The Articles of Confederation established a loose alliance among the 13 original states after the American Revolutionary War. It gave the central government very little power, which led to several problems. The states argued over land claims and had different currency systems. Congress could not raise taxes and had to rely on states for funding, but states often refused. Other countries took advantage of the disunity and disobeyed agreements. The major problem was that the Articles of Confederation did not give the central government enough power and authority over the states.
