John Trenchard
Sir John Trenchard (30 March 1640 - 27 April 1695), English politician and Commonwealthman, belonged to an old Dorset family, his father being Thomas Trenchard (1615-1671), of Wolverton, and his grandfather Sir Thomas Trenchard (1582-1657), also of Wolverton, who was knighted by James I in 1613.Born at Lytchett Matravers, near Poole, and educated at New College, Oxford, John Trenchard entered parliament as member for Taunton in 1679, and associated himself with those who proposed to exclude the Duke of York from the throne. He attended some of the meetings held by these malcontents and was possibly concerned in the Rye House Plot; at all events he was arrested in July 1683, but no definite evidence was brought against him and he was released. When Monmouth landed in the west of England in June 1685 Trenchard fled from England, but was pardoned through the good offices of William Penn and returned home two years later. Again he entered parliament, but he took no active part in the Revolution of 1688, although he managed to secure the good will of William III. He was knighted by the king and made chief justice of Chester, and in 1692 he was appointed Secretary of State. He and the government incurred much ridicule through their failure to prove the existence of a great Jacobite plot in Lancashire and Cheshire in which they had been led to believe.
From 1720 to 1723, Trenchard, along with Thomas Gordon, wrote a series of 144 essays entitled Cato's Letters, condemning corruption and lack of morality within the British political system and warning against tyranny. The essays were published as Essays on Liberty, Civil and Religious, first in the London Journal and then in the British Journal. These essays became a cornerstone of the Commonwealthmen tradition.
Sir John died on 27 April 1695. His wife was Philippa (d. 1743), daughter of George Speke (d. 1690) of White Lackington, Somerset.
