Which power was NOT granted to Congress under the Articles of Confederation?

The correct answer is that Congress was not granted the power to regulate commerce under the Articles of Confederation. The Articles established a confederation of states, creating a weak central government where the states retained most of their sovereignty. While Congress had the authority to make treaties and wage war, it lacked the power to regulate interstate commerce and trade effectively. This limitation resulted in economic disarray, as states often imposed tariffs on one another and engaged in trade disputes. The inability to regulate commerce highlighted the weaknesses of the Articles and contributed to calls for a stronger federal government, eventually leading to the Constitutional Convention.
