It was there that the Continental Congress learned of the signing of the Treaty of Paris (1783) which ended the war. After the war, in the 1790s, when the United States was first founded and Washington, D.C was being built, Princeton University's Nassau Hall served as a temporary capital for the fledgling republic.
