Step-by-step explanation:
The articles of confederation was the first form of government in the United States.
However, it was weak because the people were afraid of tyranny. It had only one branch, Congress, hence, it had no executive or president to enforce the laws. The federal government was weak and had no power to pass taxes.
55 delegates met in Philadelphia to revive the A.O.C, however, they decided to create a whole new form of government. The constitution eventually replaced the A.O.C because it provided a stronger federal government, an executive, 3 branches, and also principles that would make sure no branch has too much power.
