The quotation "all men are created equal" is found in the United States Declaration of Independence. The final form of the sentence was stylized by Benjamin Franklin, and penned by Thomas Jefferson during the beginning of the Revolutionary War in 1776. It reads:"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

The Declaration of Independence, formally titled The unanimous Declaration of the thirteen united States of America, is the founding document of the United States. On July 4, 1776, it was adopted unanimously by the 56 delegates to the Second Continental Congress, who had convened at the Pennsylvania State House, later renamed Independence Hall, in the colonial era capital of Philadelphia. The declaration explains to the world why the Thirteen Colonies regarded themselves as independent sovereign states no longer subject to British colonial rule.
