History of gunpowder
Gunpowder history traces the invention of black powder in China, its spread across Eurasia, and its changing roles in warfare and society.
Chinese alchemy: A tradition of Chinese practices that pursued medicines, longevity, and transformations of matter. Alchemical experiments with sulfur and saltpeter preceded the earliest gunpowder recipes.
Black powder: A low explosive mixture of potassium nitrate, charcoal, and sulfur. This was the principal gunpowder formulation behind the historical weapons and uses traced here.
Siege of Constantinople (1453): The Ottoman conquest of Constantinople, aided by large artillery, in 1453. The siege illustrates the battlefield impact of massive gunpowder cannon.
Smokeless powder: A propellant based mainly on nitrated organic compounds that produces far less smoke than black powder. Its late-19th-century adoption displaced black powder in most firearms and artillery.
Wujing Zongyao: An 11th-century Chinese military compendium containing early written gunpowder formulas. Its recipes document gunpowder’s military use in China by 1044.
Hand cannon: A small, early firearm in which gunpowder propelled a projectile from a metal barrel. Hand cannons mark the transition from incendiary gunpowder weapons to firearms.
Ottoman Empire: An empire founded in Anatolia that ruled parts of southeastern Europe, western Asia, and North Africa. Ottoman rulers adopted and expanded artillery, making gunpowder weapons instruments of imperial power.
Nitrocellulose: A highly combustible material made by nitrating cellulose, used in explosives and smokeless propellants. It became a key ingredient in the propellants that superseded traditional gunpowder.
Fire lance: An early firearm consisting of a spear or tube that projected flame and, later, projectiles. It shows how Chinese forces first applied gunpowder to handheld weapons.
Bombard (weapon): A large medieval cannon used to fire stone or metal projectiles. Bombards brought gunpowder artillery to sieges and the destruction of fortified walls.
