National Gunpowder Day falls on November 5, the anniversary of the night in 1605 when a man was found in a cellar beneath the Palace of Westminster with 36 barrels of gunpowder and a plan to kill the king and most of England's government. Who created the observance, and whether the date was chosen for that reason, is not documented in any reliable source. The plot itself is documented exhaustively, and it is the reason November 5 means anything at all.
History
The Gunpowder Plot was a conspiracy by English Roman Catholics to blow up Parliament and King James I, together with his queen and his eldest son, on November 5, 1605. Britannica names Robert Catesby as the leader, with Thomas Winter, Thomas Percy, John Wright and Guy Fawkes as his four co-conspirators, all of them angered by James's refusal to grant more religious toleration to Catholics; they hoped the confusion after the king's murder would let English Catholics take over the country. Parliament's account has Robert Keyes and seven further known accomplices joining later.
The plot failed on a tip. An anonymous letter reached Lord Monteagle — the National Archives dates its delivery, to Monteagle's servant Thomas Ward, to October 26, 1605 — and Parliament was searched on November 4, then searched again at midnight. Sir Thomas Knyvett's men stopped a man leaving a room packed with firewood who gave his name as John Johnson; the barrels were hidden in the woodpile, and what he carried identified him as Guy Fawkes. There were 36 barrels of gunpowder in an undercroft beneath Westminster Hall. No government account gives a weight.
Fawkes was taken straight to the Tower of London. Four plotters including Catesby were killed in a shootout at Holbeach House, and by November 12 the rest had been killed or arrested. Eight survivors were tried for high treason in Westminster Hall on January 27, 1606, convicted, and hanged, drawn and quartered on January 30 and 31, Fawkes on the 31st. One detail is unsettled between two government sources: Parliament and Britannica put the intended attack on November 5, while the National Archives' teaching resource says the king was due to open Parliament on November 4.
Then Parliament made the date permanent. "An Act for a Public Thanksgiving to Almighty God every Year on the Fifth Day of November" — 3 James I, cap 1 — appointed November 5 each year as thanksgiving for "the joyful day of deliverance." Bells, bonfires, effigies and, by Parliament's count, thousands of sermons followed over two centuries. The Act remained in force until 1859.
Timeline
- October 26, 1605 — An anonymous letter warning of the plot is delivered to Lord Monteagle's servant, Thomas Ward.
- November 4-5, 1605 — Parliament is searched, then searched again at midnight. Guy Fawkes is found with 36 barrels of gunpowder in an undercroft beneath Westminster Hall, gives his name as John Johnson, and is arrested and taken to the Tower of London.
- November 12, 1605 — By this date every co-conspirator has been killed or arrested. Four, including the ringleader Robert Catesby, died in a shootout at Holbeach House.
- January 1606 — Parliament passes the Thanksgiving Act, appointing November 5 an annual day of public thanksgiving. The Parliamentary Archives catalogue the Act under the 1605 session.
- January 27-31, 1606 — Eight surviving plotters are tried in Westminster Hall and convicted of high treason. The executions take place on January 30 and 31; Fawkes is executed on the 31st.
- November 1606 — The first Gunpowder Treason Day is observed. Annual services continue under the Act until it ceases to be in force in 1859.
How to observe
Read the documents instead of the story. The National Archives' Gunpowder Plot teaching resource reproduces the primary papers, including the royal proclamation of November 5, 1605, which describes only "a great quantity of Powder ... conveyed into a vault under the said Chamber" and gives no barrel count at all. The original Thanksgiving Act is held by the Parliamentary Archives under HL/PO/PU/1/1605/3J1n1.
The lantern Fawkes is said to have carried that night is in the Ashmolean Museum in Oxford. The cellar is not: it was destroyed in the fire of 1834.
And if a State Opening is coming up, watch for the search. The Yeomen of the Guard still go through the cellars beforehand — normally in November, as State Openings have been since 1928 — and Parliament describes the ritual without ceremony as "a picturesque custom rather than a serious anti-terrorist precaution."
Frequently asked questions
Is National Gunpowder Day the same thing as Guy Fawkes Night?
No. Guy Fawkes Night, or Bonfire Night, is the documented British observance of November 5; Parliament traces it back to the first Gunpowder Treason Day in November 1606. "National Gunpowder Day" has no founder, organization or founding year traceable to a reliable source.
Was Guy Fawkes the leader of the Gunpowder Plot?
No. Britannica and Parliament both name Robert Catesby. Parliament calls Fawkes "a minor cog in the wheel" who is "remembered wrongly as the principal conspirator." He was the one guarding the powder, which is why he was the one caught.
How much gunpowder was under Parliament?
Thirty-six barrels, hidden in a woodpile in an undercroft beneath Westminster Hall, according to the National Archives. No government account gives a weight, and the royal proclamation of November 5, 1605 says only "a great quantity of Powder."
Was November 5 ever a legally required observance?
Yes. An Act of Parliament, 3 James I cap 1, appointed it an annual day of public thanksgiving, and for about two centuries special church services were held under its provisions. Parliament records that the Act remained in force until 1859.
