The document adopted in 1776 that articulated the principles of individual freedom is the Declaration of Independence. Drafted primarily by Thomas Jefferson, the Declaration announced the thirteen American colonies' separation from British rule. It outlined fundamental ideals such as the rights to life, liberty, and the pursuit of happiness, reflecting Enlightenment principles. The document emphasized that governments derive their just powers from the consent of the governed, and it articulated the philosophical foundation for democratic governance. The Declaration of Independence remains a symbol of American values and has inspired numerous movements for liberty worldwide.
