Final answer:
The Articles of Confederation were ineffective after the war due to the limited power of the national government and difficulty in passing laws and making changes. This led to a weak defense and challenges in governing the young republic.
Step-by-step explanation:
The Articles of Confederation proved to be ineffective after the war for several reasons. One major problem was the lack of power given to the national government. The central government was unable to raise an army or navy, resulting in a weak defense. Moreover, passing laws and amending the Articles required unanimous consent from all states, making it difficult to implement necessary changes.
