Washington, D.C. A new federal city was then constructed on the north bank of the Potomac, to the east of Georgetown. On September 9, 1791, the three commissioners overseeing the capital's construction named the city in honor of President Washington. The federal district was named Columbia, which was a poetic name for the United States commonly in use at that time.[20][21] Congress held its first session in Washington on November 17, 1800.[22]
