Yes, they were and one of my favorites to boot. My post about writing was related to human kind's initial rise from "tribal" cultures to cities, city states and civilization. Once the Sumerians invented writing, governments and bureaucracies could expand to new levels of complexity allowing a greatly enlarged area of influence and trade.Thorgalaeg said:Then Incas were not a civilization for you?
The interesting question raised by the Incas is: Were there any cultures similar to the Incas in sophistication and complexity in the Middle East prior to either Sumer or writing? I haven't seen any evidence for any. Or were the Incas just an aberation.
