Answer:
The slaves that were owned by Native Americans in Indian territory were emancipated but to the laws that existed within each tribal society and to their terms of citizenship and belonging.
Step-by-step explanation:
It is little known that many of the groups who were forcibly removed from the Southeast in the Indian Removal Act were also slave owners. It is estimated for instance by author Tiya Miles that 1600 slaves of Cherokee slave owners also went west with their Cherokee owners into Indian Territory, what is now Oklahoma. When abolition occurred what happened is that the slaves gained the rights and responsibilities within each nation, so according to the treaties and self-governing principles that each tribe had with the United States government. There continues to be tension about this today in the Cherokee Nation for example as some African American slave descendants claim tribal membership based on the treaties that were in place at the time of emancipation.
