The Nile Valley made significant contributions to civilization. The Nile River provided a constant source of life-giving water and created fertile lands that allowed for the development of a unique and resilient culture in ancient Egypt. The rich agricultural valleys along the Nile allowed for the growth of agrarian societies, and the access to materials in settled communities led to the development of art and architecture.
