On July 4th 1776 the United States Declaration of Independence was adopted by the Second Continental Congress. It was adopted at Philadelphia, Pennsylvania on July 4, 1776, which announced that the thirteen American colonies, then at war with the Kingdom of Great Britain, regarded themselves as thirteen newly independent sovereign states, and no longer under British rule. Instead they formed a new nation – the United States of America.
The 4th of July is now celebrated annually in the United States as Independence Day, essentially the United States birthday. Independence Day is commonly associated with fireworks, parades, barbecues, carnivals, fairs, picnics, concerts, baseball games, family reunions, and political speeches and ceremonies, in addition to various other public and private events celebrating the history, government, and traditions of the United States. Independence Day is the National Day of the United States.
