The Articles of Confederation the United States' first national constitution.  

The Articles of Confederation (or Articles of Confederation and Perpetual Union) was made because the United States of America needed a uniting constitution to unite them for their independence. The thirteen original states agreed to create this and became the first Continental Congress on November 15, 1777. The confederation was loose in nature and has a loose weak central government however; however its successes were on dealing the Western lands such as the Northwest Ordinance of 1787. That helped pay the Nation’s debts and launched western lands without so much chaos.
