The alchemists who were trying to live forever
The inventors were not weapon-makers. Taoist alchemists of the Tang dynasty spent their working lives chasing the elixir of life, heating and blending minerals in search of a preparation that would let an emperor live forever. Somewhere around the middle of the ninth century, one of those blends caught fire in a way nobody expected. A Taoist text from about 850 AD warns fellow practitioners about it directly: monks had scorched their hands and faces, and the building where they worked burnt to the ground.
The warning stopped nobody. Word spread.
The first written record
The earliest surviving practical description of gunpowder sits in the Wujing Zongyao, a military compendium compiled in 1044 for the Song court. By then the accident had become an industry, and Song armies fielded fire arrows and early bombs against the Mongols in the centuries that followed. It didn't save them. Mongol armies carried the knowledge west as they conquered, and after roughly four hundred years the secret finally left China.
How gunpowder reached Europe
Knowledge travelled along the Silk Road through the Islamic world, where early scholars called saltpetre "Chinese snow". The first European to describe gunpowder in writing was the English friar Roger Bacon, around 1267. Germany tells of the monk Berthold Schwarz discovering it independently a century later; historians treat him as legend. What is certain is that English armies had early cannon at Crécy by 1346, and by 1605 the substance was infamous enough in Britain that Guy Fawkes could stack thirty-six barrels of it under the House of Lords. That story has its own page.
From weapon to fireworks
Celebration came before warfare, oddly. The Chinese had been throwing bamboo stems on fires for centuries before gunpowder existed, because the trapped air pops loudly and the bangs were held to scare off evil spirits. Packing the new powder into bamboo was the natural next step, and by the Song dynasty fireworks belonged to festivals and state occasions. Italy took the craft up in the Renaissance and gave shells their colour and shape; the modern display is a Song festival refined by Italian hands. The longer story runs in our guide to when fireworks were invented.
Black powder is still doing its original job today. It lifts every shell and bursts every cake we sell, more than a thousand years after a Tang alchemist failed to live forever. If that puts you in the mood, the Bonfire Night buying guide is the place to start.
Frequently asked questions
Who invented gunpowder?
Chinese alchemists of the Tang dynasty, in the ninth century AD. No single inventor is recorded; it emerged from experiments seeking an elixir of immortality.
When was gunpowder invented?
Around 850 AD, with the earliest surviving military description written down in 1044 in the Wujing Zongyao.
Did Europeans invent gunpowder independently?
No. It reached Europe from China via the Silk Road and the Mongol conquests. Roger Bacon described it around 1267, and the German monk Berthold Schwarz is legend rather than history.
Is gunpowder still used in fireworks?
Yes. Traditional black powder still lifts shells into the sky and ignites the effects in modern consumer fireworks.
