The 4th of July has been an important holiday but today, more and more people do not know why we actually celebrate this day. If you are not up to date on your history of the United States, July 4th, 1776 is the day that the colonies decided to declare themselves independent of Britain. By writing a very detailed decree, they decided that they no longer would need to be governed by the Kings of England that had been so very unjust to the colonists in the years before. On July 4th, America was born. We call the 4th of July Independence Day because this day was the day they declared independence from Great Britain.
