682 for the restoration of St. Albans Aabhey. In October 1689, Child was elected alderman of the ward of Farringdon Without, and on the 29th of the same month he was knighted by William III at Guildhall at the mayoralty banquet. Child was a
whig, and now acted as one of the leaders of that party in the corporation. He was admitted a member of the
Hon. Artillery Company in February 1690. In 1690 the elections of mayor, sheriffs, and chamberlain were contested on strictly political grounds, the church party putting forward Sir W. Hedges and Thomas Cook for the shrievalty, who were opposed by Child and
Sir Edward Clarke on behalf of the whigs. Child headed the poll by a narrow majority. In March 1694 he was elected by the court of lieutenancy to be one of the six colonels of the city trained bands. Child stood for Parliament at
Devizes at the 1695 general election, but was defeated. He was returned unopposed as
Member of Parliament for Devizes at the 1698 general election On 29 September 1698 he was elected lord mayor of London for the following year. His inauguration took place on 29 October, and the pageant, prepared for the occasion by
Elkanah Settle at the expense of the Company of Goldsmiths, was published in folio, with plates, under the title ''Glory's Resurrection, be° the Triumphs of London revived, for the inauguration of the Right Honourable Sir Francis Child, Kt., Lord Mayor of the City of London, 1698
. This pageant is now very scarce; a copy is preserved in the Guildhall Library. The procession is described in the London Gazette,'' and appears to have been of more than usual grandeur. The ambassadors who were in town went into the city to see the sight, and on the return from Westminster the civic barges stopped at Dorset Stairs, where the lord mayor and aldermen disembarked and were entertained by the Earl of Dorset. The procession afterwards landing at Blackfriars proceeded to Guildhall, accompanied by the lords justices, who were attended by the life guards and the horse grenadiers. Child is said by Luttrell (iv. 577) to have been 4,000l. out of pocket by the expenses of his year of office. The emoluments of the mayoralty at that time chiefly consisted of the money realised by the sale of such city offices as fell vacant during the year. During his mayoralty he took measures to regulate the price of corn, and appointed officers to attend daily at Queenhithe and post up the prices to prevent imposition upon the public. Child held the post of jeweller to the king, which he resigned in 1697, his successor being Sir Stephen Evans. Child's vast wealth enabled him to lend the government large sums of money. In August 1692, he joined Sir J. Herne and Sir S. Evans in an advance of £50,000 to the crown to meet the expenses of the government of Ireland. The forthcoming election of members of parliament for the
City of London gave rise to an exciting struggle in December 1700. Child, who was now a member of the Tory party, stood unsuccessfully for London at the 1st general election of 1701, when the four Whig candidates carried the seats. However he was returned again at Devizes at that election and at the second general election in 1701. At the 1702 general election, Child was returned for both Devizes and the City of London, and chose to sit for London. He was master of the Goldsmiths' Company in 1702 At the 1705 general election Child decided not to stand for the City of London and was returned again for Devizes. Then at the
1708 general election he decided not to stand at Devizes, but was defeated at the City of London and left without a parliamentary seat. At the
1710 general election he stood at Devizes with Serjeant Webb but was caught up in a double return and was not seated until 16 December. He appears from the state papers to have been connected in 1711 with the receipt of the land tax for Wiltshire. == Later life and death ==
