The Gunpowder Plot Is Foiled, Giving Rise to Britain’s Bonfire Night

On November 5, 1605, the discovery of the Gunpowder Plot prevented a planned explosion at the Palace of Westminster in London. Guy Fawkes was arrested during an overnight search after gunpowder was found beneath the House of Lords. The plot’s failure would become the starting point for one of Britain’s most recognisable autumn traditions: Bonfire Night.

A Plot Discovered Before Parliament Opened

The conspirators intended to attack the State Opening of Parliament, when King James I, members of the Lords and representatives of the Commons would gather. Fawkes was one member of a group whose central organiser was Robert Catesby.

By the time of the planned ceremony, 36 barrels of gunpowder had been placed in a storeroom beneath the Lords chamber. Fawkes had been entrusted with watching over them. Although his name became the best remembered, the conspiracy involved several men and months of preparation.

The Warning That Prompted a Search

An anonymous letter warned Lord Monteagle against attending Parliament. Its author remains uncertain, but the warning reached the authorities and helped set the investigation in motion.

Searches on November 4 and during the following night uncovered the danger. Fawkes was detained around midnight, before the parliamentary gathering could take place. The gunpowder was discovered in time, and the intended explosion never happened.

From Thanksgiving to Bonfire Night

Following the plot’s failure, Parliament established November 5 as an annual day of thanksgiving. Over the centuries, the anniversary developed into a tradition associated with bonfires, fireworks and community gatherings.

Known as Bonfire Night, Firework Night or Guy Fawkes Night, the occasion preserves the memory of an event from more than four centuries ago. Behind its familiar autumn spectacle lies the story of a warning investigated and a catastrophe prevented.
