Ancient River Valley Civilizations Introduction. The term civilization separates cultures that were more developed and settled than the previous hunter-gatherer societies. The first civilizations arose around 4000 BC in four river valleys across the globe. This unit is designed to examine the rise of these early civilizations and the emerging social complexity of populous societies.
