1st United States Congress

The First United States Congress, consisting of the United States Senate and the United States House of Representatives, met from March 4, 1789, to March 4, 1791. This was during the first two years of George Washington's presidency. Congress met first at Federal Hall in New York City and later at Congress Hall in Philadelphia. With the initial meeting of the First Congress, the United States federal government officially began operations under the new (and current) frame of government established by the 1787 Constitution. The apportionment of seats in the House of Representatives was based on the provisions of Article I, Section 2, Clause 3 of the Constitution. Both chambers had a Pro-Administration majority. Twelve articles of amendment to the Constitution were passed by this Congress and sent to the states for ratification. The ten ratified as additions to the Constitution on December 15, 1791 are collectively known as the Bill of Rights (Amendments one through ten).
