early region of state: nile valley

• Nile valley is noted for their dense populations, urbanization processes, and cultural innovation. The initial formation of these civilizations is based on the movement of peoples into the river valleys and plains. Egypt and the Nile Valley civilizations were defined by the rich alluvial soils that annual floods deposited along the Nile banks and in the delta and the flood plains. The use of water and the timing of flood seasons gave rise to a number of technological innovations, such as the calendar. These cultural and technological innovations also guaranteed the growth of large populations and increased the possibility that some of those populations would be located in central urban centers.
