HistoryBA, even after having viewed the video twice, it is apparent that you are still misunderstanding the fundamentals of a republic. It's not defined as a government that has laws; it's defined as a system where the rule of law is the governing force.

Oligarchical government serve the interests of those in charge before the interests of the people.
