Essex having engaged in a rash treasonable conspiracy, the object of which was to seize upon the queen's person, so as thereby to control the government, Raleigh aided in defeating his designs. But after the execution of his popular rival, Raleigh's fortune began to wane. Nevertheless, in 1600 he was made Governor of the Isle of Jersey. In the following year, in a speech made in Parliament on an act for sowing hemp, Sir Walter said: "For my part, I do not like this constraining of men to manure or use their grounds at our wills, but rather let every man use his ground to that which it is most fit for, and therein use his discretion." Queen Elizabeth died in 1603, and Raleigh's happiness ended with her life. James the First came to the throne of Great Britain prejudiced against Raleigh. He was also at this time extremely unpopular, and especially odious to the friends of the highly gifted, but rash and unfortunate Earl of Essex. In three months after the arrival of King James in England, Sir Walter was arrested on a charge of high treason, in conspiring with the Lords Cobham and Grey to place the Lady Arabella Stuart on the throne. Arraigned on charges frivolous and contradictory, tried under circumstances of insult and oppression, he was found guilty without any sufficient evidence. By their conduct on this occasion, Sir Edward Coke, Lord Chief Justice Popham, and Sir Robert Cecil proved themselves fit tools for the abject and heartless James. Raleigh, though reprieved, remained a prisoner in the Tower at the king's mercy. Lady Raleigh and her son were not excluded from the Tower, and Carew, the youngest, was born there. During his long confinement, Sir Walter devoted himself to literature and science, and enjoyed the society of a few friends, among them Hariot and the Earl of Northumberland, who was likewise a State prisoner. Sir Walter was also frequently visited by Prince Henry, the heir-apparent, who was devotedly attached to him, and who said that "none but his father would keep such a bird in a cage." Prince Charles, on the contrary, appears to have entertained a strong dislike to him. In the Tower Raleigh composed his great work, the "History of the World," the first volume of which appeared in the year 1614; it extended from the creation to the close of the Macedonian war, and embraced a period of about four thousand years. It was dedicated to Prince Henry. Raleigh intended to compose two other volumes, but owing to the untimely death of that prince, and to the suppression of it by King James, on the ground that it censured princes too freely, and perhaps to the magnitude of the task, he proceeded no further than the first volume. Oliver Cromwell recommended this work to his son.
