Which document does America250 commemorate 250 years after its adoption?

America250 commemorates the Declaration of Independence 250 years after its adoption.

The Second Continental Congress adopted the Declaration on July 4, 1776. The document announced that the thirteen American colonies regarded themselves as free and independent states rather than parts of the British Empire. Its adoption is why July 4 became the central date of the United States’ national independence observance.

Thomas Jefferson drafted the document, working with a committee that included John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston. A common mix-up is treating July 4 as the date every delegate signed the final parchment. Most delegates signed the engrossed copy on August 2, 1776, while additional signatures followed later.
