Opponents to the new Constitution were known as Anti-federalists, although they agreed that a stronger federal government was needed,<u> they </u><u><em>feared that the Constitution would give too much power to the federal government and that it could lead to tyranny without a Bill of Rights in it. </em></u>
During the ratification progress Massachusetts, New York and Virginia argued the Constitution needed a Bill of Rights to protect the sovereignty of the states. <em>So as to ensure ratification of the Constitution, federalist James Madison agreed to write a Bill of Rights that would be added to the Constitution</em>.
The Bill of Rights is written in the first 10 amendments of the United States Constitution and protects the rights and liberties of the American citizens.
