Why did the Articles of Confederation fail?

The main  reason the Articles of Confederation failed was that they left a lot of power to the states and not to the central government.

The states had the right to basically run themselves and the government had no real control over what they were doing.  In Article II it says that each state "retains its sovereignty, freedom, and independence, and every power" meaning that the states have their independence to make decisions on what they please.  When then starts have their own independence then there really wouldn't be a United States of America.  The only real job that the government could do was to declare war and make peace.

Because of the Articles of Confederation there was no judicial system ever formed.  In Article V it states that each state has their own judicial affairs.  This also caused there to be no executive or legislative branch along with no president.

Overall the Articles of Confederation didn't live up to what it was suppose to be.  They basically were awful and had no purpose ifs any sort.
