It created a weak central government
The Articles of Confederation (1781), the first U.S.'s Constitution, was characterized for establishing a very weak central government consisting only of a Congress, it didn't even have a President, and for giving more power to the states, who had sovereignty.
Under the Constitution, the Congress had the power to make treaties and alliances, coin money, pay the war debts, maintain an army, appoint military officers, control Indian affairs, and to regulate foreign affairs, war, and the postal service. However, it did not have the power to levy taxes to the states to pay for those things, which eventually bring the newly independent America to an economic disaster
