"Life, Liberty and the pursuit of Happiness" is a well-known phrase from the United States Declaration of Independence. The phrase gives three examples of the unalienable rights which the Declaration says have been given to all humans by their Creator, and which governments are created to protect. Like the other principles in the Declaration of Independence, this phrase is not legally binding, but has been widely referenced and seen as an inspiration for the basis of government.

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.
