Today is Independence Day. Commonly known as the 4th of July, the day is a federal holiday in the United States that commemorates the adoption of the Declaration of Independence on July 4, 1776. That document was a statement announcing that the thirteen colonies no longer considered themselves subject to rule to the Kingdom of Great Britain. It lays out their grounds for independence, including the idea of the unalienable rights of life, liberty, and the pursuit of happiness. The holiday has traditionally been celebrated on July 4th since the inception of the Declaration of Independence. Communities across America celebrate the 4th of July with fireworks and parades.
