The government under the Articles of Confederation was very "weak" in that it could only regulate trade between the states. Although its greatest achievement was that it allowed maximum freedom for citizens, its failure was that it could not tax the states adequately.
Explanation:
The Articles of Confederation and Perpetual Union, generally recognized as the Articles of Confederation, was the first governing document, or constitution, of the United States of America. The final draft was written in summer 1777 and adopted by the Second Continental Congress on November 15, 1777, in York, Pennsylvania after a year of debate. In practice, it worked as the de facto method of government adopted by the Congress till it became de jure by final confirmation on March 1, 1781.
One criticism by those who preferred a more powerful central state was that it needed taxing prestige; the central administration had to request supplies from the states. A second concern was its one-state, one-vote plank. The larger states were expected to contribute more but had only one vote, though they could remedy this by dividing into smaller states.
