The Mecklenburg Declaration of Independence published in 1819, was asserted to be the first declaration of independence made in the Thirteen Colonies during the American Revolution.
 It was supposedly signed on May 20, 1775, in Charlotte, North Carolina, by a committee of citizens of Mecklenburg County, who declared independence from Great Britain after hearing of the battle of Lexington.
