early civilizations developed mostly around what geographic feature?

rivers

The four river valley civilizations were the Tigris & Euphrates Valleys, the Nile River Valley, the Indus River Valley, and the Yellow River Valley. Civilizations developed around rivers because their waters provided places to hunt and fish. Also, as the rivers flooded, the lands around them became fertile.

in 476 c.e. romulus, the last of the roman emperors in the west, was overthrown by the germanic leader odoacer, who became the first barbarian to rule in rome. the order that the roman empire had brought to western europe for 1000 years was no more.
