Raleigh was made governor of Jersey in 1600, but his fortunes ebbed when he drifted apart from his former ally Robert Cecil (later earl of Salisbury) in the political tempest over Essex's treason and death. He met his downfall upon the accession (1603) of James I, who had been convinced by Raleigh's enemies that Raleigh was opposed to his succession. Many of Raleigh's offices and monopolies were taken away, and, on somewhat insufficient evidence, he was found guilty of intrigues with Spain against England and of participation in a plot to kill the king and enthrone Arabella Stuart. Saved from the block by a reprieve, Raleigh settled down in the Tower and devoted himself to literature and science. There he began his incomplete History of the World.
Raleigh was released in 1616 to make another voyage to the Orinoco in search of gold, but he was warned not to molest Spanish possessions or ships on pain of his life. The expedition failed, but Laurence Kemys captured a Spanish town. Raleigh returned to England, where the Spanish ambassador demanded his punishment. Failing in an attempt to escape to France, he was executed under the original sentence of treason passed many years before.
