People believe that conventions created specifically for the ratification of amendments form better representations of the people's will. State legislatures can oftentimes be biased for or against a certain amendment for their own wellbeing rather than that of the people they represent.
One major historical example of this can be seen in the use of ratification committees for the ratification of the American Constitution; the Founding Fathers believed that certain state legislatures would not ratify the Constitution even if the citizens of the states wanted to, so special conventions were created to more accurately portray the will of the people.
C. im pretty sure thats the answer bc ive had this question before.
It did not lead to the Civil War, what led to the civil war was the war of 1812. That was when U.S.A recognized that it needed to become stronger, and slaves were transported to the United States and put in the working class under bad conditions. Child labor and prejudice began there as well.
