jul 4, 1776 - The Declaration of Independence
On July 4, 1776, the Second Continental Congress adopted the Declaration of Independence which formally proclaimed the 13 colonies as independent. The war, however, continued as Britain was not willing to give up its North American colonies. The original Declaration of Independence - mainly drafted by the future US President Thomas Jefferson - is today permanently exhibited in the Rotunda for the Charters of Freedom in the National Archives building in Washington, D.C.
