The document often referred to as the foundation of American democracy is the Declaration of Independence, adopted on July 4, 1776. Drafted primarily by Thomas Jefferson, the Declaration outlined the colonies' grievances against British rule and asserted their right to self-governance. It emphasized principles such as individual liberty, equality, and the pursuit of happiness. The Declaration of Independence was pivotal in rallying colonists and securing international support during the American Revolutionary War. Its ideals have since influenced various democratic movements around the world, echoing the belief that governments derive their just powers from the consent of the governed.
