Construction Begins on the Aswan High Dam

Postcolonial Egypt under President Gamal Abdel Nasser sought to modernize its economy and agriculture by harnessing the Nile River's seasonal floods and generating hydroelectric power. Soviet technical and financial assistance enabled the massive project after Western funding was withdrawn. On January 9, 1960, dynamite blasts marked the official start of construction on the Aswan High Dam in southern Egypt. The dam would eventually create Lake Nasser, one of the world's largest reservoirs, and provide electricity to millions while regulating irrigation for expanded farmland.
