Independence Day The Fourth of July marks the anniversary of America's Declaration of Independence from Britain. During the summer of 1776, most American colonists were increasingly angry about what they considered unfair treatment by the British government. By June, fighting had already taken place between colonial forces and Britain. The idea of independence was spreading. Delegates from the thirteen colonies gathered. The Continental Congress decided that a document declaring separation from Britain should be declared. On July fourth, the Continental Congress voted to approve the Declaration of Independence. It says that people have the right to change their government if it denies them their rights. It states that everyone has the right to life, liberty and the pursuit of happiness.
