It was approved, after much debate (between July 1776 and November 1777), by the Second Continental Congress on November 15, 1777, and sent to the states for ratification . The Articles of Confederation came into force on March 1, 1781, after being ratified by all 13 states . A guiding principle of the Articles was to preserve the independence and sovereignty of the states . The federal government received only those powers which the colonies had recognized as belonging to king and parliament . </P> <P> The Articles formed a war - time confederation of states, with an extremely limited central government . While unratified, the document was used by the Congress to conduct business, direct the American Revolutionary War, conduct diplomacy with foreign nations, and deal with territorial issues and Native American relations . The adoption of the Articles made few perceptible changes in the federal government, because it did little more than legalize what the Continental Congress had been doing . That body was renamed the Congress of the Confederation; but Americans continued to call it the Continental Congress, since its organization remained the same . </P>
