Jim Crow laws were more equal to apartheid in the states.

And apartheid has a real legal meaning in international agreements:

The crime of apartheid was further defined in 2002 by Article 7 of the Rome Statute of the International Criminal Court as encompassing inhumane acts such as torture, murder, forcible transfer, imprisonment, or persecution of an identifiable group on political, racial, national, ethnic, cultural, religious, or other grounds, “committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over any racial group or groups and committed with the intention of maintaining that regime”.

Which is much different than the US and the reservations.
