Which 1776 document is America's 250th anniversary chiefly commemorating?

America's 250th anniversary chiefly commemorates the Declaration of Independence, adopted in 1776.

The Second Continental Congress approved the document on July 4, 1776. It announced that the thirteen American colonies regarded themselves as free and independent states rather than colonies under British rule. The document also presented political and philosophical reasons for separating from Great Britain.

Thomas Jefferson wrote the principal draft, working with a Committee of Five that included John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston. Congress revised the draft before approving it. The final text listed grievances against King George III and articulated ideas about rights and government.

A common mix-up concerns the document’s adoption, engrossing, and signing. Congress adopted the Declaration on July 4, while the famous parchment copy was signed primarily on August 2. The anniversary date follows adoption, which is why July 4, 2026, is the central America250 date.
