A Constitutional Convention was held to address
these problems. After much debate, the decision was made to create a new constitution. The
development of the U.S. Constitution required many compromises among the state representatives.
Concern over the power of the federal government and the protection of individual rights made the
ratification of the Constitution uncertain. In order to gain Anti-Federalist support to ratify the
Constitution, the Federalists agreed to add a Bill of Rights, guaranteeing the protection of individual
rights.
(Hopefully this helps!)
