Bonfire Night, also known as Guy Fawkes Night, is celebrated on November 5th in the UK to commemorate the failure of the Gunpowder Plot of 1605. The plot was a conspiracy by a group of English Catholics, including Guy Fawkes, to blow up the Houses of Parliament and assassinate King James I in protest against the oppression of Catholics. When the plot was foiled and Guy Fawkes was arrested, Londoners lit bonfires to celebrate the King's survival and to demonstrate the consequences of treason. This event has since evolved into an annual tradition involving bonfires, fireworks, and community gatherings, serving as a historical remembrance and a festive social occasion.
