Sir Edward Coke SL was an English barrister, judge, and politician who is considered to be the greatest jurist of the Elizabethan and Jacobean eras.
Born into an upper-class family, Coke was educated at Trinity College, Cambridge, before leaving to study at the Inner Temple, where he was called to the Bar on 20 April 1578. As a barrister he took part in several notable cases, including Slade's Case, before earning enough political favour to be elected to Parliament, where he served first as Solicitor General and then as Speaker of the House of Commons. Following a promotion to Attorney General he led the prosecution in several notable cases, including those against Robert Devereux, Sir Walter Raleigh, and the Gunpowder Plot conspirators. As a reward for his services he was first knighted and then made Chief Justice of the Common Pleas.
As Chief Justice, Coke restricted the use of the ex officio oath and, in the Case of Proclamations and Dr. Bonham's Case, declared the King to be subject to the law, and the laws of Parliament to be void if in violation of "common right and reason".
