Not until white people, no.

Source: am Cherokee and we didn’t have chattel slavery until we were deemed “the south” and tried to fit in. Then some (that were rich enough) got slaves, and treated them horribly. Before that, “slaves” were more like indentured servants in that they could conceivably get freedom and were considered part of the tribe.

There was a huge exhibit in Tahleqah in the Cherokee courthouse museum last summer all about it. Even named names.
