The Continental Congress was a series of legislative bodies, with some executive function, who acted as the Provisional Government for the Thirteen Colonies of Great Britain in North America, and the newly declared United States before, during, and after the American Revolutionary War. The Continental Congress refers to both the First and Second Congresses of 1774–1781 and at the time, also described the Congress of the Confederation of 1781–1789. The Confederation Congress operated as the first federal government until being replaced following ratification of the U.S. Constitution. Until 1785, the Congress met predominantly at what is today Independence Hall in Philadelphia, though it was relocated temporarily on several occasions during the Revolutionary War and the fall of Philadelphia.
