Question

Why was Egypt interested in controlling the sources of nile​

Answer 1

The Nile River occupies a central place in the general perception of all Egyptians since the pre-Christian era of ancient Egypt. The river has been the nucleus of the ancient world and its lifeline, thereby justifying the sanctification of its waters. Ancient Egypt could not have existed without the river Nile. Since rainfall is almost non-existent in Egypt, the floods provided the only source of moisture to sustain crops.

Answer 2

Egyptian civilization developed along the Nile River in large part because the river's annual flooding ensured reliable, rich soil for growing crops. Repeated struggles for political control of Egypt showed the importance of the region's agricultural production and economic resources.
