What enabled the growth of agriculture and civilization in the Nile River Valley?

Egyptian civilization developed along the Nile River in large part because the river's annual flooding ensured reliable, rich soil for growing crops.

Explanation:

Much of the history of Egypt is divided into three “kingdom” periods—Old, Middle, and New—with shorter intermediate periods separating the kingdoms. The term "intermediate" here refers to the fact that during these times Egypt was not a unified political power, and thus was in between powerful kingdoms. Even before the Old Kingdom period, the foundations of Egyptian civilization were being laid for thousands of years, as people living near the Nile increasingly focused on sedentary agriculture, which led to urbanization and specialized, non-agricultural economic activity.
