The intent of the jim crow laws is: To segregate and disenfranchise black Americans.
It established the principle that everyone is subject to the law. Even the king. It also guaranteed the rights of individuals, and the right to a fair trial.
They wewre called the serfs/pesants.
The compromise helped gather enough support for the Constitution to ensure its ratification and for it to go to the adoption of the first ten amendments and the Bill of Rights. Anti-Federalists were scared that the Constitution would make the government overly-confertalized and that it would diminish individual rights and liberties.
