This 1792 map was among the first printed plans of Washington, D.C., the new seat of government for the federal government. Its location on the Potomac River was determined as a result of the Compromise of 1790. Thomas Jefferson and his supporters agreed that the nation would take on state debts incurred during the Revolutionary War in exchange for the mid-Atlantic capital site selected by George Washington. Though Maryland surveyor Andrew Ellicott created this map, he based it on designs by French engineer Pierre L'Enfant.
