The President's House, Philadelphia, PA
July 4, 1791
President George Washington yawned widely, and stepped to the window of his bedroom, looking out on the city below. He smiled at the sight of a few waving American flags hanging from the sides of buildings, there in celebration and recognition of the nation's declaration of independence from Great Britain just fifteen years ago. He leaned against the wall and took in the scene below, men bustling about in their carriages and atop horseback, the scent of salty sea air filling his nostrils...
Wait.
What?
"Mister President!" exclaimed a voice, causing Washington to spin around, startled. Christopher Sheels bowed low, and said, "Sir, there is something you must see."
Washington got dressed as swiftly as one of his advanced age could, and left his room, his slave following closely behind. They walked a few blocks back to the State House and Sheels directed his master to climb to the top of the bell tower.
"Oh my... We surely do have a problem on our hands..."
George Washington surveyed the horizon. Where the Delaware River had cut off Pennsylvania from New Jersey was now open ocean as far as the eye could see.

On the night of July 3/4, 1791, ten US cities were hurtled through time and space to a virgin Earth. In a twist of fate, whatever force that had sent these cities across the globe transported them to the eastern Mediterranean, on the coasts of Greece and Asia Minor. The cradle of democracy.
The cities were sent to the sites of OTL great Ancient Greek cities, these being:
Philadelphia/Athens
New York City/Corinth
Boston/Sparta
Baltimore/Thebes
Charleston/Syracuse
Providence/Argos
Salem/Miletus
Jamestown/Alexandria
Williamsburg/Ephesus
Newport/Byzantion
While the United States spread its tendrils across Europe after a period of instability, some within its borders did not like this, and fled. Old British Loyalists who had not yet left for Canada made their way across the sea to the site of Carthage, founding New London and the United Kingdom of New Britain. In the early 1800s, during the presidency of Alexander Hamilton, rival Aaron Burr attempted to persuade the state of Carolina (formed from Charleston) to secede from the union, to no avail. To escape the treasonous charges levied on his head, he fled down the Persian Gulf to the Strait of Hormuz, forming his own sovereign (but downtrodden) country.
