The U.S. Congress adopts the Great Seal of the United States.

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 thirteen 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.

The Great Seal is the seal of the United States. The phrase is used both for the impression device itself, which is kept by the United States secretary of state, and more generally for the impression it produces. The obverse of the Great Seal depicts the national coat of arms of the United States while the reverse features a truncated pyramid topped by an Eye of Providence. The year of the U.S. Declaration of Independence, 1776, is noted in Roman numerals at the base of the pyramid. The seal contains three Latin phrases: E Pluribus Unum, Annuit cœptis, and Novus ordo seclorum.
