The Articles of Confederation, officially the Articles of Confederation and Perpetual Union, was an agreement and early body of law in the Thirteen Colonies, which served as the nation's first frame of government during the American Revolution. It was debated by the Second Continental Congress at present-day Independence Hall in Philadelphia between July 1776 and November 1777, was finalized by the Congress on November 15, 1777, and came into force on March 1, 1781, after being ratified by all 13 colonial states.
A central and guiding principle of the Articles was the establishment and preservation of the independence and sovereignty of the original 13 states. The Articles consciously established a weak confederal government, affording it only those powers the former colonies recognized as belonging to the British Crown and Parliament during the colonial era. The document provided clearly written rules for how the states' league of friendship, known as the Perpetual Union, was to be organized.
