Federal Hall is a memorial and historic site at 26 Wall Street in the Financial District of Manhattan in New York City. The current Greek Revival–style building, completed in 1842 as the Custom House, is owned by the United States federal government and operated by the National Park Service as a national memorial called the Federal Hall National Memorial. The memorial is named for an earlier Federal style building on this same site, completed in 1703 as City Hall, which the government of the newly independent United States used as its capital building and called Federal Hall during the 1780s.

The Congress of the Confederation, or the Confederation Congress, formally referred to as the United States in Congress Assembled, was the governing body of the United States from March 1, 1781, until March 3, 1789, during the Confederation period. A unicameral body with legislative and executive function, it was composed of delegates appointed by the legislatures of the several states. Each state delegation had one vote. The Congress was created by the Articles of Confederation and Perpetual Union upon its ratification in 1781, formally replacing the Second Continental Congress.
