This is my standard disclaimer that "Native Americans" span two continents and 15K years of history, at minimum. Variation is the rule, the exception.

This is also my standard gripe that "tribe" is an outdated term not used in contemporary academics works, given both it's ethnocentric biases and negative connotations.

All that said, you can read about the role of dwarfs in Mesoamerican (complex stratified state-level) societies in these past couple posts:

• What was the significance of dwarfs in Aztec society?

• I am a dwarf in a non-European civilization around the time of Christopher Columbus's arrival in the Americas. What is my life like?
