Gunpowder is a chemical mixture of saltpeter, sulphur, and charcoal. When ignited, it burns so rapidly that it explodes if contained to any degree. Gunpowder is believed to have been developed by the Chinese
as early as the ninth century, but it did not reach Europe
until the 1300s. The Chinese appear to have used it almost exclusively for fireworks
, but the competitive and aggressive Europeans turned it into weapon
s that revolutionized warfare.
