Answer: There is limited and historical evidence, so it's challenging to actually identify the basis of power.
Explanation: Here's why...
-a strong military: There is limited evidence of a strong military focus.
-a generous distribution of wealth: The economic system of the civilization is not fully understood.
-a belief of divine assistance: Some scholars suggest religious or spiritual aspects played a role.
-a democratic system of government: The evidence is insufficient to support the existence of a democratic system.
