Well, since you mentioned Cherokees we can definitely talk about them since they've been disowning blacks left & right.

Or we can talk about the 5 tribes, all who have owned slaves.

We can also focus on the Chickasaw tribe who consciously and deliberately chose to embrace racial ideology that degraded blackness and associated it exclusively with enslavement.

We can also look into revolts like those of Prince & Richard Harkins

Oh, let's not forget about the wealthy members of the Choctaw Tribes who had slaves so that they could hold onto political and cultural autonomy just to keep face for the white man while pursuing self-interested economic and diplomatic goals.

Damn! I almost forgot how tribes kept slaves even after slavery was over or even worst, sent them out to be arrested on grounds of bein a vagrant & auctioned them off to the highest bidder on purpose...which we all know is slavery by another name.

But, you're right, my "history game" isn't as nearly superior as yours & im talking out of my ass.
