The Federalists felt that this addition wasn't necessary, because they believed that the Constitution as it stood only limited the government not the people. The Anti- Federalists claimed the Constitution gave the central government too much power, and without a Bill of Rights the people would be at risk of oppression. Hope This Helps!
We had tried the constitution back when we were giving the states alot more power but it was not working and there were errors frequently. The Leaders of the Federalist party Were James Madison, John Jay, and our lord and savior Alexander Hamilton.
They came togethor to rewrite it for which they agreed to split the work of 25 papers.
One thing led to another and they made 85 XD John Jay- 5 papers he ended up getting sick James Madison- 29 papers Alexander Hamilton- 51 papers !
Any who the renewed constitution was decided to be placed again and its what upholds our country to this day. However inorder to remake the constitution we had to better unite the states much better and give a bit more power to the Government.
People like Thomas Jefferson totally freaked out because he thought we were going to become a monarchy again -_-
