Why did the articles of confederation need 9 out of 13 states to pass a law?

The Articles of Confederation required 9 out of 13 states to pass a law to ensure a significant consensus among the states, reflecting their sovereignty and independence. This high threshold aimed to prevent any single state from dominating the legislative process, promoting collaboration and compromise. However, this requirement also made it difficult to enact legislation efficiently, contributing to the weaknesses of the Confederation. Ultimately, this challenge highlighted the need for a stronger federal government, leading to the drafting of the U.S. Constitution.
