Question

why did the federalists agree to add a bill of rights?
to gain anti - federalist support for ratification
to end the revolutionary war
to encourage loyalty to britain
to limit state power

Explanation:

The Federalists agreed to add a Bill of Rights mainly to gain the support of the Anti - Federalists, who were concerned about the potential for a strong central government to infringe on individual liberties. This was crucial for the ratification of the Constitution. The Revolutionary War had already ended by the time of the discussions about the Bill of Rights. Encouraging loyalty to Britain was not a factor, and the Bill of Rights was more about protecting individual rights from the federal government rather than limiting state power directly.

Answer:

To gain Anti - Federalist support for ratification
