Final answer:
The Congress under the Articles of Confederation was endowed with minimal power, leading to weaknesses in national governance and subsequent replacement by the Constitution, which granted more authority to the federal government.
Step-by-step explanation:
According to the Articles of Confederation, the Congress had little to no power. The Articles of Confederation established a decentralized form of governance that gave limited powers to the national Congress. Fearful of creating a central authority that might overstep its bounds and infringe upon civil liberties, the Founding Fathers designed the Articles to keep most of the power in the hands of the states. Under the Articles, the Confederation Congress could enact legislation but lacked the ability to enforce laws, with no executive or judicial branches to carry out or interpret those laws. Moreover, it could not impose taxes or raise armies on its own, relying instead on the willingness of the states to provide funds and troops. These limitations proved to be ineffective for a growing nation, leading to the eventual adoption of the Constitution, which established a more robust federal government structure.
