Which document does America's 250th anniversary commemorate most directly?

America's 250th anniversary most directly commemorates the United States Declaration of Independence.

The Second Continental Congress adopted the Declaration on July 4, 1776, announcing that the Thirteen Colonies were free and independent states rather than part of the British Empire. America250 and the United States Semiquincentennial therefore focus on the document’s adoption as the anniversary’s defining event.

The Declaration explained the colonies’ grievances against King George III and stated principles concerning natural rights and government. Thomas Jefferson drafted the initial text as part of a five-member committee, although Congress revised the wording during debate.

The Constitution is a neighboring but different founding document: it established the federal government in 1787 and took effect in 1789. The Articles of Confederation preceded it as the first national governing framework. The anniversary’s core date is tied to independence, not the Constitution’s ratification.
