Our Data, Who art in the Cloud, hallowed be Thy Index, Thy Algocracy come, Thy Classification be done, in IoT as it is in the Cloud, lead us not into Underfitting, but deliver us from Anecdotal Reasoning. For Thine is the algocracy and the market share and the celebrity: of the Network, and of the Server, and of the Holy Algorithm, DateTime.Now() and ever, and unto ages of ages. Amen.

Maybe, I have Big Gods: How Religion Transformed Cooperation and Conflict on my reading list but that seems to be more a part of later developments than city states. Before that came written laws, and before that came having states. I guess I'd recommend reading The World Until Yesterday followed by The Origins of Political Order.
