The most accurate statement regarding the circumstances preceding the ratification of the Constitution is:
Many supporters of the Constitution claimed that a national bill of rights was not necessary.
During the debates surrounding the ratification of the Constitution, many of its proponents, including figures like Alexander Hamilton, argued that a bill of rights was unnecessary because the Constitution itself limited the powers of the federal government and did not grant it authority to infringe upon individual rights. This argument was a key point in the debates between Federalists and Anti-Federalists.
While some states did have their own bills of rights at the time, the original Constitution did not include a national bill of rights; it wasn't until the adoption of the first ten amendments, known as the Bill of Rights, in 1791 that such protections were formally established at the federal level.
