Why were the American articles of confederation innefective?

The American Articles of Confederation were ineffective due to their lack of a strong central government, which left the federal authority weak and unable to enforce laws or raise revenue. States operated independently, often prioritizing their own interests over national unity, leading to economic instability and trade conflicts. Additionally, the absence of an executive branch meant there was no effective means to implement or execute laws, further exacerbating governance issues. Ultimately, these weaknesses prompted the need for a more robust Constitution.
