Charles I, king of England, waged a civil war (1642-9) that cost the lives of one in ten Englishmen, but in 1649 Parliament was hard put to find a lawyer with the skill and daring to prosecute the defeated King, who claimed to be above the law. The man they briefed was the radical lawyer John Cooke. His Puritan conscience, political vision, and love of civil liberties gave him the courage to bring the King's trial to its dramatic conclusion: the creation of the English Republic. Cooke would pay dearly for role in the trial. Charles I was found guilty and beheaded, but eleven years later Cooke himself was arrested, tried, and brutally executed at the hands of Charles II. Robertson, an internationally renowned human rights lawyer, provides a vivid new reading of the tumultuous Civil War years, exposing long-hidden truths: that the King was guilty as charged, that his execution was necessary to establish the sovereignty of Parliament, that the regicide trials were rigged and their victims should be seen as national heroes. John Cooke sacrificed his own life to make tyranny a crime. His trial of Charles I, the first trial of a head of state for waging war on his own people, became a forerunner of the trials of Augusto Pinochet, Slobodan Milosevic and Saddam Hussein.
