Why couldn’t the thirteen united states fight for independence against britain before the articles of confederation?

The thirteen original states couldn't fight for independence against Britain before the Articles of Confederation were approved because they were not fully organized yet.

Explanation:

The 13 original states agreed to come together as 'friends' (League of Friendship) based on the principle of equality for all and unite against the British in the pursuit of their freedom. These articles represented their first constitution and they outlined certain principles such as those related to the preservation of their independence and sovereignty. Once the Articles of Confederation were approved by the Second Continental Congress on November 15, 1777, the 13 states had a legal right to fight for their freedom, and so they did.
