In 1776, the Colonies of the United States were changing. The constant battle between the U.S. and Britain had come to a head. The Colonies were tired of being under British control, and were ready to become a nation of their own. The leaders of the revolution agreed that a declaration of independence was to be written.
For several months, dating from April-July of 1776, several different copies of the Declaration were brought forth. The were then voted on by the Constitutional Congress, a group of intellectuals from each of the thirteen colonies.
Finally, on July 4, 1776, the final copy of the Declaration was voted on and signed into law by all members of the Constitutional Congress. The United States was to be a free nation.
