Answer:
The AoC didn't work so it was a solution.
Explanation:
You didn't post a timeline so I'm going off of my own knowledge.
Before the Constitution there were the AoC, aka the Articles of Confederation. These articles were a mess for many reasons (which I recommend looking up later) the main one being a lack of federal government.
It was eventually decided that a new government needed to be formed to replace the AoC and the Constitution was made.
Again I don't have the timeline but another possible answer could be Shay's Rebellion which exposed the weakness of the AoC.
Hope this helps! :)))
