Between The signing of the DOI in 1776 and The Constitution in 1787 the American Revolution was going on [Which starts right before the DOI is signed in 1775 with the Battle of Lexington and Concord aka ‘The shot heard round the world’] and ends with the battle of Yorktown in 1781 with the victory of the American colonist under the command of general George Washington [Spoiler Alert, He becomes President Right After the Whiskey Rebellion in the 1790’s] In those 11 years many things escalated; We made a pact with the French [Which we would later diss]; Our country discovers many new faces like Alexander Hamilton, Thomas Jefferson, James Madison, John Adams, Ben Franklin, which leads to the eventual cabinetry under GW. Anyway, The colonies also started using spies as a tool in those 11 years, helping win the battles.
