How did civilization evolve from the river valley time period to the end of the classical era?

Life has always been tied to water.

Explanation:

Thus, the world's oldest civilizations have just emerged in territories where there was enough water. For example, we can take the Euphrates and Tigris as the rivers on which culture was born. Egyptian civilization was also born thanks to the Nile River.

Water primarily provided man with a source of drinking water, thanks to the water, a man was able to satisfy his hygienic injuries. The water also provided him with the opportunity to irrigate his crops and to water his cattle.Thus, thanks to nature, man developed his original habitats. Over time, man evolved, and "domesticated" water and life, and a more complex irrigation system was designed.

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).
