King was born at Ockham, Surrey on 31 August 1776, the eldest son of Peter, 6th Baron King of Ockham. He died, probably of stomach cancer, at Ockham on 4 June 1833. He was educated at Eton and then at Trinity College, Cambridge, leaving without taking a degree. He succeeded his father as seventh Baron King of Ockham in 1793. After touring the continent, he took up his seat in the House of Lords upon attaining his majority. Here he became close to Lord Holland, and generally supported the Whig cause; he opposed the suspension of habeus corpus and the suspension of payments in coin by the Bank of England. In the 1820s he was a vigorous opponent of the Corn Laws. His speeches in the Lords and many of his letters are reproduced in Fortescue (1844).
