'In 1775, people in New England began fighting the British for their independence. On July 2, 1776, the Congress secretly voted for independence from Great Britain. The Declaration of Independence was first published two days later on July 4, 1776. The first public reading of the Declaration of Independence was on July 8, 1776. Delegates began to sign the Declaration of Independence on August 2, 1776.
The first description of how Independence Day would be celebrated was in a letter from John Adams to his wife Abigail on July 3, 1776. He described "pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations" throughout the United States. However, the term "Independence Day" was not used until 1791.
Interestingly, Thomas Jefferson and John Adams, both signers of the Declaration of Independence and presidents of the United States, died on July 4, 1826 - exactly 50 years after the adoption of the declaration.'
