Which constitutional belief established a legal obligation on the part of the states to adhere to the Bill of Rights?

he Constitution was written in the summer of 1787 in Philadelphia, Pennsylvania, by delegates from 12 states, in order to replace the Articles of Confederation with a new form of government. It created a federal system with a national government composed of 3 separated powers, and included both reserved and concurrent powers of states. The president of the Constitutional Convention, the body that framed the new government, was George Washington, though James Madison is known as the "Father of the Constitution" because of his great contributions to the formation of the new government. Gouverneur Morris wrote the Constitution’s final language. The Constitution was a compact - though Federalists and Anti-Federalists disagreed over whether the states or the people were the agents of the compact.

In September of 1787, it was sent to the states for ratification. Nine of the 13 states would have to ratify it for the Constitution to become effective for those ratifying states. The future was not certain at all-a debate began among the states over ratification. Those who argued that the Constitution should be approved were called Federalists; those who argued against it were called Anti-Federalists.
