Just a quick note, Skeptic:
As a judge in a peacemaker court in an tributary Nation not one of the six Nations, but an Iroquoinaised culture... the constraints of the checks and ballences of Iroquain society is mitgated by the right to be bannished, to take ones share and start a new community, either within the confederacy or not. Much of what is written about Iroquain culture and law has been written by outsiders and does not reflect the reality of Iroquoian life. For example, bannishment was seen as a punnishment. That is as wrong as the applied titles of lords and such that were used to describe Iroquoi subchiefs.
However you are right that among the hundreds of Nations here there were a great variety of cultures, including some that approximated some eliments of capitolism and monarchy.
All the best
