A state legislature in the United States is the legislative body of any of the 50 U.S. states. The formal name varies from state to state. In 27 states, the legislature is simply called the Legislature or the State Legislature, while in 19 states the legislature is called the General Assembly. In Massachusetts and New Hampshire, the legislature is called the General Court, while North Dakota and Oregon designate the legislature the Legislative Assembly.

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 of America from March 1, 1781, to March 4, 1789. 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. It was preceded by the Second Continental Congress (1775–1781) and was created by the Articles of Confederation and Perpetual Union in 1781.

The Congress continued to refer itself as the Continental Congress throughout its eight-year history, although modern historians separate it from the two earlier congresses, which operated under slightly different rules and procedures until the later part of American Revolutionary War. The membership of the Second Continental Congress automatically carried over to the Congress of the Confederation when the latter was created by the ratification of the Articles of Confederation, and had the same secretary as the Second Continental Congress, Charles Thomson.

The Congress of the Confederation was succeeded by the Congress of the United States as provided for in the new United States Constitution, proposed September 17, 1787, in Philadelphia and adopted by the United States in 1788.
