Question

What was the main failure of the Articles of Confederation that eventually led to the US Constitution?

Answer 1

The main weaknesses of the Articles of Confederation were;
1) Under the Articles there was only a unicameral legislature so that there was no separation of powers.
2) Congress, under the Articles, did not have the power to tax which meant that they could never put their finances in order.
3) In order to change or amend the Articles, unanimous approval of the states was required which essentially meant that changes to the Articles were impossible.
4) For any major laws to pass they had to be approved by 9 or the 13 states which proved difficult to do so that even the normal business of running a government was difficult.
5) Under the Articles, Congress did not have the power to regulate commerce which will cause competition between states as well as diplomatic issues
