Question: was the articles of confederation acted as the first us constitution

Answer: Yes, 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 federal government received only those powers which the colonies had recognized as belonging to king and parliament.
