The surrender of Cornwallis terminated the struggle. The peace treaty
was signed in 1783. The financial situation was very deplorable. One of
the greatest difficulties that confronted the colonists, was the limited
power of Congress. The states could regulate commerce and exercise
nearly all authority. But disputes regarding their boundaries prevented
their development as a united nation.

Congress issued an ordinance in 1784 under which territories might
organise governments, send delegates to Congress, and obtain admission
as states. This was made use of in 1787 by the Northwest Territory, the
region lying between the Ohio and the Mississippi and the Great Lakes.
The states made a compact in which it was agreed that there should be no
slavery in this territory.

The critical period lasted until 1789. In the absence of strong
authority, economic and political troubles arose. Finally, a commission
appointed by Maryland and Virginia to settle questions relating to
navigation on the Potomac resulted in a convention to adjust the
navigation and commerce of the whole of the United States, called the
Annapolis Convention from the place where it met, May 1, 1787. Rhode
Island was the only state that failed to send delegates. Instead of
taking up the interstate commerce questions the convention formulated
the present Constitution. A President, with power to carry out the will
of the people, was provided, and also, a Supreme Court.
