United States Capitol

The United States Capitol is the meeting place of the United States Congress, the legislature of the Federal government of the United States. Located in Washington, D.C., it sits atop Capitol Hill at the eastern end of the National Mall. Though not in the geographic center of the District of Columbia, the Capitol is the origin by which the quadrants of the District are divided. Officially, both the east and west sides of the Capitol are referred to as "fronts." Historically, however, only the east front of the building was intended for the arrival of visitors and dignitaries.

Prior to establishing the nation's capital in Washington, D.C., the United States Congress and its predecessors had met in Philadelphia, New York City, and a number of other locations. In September 1774, the First Continental Congress brought together delegates from the colonies in Philadelphia, followed by the Second Continental Congress, which met from May 1775 to March 1781. After adopting the Articles of Confederation, the Congress of the Confederation was formed and convened in Philadelphia from March 1781 until June 1783, when a mob of angry soldiers converged upon Independence Hall, demanding payment for their service during the American Revolutionary War. Congress requested that John Dickinson, the governor of Pennsylvania, call up the militia to defend Congress from attacks by the protesters. In what became known as the Pennsylvania Mutiny of 1783, Dickinson sympathized with the protesters and refused to remove them from Philadelphia. As a result, Congress was forced to flee to Princeton, New Jersey, on June 21, 1783, and met in Annapolis, Maryland and Trenton, New Jersey before ending up in New York, New York.

The United States Congress was established upon ratification of the United States Constitution and formally began on March 4, 1789. New York City remained home to Congress until July 1790, when the Residence Act was passed to pave the way for a permanent capital. The decision to locate the capital was contentious, but Alexander Hamilton helped broker a compromise in which the federal government would take on war debt incurred during the American Revolutionary War, in exchange for support from northern states for locating the capital along the Potomac River. As part of the legislation, Philadelphia was chosen as a temporary capital for ten years (until December 1800), until the nation's capital in Washington, D.C. would be ready. Pierre (Peter) Charles L'Enfant was given the task of creating the city plan for the new capital city. L'Enfant chose Jenkins Hill as the site for the Capitol building, with a grand boulevard connecting it with the President's House, and a public space stretching westward to the Potomac River. In reviewing L'Enfant's plan, Thomas Jefferson insisted the legislative building be called the "Capitol" rather than "Congress House". The word "Capitol" comes from Latin, meaning city on a hill and is associated with the Roman temple to Jupiter Optimus Maximus on Capitoline Hill. In addition to coming up with a city plan, L'Enfant had been tasked with designing the Capitol and President's House, however he was dismissed in February 1792 over disagreements with President George Washington and the commissioners, and there were no plans at that point for the Capitol.
