In order to meet popular objections to the Constitution, the Federalists in Massachusetts drafted amendments which their Commonwealth, in ratifying the Constitution, might propose to the other States for adoption. This clever device helped win the struggle in several reluctant States. From these suggested amendments, intended to protect the individual citizen against the central government, the first 10 amendments to the Constitution, called the Bill of Rights, were formed. When the Constitution was finally ratified, the Congress arranged for the first national election and declared the new government would go into operation on March 4, 1789.

The new Federal Government first began its work in New York where Federal Hall Memorial National Historic Site is now located; then, in 1790, the Government came to Philadelphia. The move to Philadelphia resulted from a compromise known as the Residence Act, approved July 16, 1790. This act directed that the permanent capital was to be situated on the Potomac, but it also stipulated that the temporary seat of government was to be in Philadelphia for 10 years. Robert Morris was generally credited with bringing the capital to Philadelphia and was castigated by New Yorkers for his part in its removal from their city.

When the location of the capital was under consideration, the City and County of Philadelphia, as well as the Commonwealth of Pennsylvania, offered the Federal Government the use of the City Hall and the County Courthouse, two new buildings then under construction. These buildings fulfilled the original plan of a governmental center as conceived by Andrew Hamilton. The offer was accepted and for the last 10 years of the 18th century the United States Congress sat in the new County Courthouse (now known as Congress Hall), on the west side of the State House, and the U. S. Supreme Court, in the new City Hall (Supreme Court Building), on the east.

The building in which the Supreme Court sat from 1791 on was erected by the City of Philadelphia to accommodate the growth of municipal departments and functions. During the Colonial period the city government occupied the small courthouse at Second and High (now Market) Streets. When the Federal Government came to Philadelphia, the new building was not yet completed, and the Supreme Court of the United States met first in the Pennsylvania Supreme Court Chamber in the State House. After August 1, 1791, the Supreme Court generally occupied the Mayor’s Court, the large room at the south end of the first floor, in the new City Hall. It is possible that the corresponding room on the second floor was also used on occasions by the high tribunal. During its occupancy of the building, the Supreme Court was first presided over by John Jay, who was succeeded in turn as Chief Justice by John Rutledge and Oliver Ellsworth. Here the court began its active work, thereby laying the foundation for the development of the Judicial Branch of the Federal Government.

The ground on which Congress Hall stands was purchased for the Province of Pennsylvania in 1736. Although there had been plans for a long time to erect a courthouse on the lot, it was not until 1785 that the Assembly of Pennsylvania passed an act to appropriate funds for the erection of the building. Work began in 1787 and was completed in 1789. This county court building became the meeting place of the first United States Congress, Third Session, on December 6, 1790. Frederick Augustus Muhlenberg was then Speaker of the House and John Adams, President of the Senate. It is today the oldest building standing in which the Congress of the United States has met.
