  The US has nine capitals before Washington dc. And they are;

1.“Philadelphia, Pa”

2.“Baltimore”

3.“Lancaster, Pa”

4.“York, Pa”.

5.“Princeton, N.J”

6.“The Maryland State House”

7.“Trenton, N.J”

8.“Federal Hall in New York City”

9.“Washington, D.C.”

Explanation:  

The United States Congress moved from “Philadelphia to Washington D.C. in 1800”. A few unique refers to fill in as the national capital during the early long periods of the United States. “In any case, in 1783, Congress chose the nation ought to have a perpetual focal point of government”. As you would expect, a few urban areas needed to have the administration, figuring the new capital would turn into a significant business and modern focus.  

In 1790, Alexander Hamilton recommended fabricating another capital ashore claimed by the national government. Congress settled on a zone along the Potomac River called the District of Columbia and asked President George Washington to pick the precise site. Washington settled on his decision the next year. It required Virginia and Maryland give some land, which they did, and the new capital was Washington.
