<P> The Articles of Confederation, formally the Articles of Confederation and Perpetual Union, was an agreement among the 13 original states of the United States of America that served as its first constitution . 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 central government established by the Articles received only those powers which the former 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> <P> As the Confederation Congress attempted to govern the continually growing American states, delegates discovered that the limitations placed upon the central government rendered it ineffective at doing so . As the government's weaknesses became apparent, especially after Shays' Rebellion, individuals began asking for changes to the Articles . Their hope was to create a stronger national government . Initially, some states met to deal with their trade and economic problems . However, as more states became interested in meeting to change the Articles, a meeting was set in Philadelphia on May 25, 1787 . This became the Constitutional Convention . It was quickly realized that changes would not work, and instead the entire Articles needed to be replaced . On March 4, 1789, the government under the Articles was replaced with the federal government under the Constitution . The new Constitution provided for a much stronger federal government by establishing a chief executive (the President), courts, and taxing powers . </P> <P> The political push to increase cooperation among the then - loyal colonies began with the Albany Congress in 1754 and Benjamin Franklin's proposed Albany Plan, an inter-colonial collaboration to help solve mutual local problems . The Articles of Confederation would bear some resemblance to it . Over the next two decades, some of the basic concepts it addressed would strengthen and others would weaken, particularly the degree of deserved loyalty to the crown . With civil disobedience resulting in coercive, and what the colonials perceived as intolerable acts of Parliament, and armed conflict resulting in dissidents being proclaimed rebels and outside the King's protection, any loyalty remaining shifted toward independence and how to achieve it . In 1775, with events outpacing communications, the Second Continental Congress began acting as the provisional government that would run the American Revolutionary War and gain the colonies their collective independence . </P>
