The term “United States” was termed by John Jay when he negotiated the Jay Treaty that ended the revolutionary war. John Jay insisted that King George regard the former colonies as “States”. Up to that point a “State” was a sovereign nation like France or Spain. Therefore the thirteen colonies had become thirteen thirteen sovereign states (or Nations) that united to become the Republic known (thanks to Jay) as the “United States of America”

John Jay is my great great great great great grandfather.
Very cool!
