The correct answer could be The Bill of Rights.
During the Constitutional Convention, anti-federalists argued in favor of implementing a Bill of Rights in the new US Constitution. These individuals felt strongly about having a list of specific rights guaranteed to citizens. The anti-federalists argued that this helped to protect citizens from a tyrannical government. Along with this, it limited the power of the federal government. This was one of the main goals of the anti-federalists, as they felt an extremely strong federal (aka central) government could result in conflicts just like it did when the United States was controlled by the British government.
