OhioSTATE13 July 1787
(Territory)
Organized as "The Territory Northwest of the River Ohio" (informally, the "Northwest Territory")-- the first U.S. Territory and the only Territory formally authorized by the Congress which operated under the Articles of Confederation. An Act of Congress of 7 August 1789 (1 Stat. 50) brought the governance of this Territory into fullest compliance with the new Constitution of the United States.
[NOTE: Virginia was the last of the States with land claims in this area to agree to cede said claims (it was this that allowed Maryland, which had objected to all such claims, to become the 13th and final State to ratify the Articles of Confederation, 1 March 1781); the Confederation Congress formally accepted Virginia's terms re: said cession (that the lands be ceded to the UNITED STATES OF AMERICA as an entity in and of itself) on 1 March 1784: technically, then, this is the actual date upon which the lands northwest of the Ohio River first became the very first "U.S. Territory"]
