Which document is the central subject of the United States’ 250th anniversary in 2026?

The Declaration of Independence is the central document of the United States’ 250th anniversary in 2026.

The Declaration was adopted by the Second Continental Congress on July 4, 1776. It announced that the thirteen American colonies regarded themselves as free and independent states rather than colonies subject to British rule.

America250 therefore centers on the 250th anniversary of the Declaration’s adoption and the independence movement surrounding it. The document is not a constitution: it explains the political case for separation, while the U.S. Constitution later established the structure of the federal government.

The Declaration’s best-known opening principles discuss equality, rights, and government deriving its powers from the consent of the governed. Its historical importance extends beyond the date itself, influencing later American political arguments and commemorations.
