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 Congress continued to refer to itself as the Continental Congress throughout its eight-year history. Modern historians, however, separate it from the two earlier congresses, which operated under slightly different rules and procedures until the end of the Revolutionary War. Membership of the Second Continental Congress automatically carried over to the Congress of the Confederation, and Charles Thomson, secretary of the Second Continental Congress, continued in that capacity in the Congress of the Confederation.
