 Guy Fox Day, also called Bonfire Night, is celebrated on November the 5th in the UK. It commemorates the failure of the so-called Gunpowder Plot of 1605. Let's see how the failed plot to blow up England's houses of parliament sparked Guy Fox Day. Zelos, Roman Catholics were enraged at King James I for refusing to grant greater religious tolerance to Catholics. They planned to blow up the houses of parliament during the state opening of parliament in the hope that Catholic rule could be re-established in England. However, the plan failed as it was revealed to the authorities in an anonymous letter. One of the conspirators, Guy Fox, was discovered guarding 36 barrels of gunpowder during a search of the House of Lords in the evening on 4 November 1605. Guy Fox was taken into custody. He and the other conspirators were tried, convicted and executed. In the aftermath, parliament declared November the 5th the National Day of Thanksgiving. The first celebration of it took place in 1606. Today, Guy Fox Day is still celebrated in the United Kingdom. It is also celebrated in a number of countries that were formerly part of the British Empire. Guy Fox Day is celebrated with parades, fireworks, bonfires and food. The fireworks represent the explosives that were never used by the plotters. In addition, guards perform an annual search of the parliament building to check for potential arsonists, although it is more ceremonial than serious. Straw, effigies of Guy Fox are tossed on a bonfire and children often recite rhymes associated with the occasion. The best known of these rhymes dates from the 18th century and goes like this. Remember, remember, the 5th of November. Gunpowder, treason, and plot. We see no reason why gunpowder treason should ever be forgot. And so, the failure of the gunpowder plot of 1605 has indeed not been forgotten and is again celebrated this year on November the 5th.
