his life. While imprisoned in the Tower, Raleigh wrote his incomplete The Historie of the World. Using a wide array of sources in six languages, Raleigh was fully abreast of the latest continental scholarship. He wrote not about England, but of the ancient world with a heavy emphasis on geography. Despite his intention of providing current advice to the King of England, King James I complained that it was "too sawcie in censuring Princes". Raleigh remained imprisoned in the Tower until 1616.

According to biographers, Raleigh's last words, spoken to the hesitating executioner, were: "What dost thou fear? Strike, man, strike!" Thomas Hariot may have introduced him to tobacco. Having been one of the people to popularise tobacco smoking in England, he left a small tobacco pouch, found in his cell shortly after his
