Quick Summary

Fire, the rapid burning of combustible material with heat and flame, has been a crucial tool for humanity since early hominids first controlled it, possibly as early as 1.4 million years ago. Initially used for warmth, cooking, and hunting, fire also played a role in warfare and land management. The ability to manufacture fire, through methods like friction drills or striking flint against pyrite, was a significant advancement.1

In warfare, flammable substances known as incendiaries have been used since antiquity. True Greek fire, a petroleum-based mixture invented in the 7th century CE, was particularly effective at sea and could not be extinguished with water. Modern warfare utilizes incendiary bombs, which contain agents like jellied gasoline designed to start fires at their targets. An incendiary can also refer to a person who incites conflict or commits arson.234
