Why did the Article fail?

The Articles of Confederation failed for many reasons. One failure is located in Article IX. It states that only congress has the exclusive right and power of determining on peace and war, also no treaty can be made by the states only congress. This proved to be a failure during the civil war. Southern states believed that they should have more power, and according to the articles it was not going to happen. In order to overcome this obstacle, many southern states seceded from the union.  All in all the Articles of confederation were to centered on a strong central government which was not what the people wanted then. The failures continued due to disagreements over federal and state power.
