In 1783 Congress decided to create a new capital apart from any state, and in 1787 the framers of the Constitution provided for a capital district. The U.S. capital was originally Philadelphia. Washington D.C. became the new capital on July 16, 1790.
Washington, D.C. is the capital city of the United States. It is not a state or in a state. The President of the United States and many major national government offices are in the city. Thus, it is the political center of the United States. Washington was named after the first U.S. President, George Washington. The D.C. stands for District of Columbia, a special area created that is not a state. At first, it was made up of a piece from Virginia south of the Potomac River and a piece from Maryland north of the Potomac River.
