Which founding document is the central subject of America’s 250th-anniversary celebration?

The Declaration of Independence is the founding document at the center of America’s 250th-anniversary celebration.

The Second Continental Congress adopted the document on July 4, 1776, announcing that the thirteen American colonies regarded themselves as independent states no longer subject to British rule. Its adoption is the historical event commemorated by the 2026 America250 observance.

The Declaration combines a philosophical statement about natural rights with a detailed list of grievances against King George III. Its best-known principles include equality and the idea that governments derive their authority from the consent of the governed.

The Declaration is distinct from the Constitution, which was drafted in 1787 and established the framework of the United States federal government. It is also distinct from the Articles of Confederation, the first national governing framework adopted during the Revolutionary War. These documents are related, but they represent different stages of American political history.
