The Tigris and Euphrates rivers in Mesopotamia were erratic. The rivers would flood or drought unpredictably and even shift their courses. Also, the Tigris had high banks which meant water irrigated from it would have to be drawn upward from the banks.
The Nile on the other hand followed a consistent annual inundation that brought water and fertile silt deposits right onto the crop fields. Egyptian farmers simply had to wait for the flood to recede some and plant their crops; the water and nutrient soil was already provided by the River.
The Zhou Dynasty used the notion of the Mandate of Heaven to defend the overthrow of the Shang Dynasty. The "Mandate of Heaven" is an earliest Chinese philosophical concept, which was created during the Zhou Dynasty(1046-256 BCE). The Mandate of Heaven decides whether a ruler of China is satisfactorily righteous to lead; if he does not accomplish his responsibilities as an emperor, then he fails the Mandate and thus the right to be emperor. Zhou leaders appealed that the Shang emperors had become fraudulent and unfit, so Heaven commanded their removal.
