Why were the American artistic of confederation ineffective?

The Articles of Confederation were ineffective primarily due to their lack of a strong central government, which limited Congress's ability to enforce laws, levy taxes, or regulate commerce. This led to financial instability and difficulties in addressing national issues, such as interstate disputes and defense. Additionally, the requirement for unanimous consent to amend the Articles made it nearly impossible to adapt to changing circumstances. Ultimately, these weaknesses prompted the eventual drafting of the U.S. Constitution to create a more robust federal system.
