Guy Fawkes and his men attempted to blow up the Houses of Parliament in 1605 by planting 36 barrels of gunpowder underneath. They wanted to kill King James I and cause an explosion. However, the plot failed because someone in Fawkes' group sent a letter to the King revealing the plans. Every year on November 5th in the United Kingdom, Bonfire Night is celebrated to commemorate this failed Gunpowder Plot, with bonfires, fireworks, and baked potatoes.
