Guy Fawkes Night, also known as Bonfire Night or Firework Night, is an annual celebration held on 5th November in Great Britain. It commemorates the events from 5th November 1605, when a member of the Gunpowder Plot, Guy Fawkes, was arrested after being caught guarding 36 barrels of gunpowder that had been placed by the plotters under the House of Lords.
The Gunpowder Plot was a planned assassination of the Protestant King, King James I, by a group of provincial English Catholics led by a man named Robert Catesby. They planned to blow up the House of Lords during the State Opening of Parliament. The conspirators were caught and at their trial on the 27th January 1606 they were convicted and sentenced to be hung, drawn and quartered.
To celebrate the fact the King had survived the attempt on his life, bonfires were lit around London. Months later the Observance of 5th November Act was introduced, it enforced an annual public day of thanksgiving for the plot‘s failure.
Today Bonfire Night is dedicated to bonfires, fireworks and celebrations, and is usually celebrated at large organised events.
So:
Remember, remember, the 5th of November The Gunpowder Treason and plot;
I see of no reason why Gunpowder Treason Should ever be forgot.
