The Antifederalists and Federalists were the first faction to disagree on this matter during the ratification of the Constitution. They feared a federal government would oppress their civil liberties and freedom the revolutionaries had so dearly fought for. However, from there grew the first political system. This ultimately paved the path for a system of parties to become integrated in the democratic government and discuss this issue. Parties argued over the institution of slavery and territorial expansion which ultimately led to clarify exactly what role the federal government had over the states.

Later many southern states had a lot of autonomy and felt like they should secede after issues of who held the ultimate power.
