Fireworks were invented in China in the 1300s. They were first used in Europe in the 1500s, and in the United States in the 1600s. Fireworks became popular in the United States during the Revolutionary War, when the colonists would celebrate their victory over the British by setting off fireworks. The celebration of the Fourth of July, which commemorates the adoption of the Declaration of Independence, was also influenced by the popularity of fireworks in the United States.
