America celebrates July 4 as Independence Day because it was on July 4, 1776, that members of the Second Continental Congress, meeting in Philadelphia, adopted the final draft of the Declaration of Independence.
Following its adoption, the Declaration was read to the public in various American cities. Whenever they heard it, patriots erupted in cheers and celebrations.
In 1777, Philadelphians remembered the 4th of July. Bells were rung, guns fired, candles lighted, and firecrackers set off. However, while the War of Independence dragged on, July 4 celebrations were modest at best.
When the war ended in 1783, July 4 became a holiday in some places. In Boston, it replaced the date of the Boston Massacre, March 5, as the major patriotic holiday. Speeches, military events, parades, and fireworks marked the day. In 1941, Congress declared July 4 a federal holiday.
Over time, various other summertime activities also came to be associated with the Fourth of July, including historical pageants, picnics, baseball games, watermelon-eating contests, and trips to the beach. Common foods include hot dogs, hamburgers, corn on the cob, apple pie, cole slaw, and sometimes clam bakes.
