Fourth of July Fireworks
The first fireworks were used as early as 200 BC. The tradition of setting off fireworks on the 4 of July began in Philadelphia on July 4, 1777, during the first organized celebration of Independence Day. Ship’s cannon fired a 13-gun salute in honor of the 13 colonies. The Pennsylvania Evening Post reported: “at night there was a grand exhibition of fireworks (which began and concluded with thirteen rockets) on the Commons, and the city was beautifully illuminated.” That same night, the Sons of Liberty set off fireworks over Boston Common.
