Which document is America250 primarily commemorating 250 years after its creation?

America250 primarily commemorates 250 years since the Declaration of Independence was adopted in 1776.

The Declaration announced that the thirteen American colonies regarded themselves as independent states rather than colonies governed by Great Britain. It presented a political explanation for separation and included the famous statement that people possess unalienable rights, including life, liberty, and the pursuit of happiness.

The Second Continental Congress adopted the resolution for independence on July 2, 1776, and approved the wording of the Declaration on July 4. The document was then distributed and publicly read, while most delegates signed the engrossed parchment later.

The Constitution is a different founding document, created in 1787 and ratified in 1788. The Articles of Confederation served as the first national governing framework before the Constitution replaced it.
