Answer:
Two reasons why the federalists wanted to approve the Constitution were the weakness of the federal government under the Articles of Confederation system, while the federal government was a Congress equitably constituted by the states of the nation, which could not exercise many of the powers. functions that he currently performs, such as collecting taxes; and since the lack of creation of a more effective federal government could cause internal conflicts between the states, in addition to showing weakness towards foreign nations.
In turn, the anti-federalists did not want the Constitution to be approved, as it proposed a one-person federal government, which they considered would become a tyranny, given the distrust that many colonists had regarding one-person governments such as monarchies; also, because they considered that a stronger federal state would limit the rights and prerogatives of the governments and citizens of each of the states in particular.
Finally, the Constitution was accepted by the anti-federalists, after the approval of the Bill of Rights, which guaranteed various rights of citizens, as well as limits to the federal government.
