King was born in Norwich some time in 1735, and died 16 April 1807 at Beckenham, Kent. He attended Clare Hall, Cambridge in 1757, and in 1758 was admitted to Lincoln's Inn; he was called to the bar in 1763. Although wealthy thanks to a bequest from an uncle, King nevertheless practised law, attending the Norfolk circuit and serving as recorder for King's Lynn. His first published work, An Essay on the English Constitution and Government, appeared in 1767, but it was not until his retirement in the 1790s that King began to write More prolifically. He produced a notable antiquarian work, the four-volume Munimenta Antiqua, or, Observations on Ancient Castles, and several works perhaps best described as amateur theology, including Hymns to the Supreme Being (1795), Remarks on the Signs of the Times (1799) and Morsels of Criticism (1800).
