> 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 frame of government. 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 ratification by all the states.
