Guy Fawkes and his friends planned to blow up the Houses of Parliament with 36 barrels of gunpowder underneath King James I's chair in 1605, as not all Englishmen liked the King. Their plot was discovered when the gunpowder was found, and Guy Fawkes and his co-conspirators were arrested for treason. Guy Fawkes confessed under torture and was hanged for his role in attempting to assassinate the King inside Parliament.
