What is US Declaration of Independence?

The Declaration of Independence was a statement adopted by the continental Congress on July 4, 1776 which announce that the 13 American Colonies, then at war with Great Britain regarded themselves as independent states and no longer a part of the British Empire. It contained that all men are created equal that they are endowed by their Creator with certain unalienable Rights, that among these are Liberty and the pursuit of Happiness. This view was notably promoted by Abraham Lincoln, who considered the Declaration to be the foundation of his political philosophy and argued that the Declaration is a statement of principles through which the United States Constitution should be interpreted. It has worked for the rights of marginalized people throughout the world.
