The Jumano Tribe
Any Jumano warrior who brought back loot, scalps, and captives would become leader.
They absorbed different norms from various tribes and societies, rather than being completely true to their own traditions.
What became of them?
By the end of the seventeenth century, when Apache dominance extended into the lower Rio Grande valley and reached eastward to the upper Brazos and Colorado Rivers, the Jumanos had lost their entire territorial base, their trade routes were broken, and they ceased to exist as an identifiably distinct people.
